DevExtreme Angular - Keyboard Support

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

Key Action
Enter or Space Changes the widget value.
Changes the switch state to "On".
Changes the switch state to "Off".

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

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