Keyboard Support

An end user can use the following keys to interact with the UI component.

Key Action
Shift + Mouse Wheel Scrolls the content left/right if the direction property is "horizontal".
←→↑↓ Moves focus to the neighboring tile.
Home Moves focus to the very first tile.
End Moves focus to the very last tile.
Enter or Space Selects the focused tile.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

jQuery
JavaScript
function registerKeyHandlers () {
    const tileView = $("#tileViewContainer").dxTileView("instance");
    tileView.registerKeyHandler("backspace", function(e) {
        // The argument "e" contains information on the event
    });
    tileView.registerKeyHandler("space", function(e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxTileViewModule, DxTileViewComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxTileViewComponent, { static: false }) tileView: DxTileViewComponent;
    // Prior to Angular 8
    // @ViewChild(DxTileViewComponent) tileView: DxTileViewComponent;

    ngAfterViewInit () {
        this.tileView.instance.registerKeyHandler('backspace', function(e) {
            // The argument "e" contains information on the event
        });
        this.tileView.instance.registerKeyHandler('space', function(e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
        // ...
        DxTileViewModule
    ],
    // ...
})
Vue
