Editing

The grid control has support for dynamic insertion, updating and deletion of records. You can start the edit action either by double clicking the particular row or by selecting the required row and clicking on Edit icon in toolbar. Similarly, you can add new record to grid either by clicking on insert icon in toolbar or on an external button which is bound to call addRecord method of grid. Save and Cancel while on edit mode is possible using respective toolbar icon in grid.

Deletion of the record is possible by selecting the required row and clicking on Delete icon in toolbar.

The primary key for the data source should be defined in Columns definition, for editing to work properly. In Columns definition, particular primary column’s IsPrimaryKey property should be set to true. Refer the Knowledge base link for more information.

NOTE

  1. In grid, the primary key column will be automatically set to read only while editing the row, but you can specify primary key column value while adding a new record.
  2. The column which is specified as IsIdentity will be in readonly mode both while editing and adding a record. Also, auto incremented value is assigned to that IsIdentity column.

Toolbar with edit option

Using toolbar which is rendered at the top of the grid header, you can show all the CRUD related action. To enable toolbar and toolbar items, set ShowToolbar property as true and ToolbarItems. The default toolbar items are Add, Edit, Delete, Update and Cancel.

NOTE

For ToolbarItems property you can assign either string value (“Add”) or enum value (Syncfusion.JavaScript.ToolBarItems.Add).

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
              {
                col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                col.Field("CustomerID").HeaderText("Customer ID").Add();
				col.Field("EmployeeID").HeaderText("Employee ID").Add();
                col.Field("ShipCity").HeaderText("Ship City").Add();
                col.Field("ShipCountry").HeaderText("Ship Country").Add();
              }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                    var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                    ViewBag.DataSource = DataSource;
                    return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

Cell edit type and its edit options

The edit type of bound column can be customized using EditType property of Columns. The following Essential JavaScript controls are supported built-in by EditType. You can set the EditType based on specific data type of the column.

  • NumericTextBox control for integers, double, and decimal data types.
  • DatePicker control for date data type.
  • DateTimePicker control for date-time data type.
  • DropDownList control for list of data type.

And also you can define the model for all the editTypes controls while editing through EditOptions.

The following table describes EditType and their corresponding EditOptions of the specific data type of the column.

EditType EditParams Example
NumericTextBox

TextBoxes

NumericEditOptions(new EditorProperties() { DecimalPlaces = 2, })
DatePicker

DatePicker

DateEditOptions(new DatePickerProperties() { ButtonText="Now"})
DateTimePicker

DateTimePicker

DateTimeEditOptions(new DateTimePickerProperties() {Enabled=False})
DropDownList

DropDownList

<DropDownEditOptions(new DropDownListProperties() {ShowCheckbox=True})/>

NOTE

  1. If EditType is not set, then by default it will display the input element (“stringEdit”) while editing a column.
  2. For EditType property you can assign either string value (“NumericEdit”) or enum value (Syncfusion.JavaScript.EditingType.NumericEdit).

The following code example describes the above behavior

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
               {
			       col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Add();
				   col.Field("CustomerID").HeaderText("Customer ID").EditType(EditingType.StringEdit).Add();
				   col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).NumericEditOptions(new EditorProperties() { DecimalPlaces = 2 }).Add();
                   col.Field("ShipCity").HeaderText("Ship City").EditType(EditingType.DropdownEdit).Add();
                   col.Field("ShipCountry").HeaderText("Ship Country").Add();
                   col.Field("OrderDate").HeaderText("Order Date").EditType(EditingType.Datepicker).DateEditOptions(new DatePickerProperties() { ButtonText="Now"}).Format("{0:MM/dd/yyyy}").Add();            
                   col.Field("Verified").HeaderText("Verified").EditType(EditingType.BooleanEdit).Add();

                }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                   var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                   ViewBag.DataSource = DataSource;
                   return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

Cell Edit Template

On editing the column values, custom editor can be created by using EditTemplate property of Columns. It has three functions, they are

