DevExtreme Angular - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Shift + Mouse Wheel | Scrolls the content left/right if the direction option 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.
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
- ],
- // ...
- })
