Editing in EJ 1 ASP.NET MVC Kanban (Kanban Board)

28 May 2019 / 24 minutes to read

The Kanban control has support for dynamic insertion, updating and deletion of cards.

Set AllowEditing and AllowAdding property as true to enable editing/inserting respectively. The primary key for the data source should be defined in PrimaryKey, for editing to work properly.

You can start the edit action by double clicking the particular card. Similarly, you can add new card to Kanban either by double clicking the particular cell or on an external button which is bound to call addCard method of Kanban.

Deletion of the card is possible by using deleteCard by passing primary key as attribute.

NOTE

In Kanban, the primary key column will be automatically set to read only while editing the card which is to avoid duplicate entry in the cards.

Configuring Edit Items

You need to configure the list of data source fields that are allowable in editing state using EditItems property. The Field property of EditItems needs to be mapped with data source fields.

You can map the data source field as title to edit form using Title property of Fields. By default, it’s mapped with PrimaryKey.

The following code example describes the above behavior.

@(Html.EJ().Kanban("Kanban")
        .DataSource((IEnumerable<object>)ViewBag.datasource)
        .Columns(col =>
        {
            col.HeaderText("Backlog").Key("Open").Add();
            col.HeaderText("In Progress").Key("InProgress").Add();
            col.HeaderText("Done").Key("Close").Add();
        })
        .KeyField("Status")

        .Fields(field =>
        {
            field.Content("Summary")
                .PrimaryKey("Id");
        })
        .EditSettings(edit =>
        {
            edit.AllowAdding(true)
                .AllowEditing(true)
                .EditItems(e =>
                {
                    e.Field("Id").Add();
                    e.Field("Status").EditType(KanbanEditingType.Dropdown).Add();
                    e.Field("Assignee").EditType(KanbanEditingType.Dropdown).Add();
                    e.Field("Estimate").EditType(KanbanEditingType.Numeric).NumericEditOptions(new EditorProperties()
                    {
                        DecimalPlaces = 2
                    }).Add();
                    e.Field("Summary").EditType(KanbanEditingType.TextArea).Add();
                });  
            })           
    )
namespace MVCSampleBrowser
    {
        public partial class KanbanController : Controller
        {
            //
            // GET: /Kanban/

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

Edit modes

Dialog

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

NOTE

For EditMode property you can assign either string value (“Dialog”) or enum value (ej.Kanban.EditMode.Dialog).

The following code example describes the above behavior.

@(Html.EJ().Kanban("Kanban")

            col.HeaderText("Done").Key("Close").Add();
        })
        .KeyField("Status")

        .Fields(field =>
        {

Dialog in ASP NET MVC kanban control

Dialog Template Form

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

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

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

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 card.
  3. For EditMode property you can assign enum value (KanbanEditMode.DialogTemplate).

The following code example describes the above behavior.

  • html
  • <script id="template" type="text/template">

    While using template, you can change the elements that are defined in the template, to appropriate Syncfusion JS controls based on the column type. This can be achieved by using ActionComplete event of Kanban. Please refer to following code snippets.

  • javascript
  • function complete(args) {
            if ((args.requestType == "beginedit" || args.requestType == "add") && args.model.editSettings.editMode == "dialogtemplate") {
                $("#Estimate").ejNumericTextbox({ value: parseFloat($("#Estimate").val()), width: "175px", height: "34px", decimalPlaces: 2 });
                $("#Assignee").ejDropDownList({ width: '175px' });
                $("#Status").ejDropDownList({ width: '175px' });
                $("#Priority").ejDropDownList({ width: '175px' });
                if (args.requestType == "beginedit" || args.requestType == "add") {
                    $("#Assignee").ejDropDownList("setSelectedValue", args.data['Assignee']);
                    $("#Priority").ejDropDownList("setSelectedValue", args.data['Priority']);
                    $("#Status").ejDropDownList("setSelectedValue", args.data['Status']);
                }
            
            }
        }

    Cell edit type and its params

    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.

    EditType EditParams Description Example
    Numeric

    TextBoxes

    control for integers, double, and decimal data’s NumericEditOptions(new EditorProperties() { DecimalPlaces = 2 })
    String HTML Textbox HTML Textbox -
    DatePicker

    DatePicker

    control for date data DateEditOptions(new DatePickerProperties() { ButtonText="Now"})
    DateTimePicker

    DateTimePicker

    control for date data-time data DateTimeEditOptions(new DateTimePickerProperties() { Enabled=true})
    DropDown

    DropDownList

    control for list of data DropdownEditOptions(new DropDownListProperties() { AllowGrouping=true})
    RTE

    RTE

    control for customizing text in RTE format RTEEditOptions(new RTEproperties() { EnableResize=true})
    TextArea HTML TextArea Control for multi-line plain-text editing

    NOTE

    1. If EditType is not set, then by default it will display HTML textbox while editing a card.
    2. For EditType property you can assign either string value (numericedit) or enum value (ej.Kanban.EditingType.Numeric).

