Comments
The OnItemReleased method raises the ItemReleased event.
Raising an event invokes the event handler through a delegate.
The OnItemReleased 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.
When overriding OnItemReleased in a derived class, make sure to call the base class's OnItemReleased method so that registered delegates receive the event.
