OnViewerChanged Method

Summary

Syntax

C++

protected virtual void OnViewerChanged( 
   EventArgs e 
)

  
Protected Overridable Sub OnViewerChanged( _ 
   ByVal e As EventArgs _ 
)

protected: 
virtual void OnViewerChanged(  
   EventArgs^ e 
)

Parameters

e
An EventArgs that contains the event data.

Remarks

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