  1. Create - It is used to create the control at time of initialize.
  2. Read - It is used to read the input value at time of save.
  3. Write - It is used to assign the value to control at time of editing.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
              {
                 col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                 col.Field("CustomerID").HeaderText("Customer ID").Add();
			     col.Field("Freight").HeaderText("Freight").Add();
                 col.Field("ShipCountry").HeaderText("Ship Country").Add();
                 col.Field("ShipPostalCode").HeaderText("Ship Postal Code").EditTemplate(a => { a.Create("create").Read("read").Write("write"); }).Add();
                
              }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                   var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                   ViewBag.DataSource = DataSource;
                   return View();
                 }
             }
        }
<script id="template" type="application/javascript">
        function create() 
            {
	          return $("<input>");
            }
        function write(args) 
	       {
            args.element.ejMaskEdit({
                  maskFormat : "99-99-9999",
                  value : args.rowdata["ShipPostalCode"]
           });
           }
        function read(args) 
	       {
          return args.ejMaskEdit("get_StrippedValue");
          }
    
    </script>

The following output is displayed as a result of the above code example.

Edit Modes

Inline

Set EditMode as Normal, then the row itself is changed as edited row.

NOTE

For EditMode property you can assign either string value (Normal) or enum value (Syncfusion.JavaScript.EditMode.Normal).

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Normal); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
               {
                   col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Add();
				   col.Field("CustomerID").HeaderText("Customer ID").EditType(EditingType.StringEdit).Add();
				   col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).NumericEditOptions(new EditorProperties() { DecimalPlaces = 2 }).Add();
                   col.Field("ShipCountry").HeaderText("Ship Country").EditType(EditingType.DropdownEdit).Add();
                   col.Field("OrderDate").HeaderText("Order Date").EditType(EditingType.Datepicker).Format("{0:MM/dd/yyyy}").Add();            
               }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                   var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                   ViewBag.DataSource = DataSource;
                   return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

Inline Form

Set EditMode as InlineForm, then edit form will be inserted next to the row which is to be edited.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.InlineForm); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
               {
                   col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Add();
				   col.Field("CustomerID").HeaderText("Customer ID").EditType(EditingType.StringEdit).Add();
				   col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).NumericEditOptions(new EditorProperties() { DecimalPlaces = 2 }).Add();
                   col.Field("ShipCountry").HeaderText("Ship Country").Add();
                   col.Field("OrderDate").HeaderText("Order Date").EditType(EditingType.Datepicker).Format("{0:MM/dd/yyyy}").Add();            
                }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                    var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                    ViewBag.DataSource = DataSource;
                    return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

Inline Template Form

You can edit any of the fields pertaining to a single record of data and apply it to a template so that the same format is applied to all the other records that you may edit later.

Using this template support, you can edit the fields that are not bound to grid columns.

To edit the records using Inline template form, set EditMode as InlineFormTemplate and specify the template ID to InlineFormTemplateID property of EditSettings.

While using template form, you can change the HTML elements to appropriate JS controls based on the column type. This can be achieved by using ActionComplete event of grid.

NOTE

  1. value attribute is used to bind the corresponding field value while editing.
  2. name attribute is used to get the changed field values while saving the edited record.
  3. It’s a standard way to enclose the Template within the script tag with type as “text/x-jsrender”.
  4. For EditMode property you can assign either string value (InlineFormTemplate) or enum value (Syncfusion.JavaScript.EditMode.InlineTemplateForm)

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .ClientSideEvents(eve => { eve.ActionComplete("complete"); })
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.InlineFormTemplate).InlineFormTemplateID("#template");})
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
               {
                   col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Add();
				   col.Field("CustomerID").HeaderText("Customer ID").EditType(EditingType.StringEdit).Add();
                   col.Field("ShipCity").HeaderText("Ship City").EditType(EditingType.DropdownEdit).Add();

Before the template elements are converted to JS controls

After the template elements are converted to JS controls using actionComplete event.

NOTE

To render the EJ MVC form controls like DatePicker, Dropdownlist, NumericTextBox in the template edit form, from the partial view, refer the KB How render ejControls in the Edit Form Template of the MVC Grid.

