Remarks
Unlike the BindingsCollection.OnCollectionChanging method, there is no such corresponding method in the GlobalObjectProvider class.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnCollectionChanged 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 OnCollectionChanged in a derived class, be sure to call the base class’s OnCollectionChanged method so that registered delegates receive the event.
