Summary

Syntax

C++

   EventArgs e 
)

   ByVal e As System.EventArgs 
)

protected:  
   virtual void OnActiveItemChanged( 
      System::EventArgs^ e 
   )

Parameters

Event data

Remarks

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