Dialog

Set EditMode as Dialog to edit data using a dialog box, which displays the fields associated with the data record being edited.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Dialog); })

Dialog Template Form

You can edit any of the fields pertaining to a single record of data and apply it to a template so that the same format is applied to all the other records that you may edit later.

Using this template support, you can edit the fields that are not bound to grid columns.

To edit the records using Dialog template form, set EditMode as ‘DialogTemplate’ and specify the template id to DialogEditorTemplateID property of EditSettings.

While using template, you can change the elements that are defined in the Template, to appropriate JS controls based on the column type. This can be achieved by using ActionComplete event of grid.

NOTE

  1. value attribute is used to bind the corresponding field value while editing.
  2. name attribute is used to get the changed field values while save the edited record.
  3. For EditMode property you can assign either string value (DialogTemplate) or enum value (Syncfusion.JavaScript.EditMode.DialogTemplate).

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .ClientSideEvents(eve => { eve.ActionComplete("complete"); })

External Form

By setting the EditMode as ExternalForm, the edit form is opened outside the grid content.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.ExternalForm); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
                {
                   col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Add();
				   col.Field("CustomerID").HeaderText("Customer ID").EditType(EditingType.StringEdit).Add();
				   col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).NumericEditOptions(new EditorProperties() { DecimalPlaces = 2 }).Add();
                   col.Field("ShipCountry").HeaderText("Ship Country").Add();
                   col.Field("OrderDate").HeaderText("Order Date").EditType(EditingType.Datepicker).Format("{0:MM/dd/yyyy}").Add();            
                }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()

                    ViewBag.DataSource = DataSource;
                    return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

Form Position:

You can position an External edit form in the following two ways.

  1. Top-right
  2. Bottom left

This can be achieved by setting the FormPosition property of EditSettings as ‘TopRight’ or ‘BottomLeft’.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.ExternalForm).FormPosition(FormPosition.TopRight);  })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>

NOTE

To render the EJ MVC form controls like DatePicker, Dropdownlist, NumericTextBox in the template edit form, from the partial view, refer the KB How render ejControls in the Edit Form Template of the MVC Grid.

Batch / Excel-like

Users can start editing by clicking a cell and typing data into it. Edited cell will be marked while navigating to next cell or any other row, so that you know which fields or cells has been edited. Set EditMode as Batch to enable batch editing.

NOTE

getBatchChanges method of grid holds the unsaved record changes.
Refer the KB link for “How to suppress grid confirmation messages” in batch mode.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Batch); })

Confirmation messages

To show the confirm dialog while saving or discarding the Batch changes (discarding during the grid action like filtering, sorting and paging), set ShowConfirmDialog as true.

NOTE

ShowConfirmDialog property is only for Batch editing mode.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)

Column Validation

We can validate the value of the added or edited record cell before saving.

The below validation script files are needed when editing is enabled with validation.

  1. jquery.validate.min.js
  2. jquery.validate.unobtrusive.min.js

jQuery Validation

You can set validation rules using ` ValidationRules property of Columns`. The following are jQuery validation methods.

Grid supports all the standard validation methods of jQuery, please refer the jQuery validation documentation link for more information.

To return custom validation message from server end, please refer this KB link.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                  toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
              {
                col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).ValidationRules(v => v.AddRule("required",true).AddRule("number", true)).Add();
                col.Field("CustomerID").HeaderText("Customer ID").ValidationRules(v => v.AddRule("required", true).AddRule("minlength", 3)).Add();
			    col.Field("ShipCity").HeaderText("Ship City").Add();
                col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).ValidationRules(v => v.AddRule("range", "[0,1000]")).Add();
                col.Field("ShipCountry").HeaderText("Ship Country").Add();
            }))
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                   var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                   ViewBag.DataSource = DataSource;
                   return View();
                 }
             }
        }

The following output is displayed as a result of the above code example.

