Occurs when the items list of the collection has changed, or the collection is reset.
Assembly: System.Windows (in System.Windows.dll)
Raise this event whenever your collection processes calls to typical collection members (Add, Remove, Insert, etc.).
The event data of this event (NotifyCollectionChangedEventArgs) reports information about the nature of the collection change.
This interface does not report changes to the individual properties of any objects that are contained in the collection, only changes that have occurred at the collection level. To report changes to properties using data binding at the object level, use INotifyPropertyChanged.
