Notifies listeners of dynamic changes to a collection, such as when items are added and removed, or the entire collection object is reset.
(in System.Windows.dll)
Visual Basic (Declaration)
Public Interface INotifyCollectionChanged
Dim instance As INotifyCollectionChanged
public interface INotifyCollectionChanged
INotifyCollectionChanged defines one member, CollectionChanged. The event data of this event (NotifyCollectionChangedEventArgs) reports information about the nature of the collection change.
To provide change notifications for bindings to ItemsControl and its subclasses, your collection must implement this interface. Before implementing your own collection class, consider using the ObservableCollection<(Of <(T>)>) class that implements INotifyCollectionChanged and INotifyPropertyChanged.
