Indicates whether the KeyFrames property should be persisted.
Assembly: PresentationCore (in PresentationCore.dll)
This ShouldSerialize method is provided because the KeyFrames property does not have a simple default value. This method indicates whether the property has changed from its default value. You typically invoke this method if you are either developing a designer for the RectAnimationUsingKeyFrames or developing your own control incorporating the RectAnimationUsingKeyFrames.
