IAnimatable.GetAnimationBaseValue Method (DependencyProperty)
Retrieves the base value of the specified DependencyProperty object.
Assembly: PresentationCore (in PresentationCore.dll)
Use this method instead of GetValue when you want to retrieve the non-animated value of an animated property. This method takes advantage of the fact that Windows Presentation Foundation (WPF) animations do not remove the target property's original value. For more information, see Dependency Property Value Precedence.
