TextBox.OnKeyUp Method
May 02, 2013
Called before KeyUp event occurs.
Assembly: System.Windows (in System.Windows.dll)
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 marks the KeyUp event as handled by setting the Handled property of the event data to true.
Notes to InheritorsIf you override the OnKeyUp method, 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 for Windows Phone.
