Syntax
public class GoToStateAction : TargetedTriggerAction<FrameworkElement>, IAttachedObject
Remarks

If the TargetName property is set, this action will attempt to change the state of the targeted element. If not, it walks the element tree in an attempt to locate an alternative target that defines states. ControlTemplate and UserControl are two common possibilities.
