Remarks

TriggerAction exists in Silverlight for WPF compatibility. TriggerAction is not intended to be derived from as a base for other trigger implementations; the entire Triggers syntax is a discouraged technique in Silverlight 5. For more information, see Remarks in EventTrigger, or Customizing the Appearance of an Existing Control by Using a ControlTemplate.
