[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets the identifier for the dependency property where the value change occurred.
Assembly: System.Windows (in System.Windows.dll)
Property Value
Type: System.Windows.DependencyPropertyThe identifier field of the dependency property where the value change occurred.
If the action of your PropertyChangedCallback changes the property value again, you can use SetValue, passing Property for the dp parameter and using this in the callback scope as the invoking DependencyObject.
The Property can be particularly relevant if used within a common PropertyChangedCallback that is registered for several properties, and it is necessary to disambiguate which property change invoked the callback.
