Calendar.OnKeyDown Method

Provides class handling for the KeyDown routed event that occurs when the user presses a key while this control has focus.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

abstract OnKeyDown : 
        e:KeyEventArgs -> unit 
override OnKeyDown : 
        e:KeyEventArgs -> unit 

Parameters

e
Type: System.Windows.Input.KeyEventArgs
The data for the event.

Calendar overrides the OnKeyDown method to support keyboard navigation. For more information, see the Calendar class. This implementation marks the KeyDown event as handled by setting the Handled property of the event data to true when a keystroke, such as pressing an ARROW key, performs a navigation action.

Notes to Inheritors

If you override OnKeyDown, always call the base implementation in your OnKeyDown implementation. Failure to call the base implementation prevents base classes from handling the event with a class handler, which might change the run-time behavior of the final class. You can call the base implementation either before or after your special handling, depending on your requirements.
