DevExtreme Angular - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Space | Changes the widget value. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
TypeScript
- import { ..., ViewChild, AfterViewInit } from '@angular/core';
- import { DxCheckBoxModule, DxCheckBoxComponent } from 'devextreme-angular';
- // ...
- export class AppComponent implements AfterViewInit {
- @ViewChild(DxCheckBoxComponent, { static: false }) checkBox: DxCheckBoxComponent;
- // Prior to Angular 8
- // @ViewChild(DxCheckBoxComponent) checkBox: DxCheckBoxComponent;
- ngAfterViewInit () {
- this.checkBox.instance.registerKeyHandler('backspace', function(e) {
- // The argument "e" contains information on the event
- });
- this.checkBox.instance.registerKeyHandler('space', function(e) {
- // ...
- });
- }
- }
- @NgModule({
- imports: [
- // ...
- DxCheckBoxModule
- ],
- // ...
- })