NOTE

  1. Refer this Knowledge Base link to perform server side validation in Grid.

Custom Validation

In addition to jQuery validation methods, you can also add your own custom validation methods for a specific column. Function call to custom validator function to be mentioned within ValidationRules property of Columns.

Using messages property of ValidationRules you can specify the error message for that column.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource((IEnumerable<object>)ViewBag.DataSource)
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
              {
                col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                col.Field("CustomerID").HeaderText("Customer ID").ValidationRules(v => v.AddRule("customRegex", 5)).Add();
			    col.Field("ShipCity").HeaderText("Ship City").Add();
                col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).ValidationRules(rule => rule.AddRule("customCompare", new List<object>() { 0, 1000 })).Add();
                col.Field("ShipCountry").HeaderText("Ship Country").Add();
              }))
<script type="text/javascript">
               $(function () {
                  $.validator.addMethod("customCompare", function (value, element, params) {
                  return element.value > params[0] && element.value < params[1];
                }, "Freight value must be between 0 and 1000");

                  $.validator.addMethod("customRegex", function (value, element, params) {
                  if (element.value.length == params)
                  return true;
                  return false;
               }, "Customer ID must be 5 characters");
            });
          </script>
namespace MVCSampleBrowser.Controllers
        {
            public class GridController : Controller
              { 
                public ActionResult GridFeatures()
                 {
                   var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                   ViewBag.DataSource = DataSource;
                   return View();
                 }
             }
        }

Persisting data in Server

Edited data can be persisted in database using RESTful web services.

All the CRUD operations in grid are done through DataManager. DataManager have an option to bind all the CRUD related data in server side. Please refer the [‘link’] to know about the DataManager.

For you information ODataAdaptor persist data in server as per OData protocol.

In the below section, we have explained how to get the edited data details at the server side using URLAdaptor.

URL Adaptor

You can use the UrlAdaptor of DataManger when binding datasource from remote data. At initial load of Grid, using URL property of DataManager, data are fetched from remote data and bound to Grid. You can map CRUD operation in Grid to Server-Side Controller action using the properties InsertURL, RemoveURL, UpdateURL, CrudURL and BatchURL.

The following code example describes the above behavior.

@(Html.EJ().Grid<Object>("FlatGrid")
            .Datasource(datasource => datasource.URL("Home/DataSource").UpdateURL("Home/Update").InsertURL("Home/Insert").RemoveURL("Home/Delete").Adaptor(AdaptorType.UrlAdaptor))
            .AllowPaging()
            .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
            .ToolbarSettings(toolbar =>
               {
                   toolbar.ShowToolbar().ToolbarItems(items =>
                   {
                       items.AddTool(ToolBarItems.Add);
                       items.AddTool(ToolBarItems.Edit);  
                       items.AddTool(ToolBarItems.Delete);
                       items.AddTool(ToolBarItems.Update);
                       items.AddTool(ToolBarItems.Cancel);
                   });
               })
            .Columns(col =>
              {
                col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                col.Field("CustomerID").HeaderText("Customer ID").Add();
				col.Field("EmployeeID").HeaderText("Employee ID").Add();
                col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).Add();
                col.Field("ShipCity").HeaderText("Ship City").Add();
                col.Field("ShipCountry").HeaderText("Ship Country").Add();
             }))
Also when you use `UrlAdaptor`, you need to return the data as `JSON` and the JSON object must contain a property as `result` with dataSource as its value and one more property `count` with the dataSource total records count as its value. The following code example describes the above behavior.
namespace MVCSampleBrowser.Controllers
        {
           public class GridController : Controller
              { 
                public ActionResult DataSource(DataManager dataManager)
                 {
                   IEnumerable DataSource = OrderRepository.GetAllRecords();
                   DataResult result = new DataResult();
                   DataOperations operation = new DataOperations();
                   result.result = DataSource;
                   result.count = result.result.AsQueryable().Count();
                   if (dataManager.Skip > 0)
                   result.result = operation.PerformSkip(result.result, dataManager.Skip);
                   if (dataManager.Take > 0)
                   result.result = operation.PerformTake(result.result, dataManager.Take);
                   return Json(result, JsonRequestBehavior.AllowGet);
               }
           public class DataResult
              {
                public IEnumerable result { get; set; }
                public int count { get; set; }
              }
          }
     }

The grid actions (sorting, filtering, paging, searching, and aggregates) details are obtained in the ‘DataManager’ class. While initializing the grid, paging only enabled hence in the below screen shot paging details are bound to the DataManager class.

