  • Demo Configurator
  • Command keyAlt

This example demonstrates the navigation between dates with the arrow keys into the ASP.NET AJAX Calendar and RadDatePicker controls. The navigation could be enabled with setting the EnableKeyboardNavigation property to true:

<telerik:RadCalendar EnableKeyboardNavigation="true" EnableMultiSelect="false" runat="server" ID="RadCalendar1" />

When the EnableKeyboardNavigation is set to true the user could navigate with:

  • Left arrow - moves one date left form the current date
  • Right arrow - moves one date right from the current date
  • Top arrow - moves one week before the current date
  • Bottom arrow - moves one week after the current date

If the user presses the Enter key or spacebar key the date will be selected.
Note that the EnableMultyDateSelecttion property of the calendar should be set to false.

By default you can use Ctrl + Y to focus the control. With R3 2021 you can now focus the RadCalendar by specifying the FocusKey and CommandKey in the KeyboardNavigationSettings inner tag.
