DevExtreme Angular - Keyboard Support

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

Value Picker Key Action
All Alt + ↓ / Alt + ↑ Opens/closes the value picker.
Esc Closes the date/time picker.
Calendar ← → ↑ ↓ Moves focus to the day nearby.
Page Up or Ctrl + ← Displays the previous month.
Page Down or Ctrl + → Displays the next month.
Enter Selects the focused day.
List ↑ / ↓ Moves focus to the previous/next time value.
Enter Selects the focused time value.

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

jQuery
JavaScript
function registerKeyHandlers () {
    let dateBox =  $("#dateBoxContainer").dxDateBox("instance");
    dateBox.registerKeyHandler("backspace", function (e) {
        // The argument "e" contains information on the event
    });
    dateBox.registerKeyHandler("space", function (e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core";
import { DxDateBoxModule, DxDateBoxComponent } from "devextreme-angular";
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxDateBoxComponent, { static: false }) dateBox: DxDateBoxComponent
    // Prior to Angular 8
    // @ViewChild(DxDateBoxComponent) dateBox: DxDateBoxComponent
    ngAfterViewInit () {
        this.dateBox.instance.registerKeyHandler("backspace", function (e) {
            // The argument "e" contains information on the event
        });
        this.dateBox.instance.registerKeyHandler("space", function (e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
        // ...
        DxDateBoxModule
    ],
    // ...
})
