OnPreRender Method

Summary

Raises the PreRender event.

Syntax

C++

protected virtual void OnPreRender( 
   ImageViewerRenderEventArgs e 
)

Protected Overridable Sub OnPreRender( 
   ByVal e As ImageViewerRenderEventArgs 
)

protected:  
   virtual void OnPreRender( 
      ImageViewerRenderEventArgs^ e 
   )

Parameters

The event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnPreRender 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 OnPreRender in a derived class, be sure to call the base class's OnPreRender method so that registered delegates receive the event.
