Provides class handling for the KeyDown routed event that occurs when the user presses a key.
Assembly: PresentationFramework (in PresentationFramework.dll)
This implementation marks the KeyDown event as handled by setting the Handled property of the event data to true when the user presses CTRL+TAB, CTRL+SHIFT+TAB, HOME, or END to navigate between TabItem objects. Otherwise, this implementation does not change the handled state (the Handled property) of the KeyDown event data.Notes to Inheritors
If you override , always call the base implementation in your 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.
