Animatable.GetAnimationBaseValue Method

Returns the non-animated value of the specified DependencyProperty.

Namespace: System.Windows.Media.Animation
Assembly: PresentationCore (in presentationcore.dll)

public Object GetAnimationBaseValue (
	DependencyProperty dp
)
public final Object GetAnimationBaseValue (
	DependencyProperty dp
)
public final function GetAnimationBaseValue (
	dp : DependencyProperty
) : Object
You cannot use methods in XAML.

Parameters

dp

Identifies the property whose base (non-animated) value should be retrieved.

Return Value

The value that would be returned if the specified property were not animated.

If the specified property is not animated, this method returns the same result as GetValue.

To get the non-animated value of an object's animated property, you use the object's GetAnimationBaseValue method. UIElement, Animatable, and ContentElement each have their own implementation.

In the following example, the non-animated values of animated properties are retrieved and displayed.

/*

   This sample shows how to use the 
   Animatable.GetAnimationBaseValue and 
   UIElement.GetAnimationBaseValue methods
   to get the non-animated value of an
   animated Animatable or UIElement.