Please refer the below screen shot.

Also, using ‘DataOperations’ helper class you can perform grid action at server side. The in-built methods that we have provided in the DataOperations class are listed below.

  1. PerformSorting
  2. PerformFiltering
  3. PerformSearching
  4. PerformSkip
  5. PerformTake
  6. PerformWhereFilter
  7. PerformSelect
  8. Execute

RemoteSave Adaptor:

RemoteSaveAdaptor is used for binding local data and performs all data operations in client-side. It interacts with server-side only for CRUD operations to pass the modified records.

Refer to the following code example

  • razor
  • @(Html.EJ().Grid<object>("FlatGrid")
                    .Datasource(dataSource => dataSource.Json((IEnumerable<object>)ViewBag.datasource).UpdateURL("/Home/Update")
                    .InsertURL("/Home/Insert").RemoveURL("/Home/Remove").Adaptor(AdaptorType.RemoteSaveAdaptor))
                    .AllowPaging()
                    .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
                    .ToolbarSettings(toolbar =>
                    {
                    toolbar.ShowToolbar().ToolbarItems(items =>
                        {
                            items.AddTool(ToolBarItems.Add);
                            items.AddTool(ToolBarItems.Edit);
                            items.AddTool(ToolBarItems.Delete);
                            items.AddTool(ToolBarItems.Update);
                            items.AddTool(ToolBarItems.Cancel);
                        });
                    })
                .Columns(col =>
                    {
                    col.Field("OrderID").IsPrimaryKey(true).Add();
                    col.Field("EmployeeID").Add();
                    col.Field("CustomerID").Add();
                    col.Field("ShipCountry").Add();
                    col.Field("Freight").Add();
                })
            )

    Accessing CRUD action request details in server side:

    The ‘Server-Side’ function must be declared with the following parameter name for each editing functionality.

    Parameters Table

    Action Parameter Name Example
    Update,Insert value public ActionResult Update(EditableOrder value){ }
    public ActionResult Insert(EditableOrder value){ }
    Remove key public ActionResult Remove(int key){ }
    Batch Add added public ActionResult BatchUpdate(string action, List <EditableOrder> added, List <EditableOrder> changed, List <EditableOrder> deleted, int? key){ }
    Batch Update changed
    Batch Delete deleted
    Crud Update,Crud Insert value, action public ActionResult CrudUrl(EditableOrder value, string action){ }
    Crud Remove action, key, keyColumn public ActionResult CrudUrl(string action, int? key, string keyColumn){ }
    Crud Remove - Multi Delete action, key, deleted public ActionResult CrudUrl(string action, string key, List <EditableOrder> deleted){ }

    Insert Record:

    Using InsertURL property, you can specify the controller action mapping URL to perform insert operation at server side.

    The following code example describes the above behavior.

  • c#
  • public ActionResult Insert(EditableOrder value)
          {
            OrderRepository.Add(value);
            var data = OrderRepository.GetAllRecords();
            return Json(value, JsonRequestBehavior.AllowGet);
          }

    The newly added record details are bound to the ‘value’ parameter. Please refer the below image.

    Update Record:

    Using UpdateURL property, you can specify the controller action mapping URL to perform save/update operation at server side.

    The following code example describes the above behavior.

  • c#
  • public ActionResult Update(EditableOrder value)
    {
        OrderRepository.Update(value);
        var data = OrderRepository.GetAllRecords();
        return Json(value, JsonRequestBehavior.AllowGet);
    }

    The updated record details are bound to the ‘value’ parameter. Please refer the below image.

    Delete Record:

    Using RemoveURL property, you can specify the controller action mapping URL to perform delete operation at server side.

