Activate calendar using keyboard

[Cuong]

Hi,

I'm trying to find a way to activate the calendar of a RadDateTimePicker control and show the popup using the keyboard instead of using the mouse.  What I would like is to activate the popup when the user performs a key combination of ctrl+L or ctrl+?.  How would I go about doing this?

Hello Cuong,

Thank you for contacting us. 

The default shortcut to show the calendar of RadDateTimePicker is functional key F4. If you need to add another shortcut, you can subscribe to KeyDown event and show the calendar. Please take a look at the following code example: 

//subscribe to KeyDown event
this.radDateTimePicker1.KeyDown += radDateTimePicker1_KeyDown;

//show calendar
void radDateTimePicker1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Modifiers == Keys.Control && e.KeyCode == Keys.L)
    {
        RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
        if (calendarBehavior != null)
        {
            calendarBehavior.ShowDropDown();
        }
    }
}

Should you have further questions, I would be glad to help.
