Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.
Remarks

Raising an event invokes the event handler through a delegate.

The OnFirstPointChanged 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 OnFirstPointChanged in a derived class, be sure to call the base class's OnFirstPointChanged method so that registered delegates receive the event.

Requirements

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