    The following code example describes the above behavior.

  • c#
  • public ActionResult Remove(int key)
    {
      OrderRepository.Delete(key);
      var data = OrderRepository.GetAllRecords();
      return Json(key, JsonRequestBehavior.AllowGet);
    }

    The deleted record primary key value is bound to the ‘key’ parameter. Please refer the below image.

    CRUD URL:

    Instead of specifying separate controller action method for CRUD (insert, update and delete)operation, using CrudURL property you can specify the controller action mapping URL to perform all the CRUD operation at server side using single method.

    The action parameter of CrudURL is used to get the corresponding CRUD action.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<Object>("FlatGrid")
                .Datasource(datasource => datasource.URL("Home/DataSource").CrudURL("Home/CrudUpdate").Adaptor(AdaptorType.UrlAdaptor))
                .AllowPaging()
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
                .ToolbarSettings(toolbar =>
                   {
                       toolbar.ShowToolbar().ToolbarItems(items =>
                       {
                           items.AddTool(ToolBarItems.Add);
                           items.AddTool(ToolBarItems.Edit);  
                           items.AddTool(ToolBarItems.Delete);
                           items.AddTool(ToolBarItems.Update);
                           items.AddTool(ToolBarItems.Cancel);
                       });
                   })
                .Columns(col =>
                {
                    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                    col.Field("CustomerID").HeaderText("Customer ID").Add();
    				col.Field("EmployeeID").HeaderText("Employee ID").Add();
                    col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).Add();
                    col.Field("ShipCity").HeaderText("Ship City").Add();
                    col.Field("ShipCountry").HeaderText("Ship Country").Add();
                }))
    public ActionResult CrudUpdate(EditableOrder value, string action, int key)
            {
    	       if (action == "update")
                    OrderRepository.Update(value);
                else if (action == "insert")
                    OrderRepository.Add(value);
                else if (action == "remove")
                    OrderRepository.Delete(key);
                return Json(value, JsonRequestBehavior.AllowGet);
            }

    Please refer the below image to know about the action parameter

    NOTE

    If you specify InsertURL along with CrudURL then while adding InsertURL only called.

    Batch URL:

    The BatchURL property supports only for batch editing mode. You can specify the controller action mapping URL to perform Batch operation at server side.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<Object>("FlatGrid")
                .Datasource(datasource => datasource.Json((IEnumerable<object>)ViewBag.dataSource).BatchURL("Home/BatchUpdate").Adaptor(AdaptorType.UrlAdaptor))
                .AllowPaging()
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
                .ToolbarSettings(toolbar =>
                   {
                       toolbar.ShowToolbar().ToolbarItems(items =>
                       {
                           items.AddTool(ToolBarItems.Add);
                           items.AddTool(ToolBarItems.Edit);  
                           items.AddTool(ToolBarItems.Delete);
                           items.AddTool(ToolBarItems.Update);
                           items.AddTool(ToolBarItems.Cancel);
                       });
                   })
                .Columns(col =>
                  {
                    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                    col.Field("CustomerID").HeaderText("Customer ID").Add();
    				col.Field("EmployeeID").HeaderText("Employee ID").Add();
                    col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).Add();
                    col.Field("ShipCity").HeaderText("Ship City").Add();
                    col.Field("ShipCountry").HeaderText("Ship Country").Add();
                 }))
    public ActionResult BatchUpdate(string action, List<EditableOrder> added, List<EditableOrder> changed, List<EditableOrder> deleted, int? key)
    		{
    			 if (changed != null)
                    OrderRepository.Update(changed);
                if (deleted != null)
                    OrderRepository.Delete(deleted);
                if (added != null)
                    OrderRepository.Add(added);
                var data = OrderRepository.GetComplexRecords();
                return Json(new { changed = changed, added = added, deleted = deleted }, JsonRequestBehavior.AllowGet);
    	    }

    Please refer the below image for more information about batch parameters

    Performing CRUD Operation on ODataV4 Adaptor

    ODataV4 Adaptor that is extended from ODataAdaptor, is used for consuming data from ODataV4 Service

