OnItemAdded Method

Summary

Raises the ItemAdded event.

Syntax

C++/CLI

protected virtual void OnItemAdded( 
   MedicalViewerCollectionEventArgs<T> e 
)

protected:  
   virtual void OnItemAdded( 
      MedicalViewerCollectionEventArgs<T>^ e 
   )

Parameters

e An MedicalViewerCollectionEventArgs<T> that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

The OnItemAdded 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 OnItemAdded in a derived class, be sure to call the base class OnItemAdded method so that registered delegates receive the event.
