Keyboard Support

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

Key Action
← → ↑ ↓ 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.
Ctrl + ↑ Increases zoomLevel.
Ctrl + ↓ Decreases zoomLevel.
Home Moves focus to the first date in the view.
End Moves focus to the last date in the view.

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

jQuery
JavaScript
function registerKeyHandlers () {
    const calendar = $("#calendarContainer").dxCalendar("instance");
    calendar.registerKeyHandler("backspace", function(e) {
        // The argument "e" contains information on the event
    });
    calendar.registerKeyHandler("space", function(e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxCalendarModule, DxCalendarComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxCalendarComponent, { static: false }) calendar: DxCalendarComponent;
    // Prior to Angular 8
    // @ViewChild(DxCalendarComponent) calendar: DxCalendarComponent;

    ngAfterViewInit () {
        this.calendar.instance.registerKeyHandler('backspace', function(e) {
            // The argument "e" contains information on the event
        });
        this.calendar.instance.registerKeyHandler('space', function(e) {
            // ...
        });
    }
}
@NgModule({
