OnImageHorizontalAlignmentChanged Method

protected virtual void OnImageHorizontalAlignmentChanged( 
   RoutedPropertyChangedEventArgs<HorizontalAlignment> e
)

'Declaration
 
Protected Overridable Sub OnImageHorizontalAlignmentChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of HorizontalAlignment) _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As RoutedPropertyChangedEventArgs(Of HorizontalAlignment)
 
instance.OnImageHorizontalAlignmentChanged(e)

protected:
virtual void OnImageHorizontalAlignmentChanged( 
   RoutedPropertyChangedEventArgs<HorizontalAlignment>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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