GetAnimationBaseValue Method

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
)

Parameters

dp
Type: System.Windows.DependencyProperty

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

Return Value

Type: System.Object
The value that would be returned if the specified property were not animated.

Implements

IAnimatable.GetAnimationBaseValue(DependencyProperty)

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

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.
