ToolBar.OnKeyDown Method

Provides class handling for the KeyDown routed event that occurs when a key is pressed on an item in the ToolBar.

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

protected override void OnKeyDown(
	KeyEventArgs e
)
You cannot use methods in XAML.

Parameters

e
Type: System.Windows.Input.KeyEventArgs

The arguments for the KeyDown event.

When the user presses HOME, the first item in the ToolBar receives keyboard focus. When the user presses END, the last item in the ToolBar receives keyboard focus. When this occurs, this implementation marks the KeyDown event as handled by setting the Handled property of the event data to true.

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.
