PropertyChangedCallback Delegate

.NET Framework 4.5

Represents the callback that is invoked when the effective property value of a dependency property changes.

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

public delegate void PropertyChangedCallback(
	DependencyObject d,
	DependencyPropertyChangedEventArgs e
)

Parameters

d: Type: System.Windows.DependencyObject
The DependencyObject on which the property has changed value.

e: Type: System.Windows.DependencyPropertyChangedEventArgs
Event data that is issued by any event that tracks changes to the effective value of this property.

The following example registers a new dependency property, using the signature that specifies a PropertyChangedCallback. The PropertyChangedCallback is used to create a callback that changes an internal property whenever the public property changes.

public static readonly DependencyProperty AquariumGraphicProperty = DependencyProperty.Register(
  "AquariumGraphic",
  typeof(Uri),
  typeof(AquariumObject),
  new FrameworkPropertyMetadata(null,
      FrameworkPropertyMetadataOptions.AffectsRender, 
      new PropertyChangedCallback(OnUriChanged)
  )
);

private static void OnUriChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) {
  Shape sh = (Shape) d;
  sh.Fill = new ImageBrush(new BitmapImage((Uri)e.NewValue));
}
