Raises the CollectionChanged event.
[Visual Basic] Protected Overridable Sub OnCollectionChanged( _ ByVal ccevent As CollectionChangeEventArgs _ ) [C#] protected virtual void OnCollectionChanged( CollectionChangeEventArgs ccevent ); [C++] protected: virtual void OnCollectionChanged( CollectionChangeEventArgs* ccevent ); [JScript] protected function OnCollectionChanged( ccevent : CollectionChangeEventArgs );
- A CollectionChangeEventArgs that contains the event data.
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.
