Expression Studio 4.0
ExtendedVisualStateManager is a custom VisualStateManager that can smooth out the animation of layout properties. With this custom VisualStateManager, states can include changes to properties like Grid.Column, can change element heights to or from Auto, and so on. These changes will be smoothed out over time using the GeneratedDuration and GeneratedEasingFunction of the appropriate transition. See the "VisualStateManager overrides" region below for a general description of the algorithm.
