DevExtreme Angular - Keyboard Support

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

All Alt + ↓ / Alt + ↑ Opens/closes the value picker.

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

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