- sender
- Object
The object that raised the ItemsChanged event.
The data for the event.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnItemsChanged 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 OnItemsChanged(Object, ItemsChangedEventArgs) in a derived class, make sure that you call the base class' OnItemsChanged(Object, ItemsChangedEventArgs) method so that registered delegates receive the event.
