OnActiveItemChanged Method

Summary

Raises the ActiveItemChanged event.

Syntax
C#

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

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.
