DependencyPropertyChangedEventArgs.Property Property

Gets the identifier for the dependency property where the value change occurred.

Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)


Public ReadOnly Property Property As DependencyProperty
public DependencyProperty Property { get; }

Property Value

Type: System.Windows.DependencyProperty
The 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.
