Angular Popup - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
↑ → ↓ ← | Drags the popup when it is focused and dragEnabled is true. |
Esc | Closes the popup. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
TypeScript
- import { ..., ViewChild, AfterViewInit } from '@angular/core';
- import { DxPopupModule, DxPopupComponent } from 'devextreme-angular';
- // ...
- export class AppComponent implements AfterViewInit {
- @ViewChild(DxPopupComponent, { static: false }) popup: DxPopupComponent;
- // Prior to Angular 8
- // @ViewChild(DxPopupComponent) popup: DxPopupComponent;
- ngAfterViewInit () {
- this.popup.instance.registerKeyHandler('backspace', function(e) {
- // The argument "e" contains information on the event
- });
- this.popup.instance.registerKeyHandler('space', function(e) {
- // ...
- });
- }
- }
- @NgModule({
- imports: [
- // ...
- DxPopupModule
- ],
- // ...
- })
