OnRenderImage Method

Summary

Raises the RenderImage event.

Syntax

C#
VB
C++
protected virtual void OnRenderImage( 
   ImageViewerRenderEventArgs e 
) 
Protected Overridable Sub OnRenderImage( 
   ByVal e As ImageViewerRenderEventArgs 
) 
protected:  
   virtual void OnRenderImage( 
      ImageViewerRenderEventArgs^ e 
   ) 

Parameters

e

The event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnRenderImage 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.

Note to Inheritors: When overriding OnRenderImage in a derived class, be sure to call the base class's OnRenderImage method so that registered delegates receive the event.
