INotifyPropertyChanged::PropertyChanged Event
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Occurs when a property value changes.
Assembly: System (in System.dll)
The PropertyChanged event can indicate that all properties on the object have changed by using either nullptr or String::Empty for the PropertyName property of the PropertyChangedEventArgs.
In data binding, raise PropertyChanged on the data source to cause updates to propagate to the target.
