TreeView.OnKeyUp Method

Provides handling for the KeyUp event.

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

protected override void OnKeyUp(
	KeyEventArgs e
)

Parameters

e
Type: System.Windows.Input.KeyEventArgs
A KeyEventArgs that contains the event data.

The OnKeyUp method is called before any event handler for the KeyUp is called. This method allows derived classes to handle the KeyUp event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation does not change the handled state of the event.

Notes to Inheritors

If you override OnKeyUp, you can prevent registered delegates from receiving events by setting Handled to true. For more information about routed events and the Handled property, see Events Overview for Silverlight.
