TreeViewItem.OnKeyUp Method

Syntax

'Declaration
Protected Overrides Sub OnKeyUp ( _
    e As KeyEventArgs _
)

protected override void OnKeyUp(
    KeyEventArgs e
)

Remarks

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.

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.
