DevExtreme React - 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.
jQuery
JavaScript
function registerKeyHandlers () { let scrollView = $("#scrollViewContainer").dxScrollView("instance"); scrollView.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); scrollView.registerKeyHandler("space", function (e) { // ... }); }
Angular
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 ], // ... })
