DevExtreme Angular - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
↑ or PageUp | Sets focus to the previous panel. |
↓ or PageDown | Sets focus to the next panel. |
Home | Sets focus to the first panel. |
End | Sets focus to the last panel. |
Enter | Expands the focused panel. |
Space | Collapses the focused panel. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
TypeScript
- import { ..., ViewChild, AfterViewInit } from "@angular/core";
- import { DxAccordionModule, DxAccordionComponent } from "devextreme-angular";
- // ...
- export class AppComponent implements AfterViewInit {
- @ViewChild(DxAccordionComponent) accordion: DxAccordionComponent
- ngAfterViewInit () {
- this.accordion.instance.registerKeyHandler("backspace", function (e) {
- // The argument "e" contains information on the event
- });
- this.accordion.instance.registerKeyHandler("space", function (e) {
- // ...
- });
- }
- }
- @NgModule({
- imports: [
- // ...
- DxAccordionModule
- ],
- // ...
- })
