Editing

17 Dec 201824 minutes to read

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

Set editSettings.allowEditing and editSettings.allowAdding property as true to enable editing/inserting respectively. The primary key for the data source should be defined in fields.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 editSettings.editItems property. The field property of editSettings.editItems needs to be mapped with data source fields.

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

The following code example describes the above behavior.

<ej-kanban [dataSource]="kanbanData" keyField="Status" fields.primaryKey="Id" fields.content="Summary" [editSettings.editItems]="editItem" editSettings.allowEditing="true" editSettings.allowAdding="true" [query]="query">
    <e-kanban-columns>
        <e-kanban-column key="Open" headertext="Backlog"></e-kanban-column>
        <e-kanban-column key="InProgress" headertext="In Progress"></e-kanban-column>
        <e-kanban-column key="Close" headertext="Done"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

import { Component } from '@angular/core';
import { NorthwindService } from '../../services/northwind.service';

@Component({
  selector: 'ej-app',
  templateUrl: 'app/components/kanban/default.component.html',
  providers: [NorthwindService]
})
export class DefaultComponent {
  public kanbanData: any;
    constructor(private northwindService: NorthwindService) {
        this.kanbanData = northwindService.getTasks();
        this.query = ej.Query().from('kanbanData').take(20);
        this.editItem = [
            { field: 'Id' },
            { field: 'Status', editType: ej.Kanban.EditingType.Dropdown },
            { field: 'Assignee', editType: ej.Kanban.EditingType.Dropdown },
            { field: 'Estimate', editType: ej.Kanban.EditingType.Numeric, editParams: { decimalPlaces: 2 } },
            { field: 'Summary', editType: ej.Kanban.EditingType.TextArea, editParams: { height: 100, width: 200 } }
        ];
    }
}

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

Kanban Editing

Edit modes

Dialog

Set editSettings.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 editSettings.editMode property you can assign either string value (“dialog”).

The following code example describes the above behavior.

<ej-kanban [dataSource]="kanbanData" keyField="Status" fields.primaryKey="Id" fields.content="Summary" [editSettings.editItems]="editItem" editSettings.allowEditing="true" editSettings.allowAdding="true" [query]="query">
    <e-kanban-columns>
        <e-kanban-column key="Open" headertext="Backlog"></e-kanban-column>
        <e-kanban-column key="InProgress" headertext="In Progress"></e-kanban-column>
        <e-kanban-column key="Close" headertext="Done"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

            { field: 'Id' },
            { field: 'Status', editType: ej.Kanban.EditingType.Dropdown },
            { field: 'Assignee', editType: ej.Kanban.EditingType.Dropdown },
            { field: 'Estimate', editType: ej.Kanban.EditingType.Numeric, editParams: { decimalPlaces: 2 } },
            { field: 'Summary', editType: ej.Kanban.EditingType.TextArea }
        ];
    }
}

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

Edit Mode as Dialog

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

value attribute is used to bind the corresponding field value while editing.

name attribute is used to get the changed field values while save the edited card.

For editMode property you can assign string value dialogTemplate.

The following code example describes the above behavior.

Place the ng-template in the “index.html” page.

<script id="template" type="text/ng-template">
                        <table cellspacing="10">

External Template Form

Cell edit type and its params

The edit type of bound column can be customized using editType property of editItems. The following Essential JavaScript controls are supported built-in by editType. And also you can define the model for all the edit types controls while editing through editParams property of editItems.

The following table describes editType and their corresponding editParams of the specific data type of the column.

EditType	EditParams	Description	Example
Numeric	ejTextBoxes	control for integers, double, and decimal data’s	editParams: { decimalPlaces: 2}
String	HTML Textbox	HTML Textbox	-
DatePicker	ejDatePicker	control for date data	editParams: { buttonText : "Now" }
DateTimePicker	ejDateTimePicker	control for date data-time data	editParams: { enabled: true }
DropDown	ejDropDownList	control for list of data	editParams: { allowGrouping: true }
RTE	ejRTE	control for customizing text in RTE format	editParams: { allowResize: true }
TextArea	HTML TextArea	Control for multi-line plain-text editing	editParams:{height:100,width:200}

NOTE

If editType is not set, then by default it will display HTML textbox while editing a card.

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.

<ej-kanban [dataSource]="kanbanData" keyField="Status" fields.primaryKey="Id" fields.content="Summary" [editSettings.editItems]="editItem" editSettings.allowEditing="true" editSettings.allowAdding="true" [query]="query">
    <e-kanban-columns>
        <e-kanban-column key="Open" headerText="Backlog"></e-kanban-column>
        <e-kanban-column key="InProgress" headerText="In Progress"></e-kanban-column>
        <e-kanban-column key="Close" headerText="Done"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

import { Component } from '@angular/core';
import { NorthwindService } from '../../services/northwind.service';

@Component({
  selector: 'ej-app',
  templateUrl: 'app/components/kanban/default.component.html',
  providers: [NorthwindService]
})
export class DefaultComponent {
  public kanbanData: any;
    constructor(private northwindService: NorthwindService) {
        this.kanbanData = northwindService.getTasks();
        this.query = ej.Query().from('kanbanData').take(30);
        this.editItem = [
            { field: "Id" },
            { field: "Status", editType: ej.Kanban.EditingType.Dropdown },
            { field: "Estimate", editType: ej.Kanban.EditingType.Numeric, editParams: { decimalPlaces: 2 } },
            { field: "Summary", editType: ej.Kanban.EditingType.RTE, editParams: { height: 150, minHeight: 100 } }
        ];
    }
}

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.

jquery.validate.min.js
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

        <e-kanban-column key="Close" headerText="Done"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

        this.kanbanData = northwindService.getTasks();
        this.query = ej.Query().from('kanbanData').take(30);
        this.editItem = [
            { field: "Id" },
            { field: "Status", editType: ej.Kanban.EditingType.String },
            { field: "Assignee", editType: ej.Kanban.EditingType.Dropdown },
            { field: "Estimate", editType: ej.Kanban.EditingType.Numeric, editParams: { decimalPlaces: 2 }, validationRules: { range: [0, 1000] } },
            { field: "Summary", editType: ej.Kanban.EditingType.TextArea, validationRules: { required: true } }
        ];
