OnImageSizeChanged Method

protected virtual void OnImageSizeChanged( 
   SizeChangedEventArgs e
)

'Declaration
 
Protected Overridable Sub OnImageSizeChanged( _
   ByVal e As SizeChangedEventArgs _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As SizeChangedEventArgs
 
instance.OnImageSizeChanged(e)

protected:
virtual void OnImageSizeChanged( 
   SizeChangedEventArgs^ e
) 

Parameters

e

A System.Windows.SizeChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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