OnImageChanged Method (RasterImageViewer)

protected virtual void OnImageChanged( 
   RoutedPropertyChangedEventArgs<RasterImage> e
)

protected:
virtual void OnImageChanged( 
   RoutedPropertyChangedEventArgs<RasterImage^>^ e
) 

'Declaration
 
Protected Overridable Sub OnImageChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of RasterImage) _
) 

'Usage
 
Dim instance As RasterImageViewer
Dim e As RoutedPropertyChangedEventArgs(Of RasterImage)
 
instance.OnImageChanged(e)

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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