    The following code example describes the above behavior.

    Column Validation

    We can validate the value of the added or edited card 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

    NOTE

    If you enabled the unobtrusive option, then need to refer the jquery.validate.unobtrusive.min.js

    file in your application along with the other script.

    jQuery Validation

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

    List of jQuery validation methods

    Rules Description
    required Requires an element.
    remote Requests a resource to check the element for validity.
    minlength Requires the element to be of given minimum length.
    maxlength Requires the element to be of given maximum length.
    rangelength Requires the element to be in given value range.
    min The element requires a given minimum.
    max The element requires a given maximum.
    range Requires the element to be in a given value range.

    Column validation in ASP NET MVC kanban control

    Persisting data in server

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

    All the CRUD operations in Kanban 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.

    URL Adaptor

    You can use the UrlAdaptor of DataManager when binding DataSource from remote data. At initial load of Kanban, using URL property of DataManager, data are fetched from remote data and bound to Kanban. You can map CRUD operation in Kanban to Server-Side Controller action using the property CrudURL.

    The following code example describes the above behavior.

    @(Html.EJ().Kanban("Kanban")
           .DataSource(data => data.URL("GetData").CrudURL("Crud").Adaptor(AdaptorType.UrlAdaptor))
                       .Columns(col =>
                       {
                           col.HeaderText("Backlog").Key("Open").ShowAddButton(true).Add();
                           col.HeaderText("In Progress").Key("InProgress").Add();
                           col.HeaderText("Done").Key("Close").Add();
                       })
                               .CustomToolbarItems(custom =>
                                           {
                                               custom.Template("#Delete").Add();
                                           })
                      .EditSettings(edit =>
                              {
                                  edit.AllowAdding(true)
                                      .AllowEditing(true)
                                      .EditItems(e =>
                                      {
                                          e.Field("Id").Add();
                                          e.Field("Status").Add();
                                          e.Field("Assignee").Add();
                                          e.Field("Estimate").Add();
                                          e.Field("Summary").Add();
                                      }).EditMode(KanbanEditMode.Dialog);
                              })
                      .KeyField("Status")
                      .Fields(field =>
                      {
                          field.Content("Summary")
                               .PrimaryKey("Id")
                               .Priority("RankId");
                      })
                      .ClientSideEvents(eve => eve.ToolBarClick("toolbarClick"))
        )
        
        <script type="text/javascript">
         function toolbarClick(args) {
            if (args.itemName == "Delete" && this.element.find(".e-kanbancard").hasClass("e-cardselection")) {
                var selected = this.element.find(".e-cardselection");
                this.KanbanEdit.deleteCard(selected.attr("id"));
            }
    
           }
          </script>
         <script id="Delete" type="text/template">
           <a class="e-customdelete  e-icon" />
         </script>
         <style type="text/css" class="cssStyles">
           .e-customdelete:before {
              content: "\e800";
              line-height: 26px;
              min-height: 26px;
              min-width: 14px;
              display: inline-block;
           }
         </style>
    Also when you use `UrlAdaptor`, you need to return the data as JSON and the JSON object must contain a properties result & count. The `result` holds the `dataSource` as its value and `count` holds the total cards count as its value. The following code example describes the above behavior.
    public ActionResult GetData(Syncfusion.JavaScript.DataManager value)
           {
               var DataSource = db.Tasks.ToList();
               DataResult result1 = new DataResult();
               DataOperations operation = new DataOperations();
               result1.result = DataSource;
               result1.count = DataSource.AsQueryable().Count();
               if (value.Skip > 0)
                   result1.result = operation.PerformSkip(result1.result, value.Skip);
               if (value.Take > 0)
                   result1.result = operation.PerformTake(result1.result, value.Take);
               return Json(result1, JsonRequestBehavior.AllowGet);
           }
        public class DataResult
        {
            public IEnumerable result { get; set; }
            public int count { get; set; }
        }

    Please refer to the below screenshot.

    URL adaptor in ASP NET MVC kanban control

    Using DataOperations helper class you can perform Kanban action at server side. The in-built methods that we have provided in the DataOperations class are listed below.

    1. PerformTake
    2. PerformSelect
    3. Execute

    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, Remove, Crud Update(Multiple cards data will be passed to the server when drag and drop enabled with priority.) Changed values, Added values, Deleted value public ActionResult Crud(List `changed`, List `added`, List `deleted`) </td> </tr> </table> ### Insert Card Using `CrudURL` 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 Crud(List<Task> changed, List<Task> `added`, List<Task> deleted)
            {
                // Insert card in the database.
                if (added != null && added.Count() > 0)
                {
                    foreach (var temp in added)
                    {
                        db.Tasks.Add(temp);
                    }
                }

                    {
                        Task old = db.Tasks.Where(o => o.Id == temp.Id).SingleOrDefault();
                        if (old != null)
                        {
                            db.Entry(old).CurrentValues.SetValues(temp);
