virtual void OnPositionChanged( 
   RoutedPropertyChangedEventArgs<Point>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnPositionChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnPositionChanged in a derived class, be sure to call the base class's OnPositionChanged method so that registered delegates receive the event.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
