DevExtreme Angular - Keyboard Support

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

Key Action
↑ / ↓ Moves focus to the previous/next item.
Page Up / Page Down Moves focus to the item located a screen above/below the current one.
Home / End Moves focus to the first/last item.
Enter or Space Selects the focused item.
Shift + ↑ / ↓ Shifts the focused item one item up/down. Active if the allowItemReordering option is set to true.
Delete Removes the focused item. Active if the allowItemDeleting option is set to true.

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

TypeScript
  • import { ..., ViewChild, AfterViewInit } from "@angular/core";
  • import { DxListModule, DxListComponent } from "devextreme-angular";
  • // ...
  • export class AppComponent implements AfterViewInit {
  • @ViewChild(DxListComponent) list: DxListComponent
  • ngAfterViewInit () {
  • this.list.instance.registerKeyHandler("backspace", function (e) {
  • // The argument "e" contains information on the event
  • });
  • this.list.instance.registerKeyHandler("space", function (e) {
  • // ...
  • });
  • }
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxListModule
  • ],
  • // ...
  • })
