OnBitmapScalingModeChanged Method (ImageViewer)

protected virtual void OnBitmapScalingModeChanged( 
   RoutedPropertyChangedEventArgs<BitmapScalingMode> e
)

'Declaration
 
Protected Overridable Sub OnBitmapScalingModeChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of BitmapScalingMode) _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As RoutedPropertyChangedEventArgs(Of BitmapScalingMode)
 
instance.OnBitmapScalingModeChanged(e)

protected:
virtual void OnBitmapScalingModeChanged( 
   RoutedPropertyChangedEventArgs<BitmapScalingMode>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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