Control.OnKeyUp Method

Silverlight

Called before the KeyUp event occurs.

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

protected virtual void OnKeyUp(
	KeyEventArgs e
)

Parameters

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

The OnKeyUp method is called before any event handler for the KeyUp event 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 (the Handled property) of the KeyUp event data.

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 Handled the property, see Events Overview for Silverlight.
