DevExtreme jQuery - Keyboard Support
An end user can use the following keys to interact with the widget.
| Key | Action |
|---|---|
| ↑ / ↓ | Moves focus to the previous/next item. |
| Page Up / Page Down | Moves focus to the item located a screen above/below the current one. |
| Home / End | Moves focus to the first/last item. |
| Enter or Space | Selects the focused item. |
| Shift + ↑ / ↓ | Shifts the focused item one item up/down. Active if the allowItemReordering option is set to true. |
| Delete | Removes the focused item. Active if the allowItemDeleting option is set to true. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () {
let list = $("#listContainer").dxList("instance");
list.registerKeyHandler("backspace", function (e) {
// The argument "e" contains information on the event
});
list.registerKeyHandler("space", function (e) {
// ...
});
}Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core";
import { DxListModule, DxListComponent } from "devextreme-angular";
// ...
export class AppComponent implements AfterViewInit {
@ViewChild(DxListComponent, { static: false }) list: DxListComponent
// Prior to Angular 8
// @ViewChild(DxListComponent) list: DxListComponent
ngAfterViewInit () {
this.list.instance.registerKeyHandler("backspace", function (e) {
// The argument "e" contains information on the event
});
this.list.instance.registerKeyHandler("space", function (e) {
// ...
});
}
}
@NgModule({
imports: [
