OnPictureChanged Method

Summary

Occurs when the value Picture property changes.

Syntax

C#
VB
C++
protected virtual void OnPictureChanged( 
   RoutedPropertyChangedEventArgs<AnnPicture> e 
) 
  
Protected Overridable Sub OnPictureChanged( _ 
   ByVal e As RoutedPropertyChangedEventArgs(Of AnnPicture) _ 
)  
protected: 
virtual void OnPictureChanged(  
   RoutedPropertyChangedEventArgs<AnnPicture^>^ e 
)  

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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