    To consume ODataV4 service, set the service link to the Url property of Grid DataSource and you can set Adaptor type as AdaptorType.ODataV4Adaptor to the Adaptor Property of Grid DataManager. We can bind this DataManager as dataSource for the Grid.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<object>("Grid")
                .Datasource(datasource => { datasource.URL("/odata/Orders").Adaptor(AdaptorType.ODataV4Adaptor); })
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Normal); })
                .ToolbarSettings(toolbar =>
                {
                    toolbar.ShowToolbar().ToolbarItems(items =>
                    {
                        items.AddTool(ToolBarItems.Add);
                        items.AddTool(ToolBarItems.Edit);
                        items.AddTool(ToolBarItems.Delete);
                        items.AddTool(ToolBarItems.Update);
                        items.AddTool(ToolBarItems.Cancel);
                    });
                })
             .AllowPaging()
             .Columns(col =>
              {
                 col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).IsIdentity(true).Width(50).Add();
                 col.Field("EmployeeID").HeaderText("Employee ID").Width(50).Add();
                 col.Field("ShipCity").HeaderText("ShipCity").Width(50).Add();
              })
    )
    To perform the CRUD Operation in ODataV4 we need not explicitly mention any URL for Insert, Update or Delete operations in grid instead we can retrieve it using the `PUT`, `POST` and `DELETE` semantics of the OData which will be handled on the URL property already specified. The following code example describes the above behavior.
    namespace MVCSampleBrowser.Controllers
            {
               public class GridController : ODataController
                  { 
                    // GET: Orders
                     NORTHWNDEntities db = new NORTHWNDEntities();
                      [EnableQuery]
                     public IQueryable<Order> Get()
                      {
                            return db.Orders;
                       }
                  }
           }

    The Get method returns the entire Order collection. This Get Method returns the data to the Grid from the database.

    Insert Record:

    To add a new data to the database, add the following method to controller page.

    The following code example describes the above behavior.

  • c#
  • // POST odata/Orders
            public async Task<Order> Post(Order order) 
            {
                db.Orders.Add(order);
                await db.SaveChangesAsync();
                return order;
                
            }

    Please refer the below image.

    Here the newly added record details are bound to the ‘order’ parameter.

    Update Record:

    To update an existing data from the database, add the following method to Controller page.

    The following code example describes the above behavior.

  • c#
  • // PUT odata/Orders(5)
            public async Task<Order> Put(Order order) 
            {
                var entity =  await db.Orders.FindAsync(order.OrderID);
                db.Entry(entity).CurrentValues.SetValues(order);
                await db.SaveChangesAsync();
                return order;
            }

    Please refer the below image.

    Here the modified row data will be obtained in the order parameter.

    Delete Record:

    To delete a data from the database, add the following method to controller.

    The following code example describes the above behavior.

  • c#
  • // DELETE odata/Orders(5)
            public async Task<IHttpActionResult> Delete([FromODataUri] int key)
            {
                var data = await db.Orders.FindAsync(key);
                if (data == null)
                {
                    return NotFound();
                }
    
                db.Orders.Remove(data);
                await db.SaveChangesAsync();
                return StatusCode(HttpStatusCode.NoContent);          
            }

    Please refer the below image.

    The deleted record primary key value is bound to the ‘key’ parameter.

    Please refer the below image.

    Adding New Row Position

    To add new row in the top or bottom position of grid content, set RowPosition property of EditSettings depending on the requirement.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<Object>("FlatGrid")
                .Datasource((IEnumerable<object>)ViewBag.DataSource)
                .AllowPaging()
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().RowPosition(RowPosition.Bottom) })
                .ToolbarSettings(toolbar =>
                   {
                       toolbar.ShowToolbar().ToolbarItems(items =>
                       {
                           items.AddTool(ToolBarItems.Add);
                           items.AddTool(ToolBarItems.Edit);  
                           items.AddTool(ToolBarItems.Delete);
                           items.AddTool(ToolBarItems.Update);
                           items.AddTool(ToolBarItems.Cancel);
                       });
                   })
                .Columns(col =>
                  {
                    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                    col.Field("CustomerID").HeaderText("Customer ID").Add();
    			    col.Field("ShipCity").HeaderText("Ship City").Add();
                    col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).Add();
                    col.Field("ShipCountry").HeaderText("Ship Country").Add();
                 }))
    namespace MVCSampleBrowser.Controllers
            {
                public class GridController : Controller
                  { 
                    public ActionResult GridFeatures()
                     {
                       var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                       ViewBag.DataSource = DataSource;
                       return View();
                     }
                 }
            }

