DevExtreme Angular - Keyboard Support

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

Key Action
← Moves focus to the previous item.
→ Moves focus to the next item.

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

TypeScript
  • import { ..., ViewChild, AfterViewInit } from "@angular/core";
  • import { DxNavBarModule, DxNavBarComponent } from "devextreme-angular";
  • // ...
  • export class AppComponent implements AfterViewInit {
  •     @ViewChild(DxNavBarComponent, { static: false }) navBar: DxNavBarComponent
  •     // Prior to Angular 8
  •     // @ViewChild(DxNavBarComponent) navBar: DxNavBarComponent
  •     ngAfterViewInit () {
  •         this.navBar.instance.registerKeyHandler("backspace", function (e) {
  •             // The argument "e" contains information on the event
  •         });
  •         this.navBar.instance.registerKeyHandler("space", function (e) {
  •             // ...
  •         });
  •     }
  • }
  • @NgModule({
  •     imports: [
  •         // ...
  •         DxNavBarModule
  •     ],
  •     // ...
  • })
