OnPictureChanged Method (AnnImageObject)

protected virtual void OnPictureChanged( 
   RoutedPropertyChangedEventArgs<AnnPicture> e
)

'Declaration
 
Protected Overridable Sub OnPictureChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of AnnPicture) _
) 

'Usage
 
Dim instance As AnnImageObject
Dim e As RoutedPropertyChangedEventArgs(Of AnnPicture)
 
instance.OnPictureChanged(e)

protected:
virtual void OnPictureChanged( 
   RoutedPropertyChangedEventArgs<AnnPicture^>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

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.