    The following output is displayed as a result of the above code example.

    Render with blank row for easy add new

    The blank add new row is displayed in the grid content during grid initialization itself to add a new record easily. To enable show add new row by default, set ShowAddNewRow property of EditSettings as true.

    The blank add new row is displayed either in the top or bottom of the corresponding page, its position is based on the RowPosition property of EditSettings.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<Object>("FlatGrid")
                .Datasource((IEnumerable<object>)ViewBag.DataSource)
                .AllowPaging()
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().ShowAddNewRow(); })
                .ToolbarSettings(toolbar =>
                   {
                       toolbar.ShowToolbar().ToolbarItems(items =>
                       {
                           items.AddTool(ToolBarItems.Add);
                           items.AddTool(ToolBarItems.Edit);  
                           items.AddTool(ToolBarItems.Delete);
                           items.AddTool(ToolBarItems.Update);
                           items.AddTool(ToolBarItems.Cancel);
                       });
                   })
                .Columns(col =>
                  {
                    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                    col.Field("CustomerID").HeaderText("Customer ID").Add();
    			    col.Field("ShipCity").HeaderText("Ship City").Add();
                    col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).Add();
                    col.Field("ShipCountry").HeaderText("Ship Country").Add();
                  }))
    namespace MVCSampleBrowser.Controllers
            {
                public class GridController : Controller
                  { 
                    public ActionResult GridFeatures()
                     {
                       var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                       ViewBag.DataSource = DataSource;
                       return View();
                     }
                 }
            }

    The following output is displayed as a result of the above code example.

    NOTE

    1. If it is remote, then the newly added record is placed based on the index from current view data.
    2. If it is local, then the newly added record is added at the top of the page even if the added new RowPosition is mentioned as “Bottom”.

    Default column values on add new

    While adding new record in grid, there is an option to set the default value for the columns. Using DefaultValue property of Columns you can set the default values for that particular column while editing or adding a new row.

    The following code example describes the above behavior.

    @(Html.EJ().Grid<Object>("FlatGrid")
                .Datasource((IEnumerable<object>)ViewBag.DataSource)
                .AllowPaging()
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().ShowAddNewRow(); })
                .ToolbarSettings(toolbar =>
                   {
                       toolbar.ShowToolbar().ToolbarItems(items =>
                       {
                           items.AddTool(ToolBarItems.Add);
                           items.AddTool(ToolBarItems.Edit);  
                           items.AddTool(ToolBarItems.Delete);
                           items.AddTool(ToolBarItems.Update);
                           items.AddTool(ToolBarItems.Cancel);
                       });
                   })
                .Columns(col =>
                   {
                     col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Add();
                     col.Field("CustomerID").HeaderText("Customer ID").Add();
    			     col.Field("ShipCity").HeaderText("Ship City").DefaultValue("Bern").Add();
                     col.Field("Freight").HeaderText("Freight").EditType(EditingType.NumericEdit).DefaultValue(45).Add();
                     col.Field("ShipCountry").HeaderText("Ship Country").DefaultValue("Brazil").Add();
                   }))
    namespace MVCSampleBrowser.Controllers
            {
                public class GridController : Controller
                  { 
                    public ActionResult GridFeatures()
                     {
                       var DataSource = new NorthwindDataContext().OrdersViews.ToList();
                       ViewBag.DataSource = DataSource;
                       return View();
                     }
                 }
            }

    The following output is displayed as a result of the above code example.
