Remarks
The AddingNew event and the AddNew method allow custom-created items to be added to the list.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnAddingNew 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 OnAddingNew(AddingNewEventArgs) in a derived class, be sure to call the base class's OnAddingNew(AddingNewEventArgs) method so that registered delegates receive the event.
