Command Columns

The DataGrid provides the following command columns:

DevExtreme HTML5 JavaScript DataGrid CommandColumns EditingColumn AdaptiveColumn

Configure a Command Column

All columns are configured in the columns array. Assign a command column's name to the type option and specify the other column options.

The following example shows how to specify the adaptive column's width:

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "adaptive",
            width: 50
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column type="adaptive" [width]="50"></dxi-column>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

If a command column should have custom content, specify the column's cellTemplate and headerCellTemplate:

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "selection",
            cellTemplate: function ($cellElement, cellInfo) {
                // Render custom cell content here
            },
            headerCellTemplate: function ($headerElement, headerInfo) {
                // Render custom header content here
            }
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column
        type="selection"
        cellTemplate="selectionCellTemplate"
        headerCellTemplate="selectionHeaderCellTemplate">
    </dxi-column>
    <div *dxTemplate="let cellInfo of 'selectionCellTemplate'">
        <!-- Declare custom cell content here -->
    </div>
    <div *dxTemplate="let headerInfo of 'selectionHeaderCellTemplate'">
        <!-- Declare custom header content here -->
    </div>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

Reorder Command Columns

Command columns are reordered similarly to regular columns. Refer to the Column Reordering article for more information.

Customize the Editing Column

The editing column appears when editing is allowed. The avaiable editing buttons depend on the editing mode.

The editing column is a type of buttons column. To customize it, set the column's type to "buttons" and specify the other options.

The following articles describe how to customize editing buttons.

Customize Buttons

The column's buttons array allows you to customize the built-in editing buttons. It can contain configuration objects or button names if the buttons should be available but do not need customizations.

In the following code, a CSS class is added to the Save button. The Edit and Delete buttons should also be declared to display them:

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "buttons",
            buttons: [{
                name: "save",
                cssClass: "my-class"
            }, "edit", "delete"]
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column type="buttons">
        <dxi-button
            name="save"
            cssClass="my-class">
        </dxi-button>
        <dxi-button name="edit"></dxi-button>
        <dxi-button name="delete"></dxi-button>
    </dxi-column>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

Hide a Button

Editing buttons' visibility depends on the allowed editing capabilities. For example, the Delete button is visible if users can delete rows. You can configure the editing capabilities in the editing object.

The Edit and Delete buttons can be hidden by omitting them when declaring the buttons array. However, users can still use the keyboard to edit and delete.

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        editing: {
            allowUpdating: true,
            allowDeleting: true
        },
        columns: [{
            type: "buttons",
            buttons: ["edit"] // The Delete button is hidden
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxo-editing
        [allowUpdating]="true"
        [allowDeleting]="true">
    </dxo-editing>
    <dxi-column type="buttons">
        <dxi-button name="edit"></dxi-button>
    </dxi-column>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

You can hide an editing button or disable editing capabilities for specific rows. Use functions to specify the button's visible option or the editing.allowUpdating/allowDeleting option. Refer to the options' descriptions for examples.

Add a Custom Button

Add an object to the buttons array and specify the button's options in it...

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "buttons",
            buttons: ["edit", "delete", {
                text: "My Command",
                icon: "/url/to/my/icon.ico",
                hint: "My Command",
                onClick: function (e) {
                    // Execute your command here
                }
            }]
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column type="buttons">
        <dxi-button name="edit"></dxi-button>
        <dxi-button name="delete"></dxi-button>
        <dxi-button
            text="My Command"
            icon="/url/to/my/icon.ico"
            hint="My Command"
            (onClick)="myCommand($event)">
        </dxi-button>
    </dxi-column>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    myCommand (e) {
        // Execute your command here
    }
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

... or render the button with custom appearance using a template:

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "buttons",
            buttons: ["edit", "delete", {
                template: function (e) {
                    // Render a custom control here
                }
            }]
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column type="buttons">
        <dxi-button name="edit"></dxi-button>
        <dxi-button name="delete"></dxi-button>
        <dxi-button
            template="myCommandTemplate">
        </dxi-button>
    </dxi-column>
    <div *dxTemplate="let cellInfo of 'myCommandTemplate'">
        <!-- Declare a custom control here -->
    </div>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})

Create a Custom Command Column

The following code shows how to add a command column with custom buttons. Note that the editing column should be declared explicitly because a custom command column replaces it.

jQuery
JavaScript
$(function () {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            type: "buttons",
            buttons: ["edit", "delete"]
        }, 
        "firstName",
        "lastName", {
            type: "buttons",
            buttons: [
                // Declare and configure custom buttons here
            ]
        }]
    });
});
Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column type="buttons" [buttons]="['edit', 'delete']"></dxi-column>
    <dxi-column dataField="firstName"></dxi-column>
    <dxi-column dataField="lastName"></dxi-column>
    <dxi-column type="buttons">
        <dxi-button ... ></dxi-button>
        <!-- Declare and configure custom buttons here -->
    </dxi-column>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})
