Override this to hook up functionality to the AssociatedObject.

Called when the action is getting detached from its AssociatedObject, but before it has actually occurred.

Override this to unhook functionality from the AssociatedObject.

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.

A VisualStateGroup that can use FluidLayout or not.

Visibility is shadowed by a custom attached property at runtime.

A VisualStateGroup keeps a list of these original values in an attached property.

OriginalValueRecord remembers the original value of a property that was changed in a state.

This enumerated type indicates whether a FluidMoveBehavior applies to the element to which it is attached, or to the children of that element. "Self" is useful when there is a single element that should behave in a special manner; "Children" is useful when the same behavior should apply to all children of a WrapPanel or to the ItemsHost panel of an ItemsControl.
