)
'Declaration

   ByVal e As RoutedPropertyChangedEventArgs(Of ImageSource) _
) 
'Usage
 
Dim instance As RasterImageBox
Dim e As RoutedPropertyChangedEventArgs(Of ImageSource)
 
instance.OnSourceChanged(e)

            

            
protected:
void OnSourceChanged( 
   RoutedPropertyChangedEventArgs<ImageSource^>^ e
) override 

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.
Remarks

Raising an event invokes the event handler through a delegate.

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