DevExtreme Angular - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
↑ / ↓ | Scrolls the content up/down if the scrolling direction is "vertical" or "both". |
Mouse Wheel + Shift or ← / → | Scrolls the content left/right if the scrolling direction is "horizontal" or "both". |
Page Up / Page Down | Scrolls the content up/down by a whole page. |
Home / End | Scrolls the content to the top/bottom. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
TypeScript
- import { ..., ViewChild, AfterViewInit } from "@angular/core";
- import { DxScrollViewModule, DxScrollViewComponent } from "devextreme-angular";
- // ...
- export class AppComponent implements AfterViewInit {
- @ViewChild(DxScrollViewComponent) scrollView: DxScrollViewComponent
- ngAfterViewInit () {
- this.scrollView.instance.registerKeyHandler("backspace", function (e) {
- // The argument "e" contains information on the event
- });
- this.scrollView.instance.registerKeyHandler("space", function (e) {
- // ...
- });
- }
- }
- @NgModule({
- imports: [
- // ...
- DxScrollViewModule
- ],
- // ...
- })
