DevExtreme Angular - Keyboard Support

An end user can use the following keys to interact with the widget.

Key Action
← Switches the widget to the previous view.
→ Switches the widget to the next view.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

jQuery
JavaScript
function registerKeyHandlers () {
    let tabPanel =  $("#tabPanelContainer").dxTabPanel("instance");
    tabPanel.registerKeyHandler("backspace", function (e) {
        // The argument "e" contains information on the event
    });
    tabPanel.registerKeyHandler("space", function (e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxTabPanelModule, DxTabPanelComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxTabPanelComponent) tabPanel: DxTabPanelComponent
    ngAfterViewInit () {
        this.tabPanel.instance.registerKeyHandler("backspace", function (e) {
            // The argument "e" contains information on the event
        });
        this.tabPanel.instance.registerKeyHandler("space", function (e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
        // ...
        DxTabPanelModule
    ],
    // ...
})
