DevExtreme jQuery - 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.
jQuery
JavaScript
function registerKeyHandlers () {
let 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
],
// ...
