Triggers, EventTrigger, Actions and BeginStoryboard are not commonly used. These API mainly exist for compatibility in XAML originally used for Microsoft Silverlight. For most scenarios where event triggers were used previously, you should either use visual states, or start animations by writing a Loaded handler that looks up an animation in page-level resources and then calls Begin on the animation's main Storyboard. For more info, see Quickstart: Control templates or Storyboarded animations.
Dispatcher |
Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject) |
Clear |
Clears the local value of a dependency property. (Inherited from DependencyObject) |
Get |
Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject) |
Get |
Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject) |
Read |
Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject) |
Register |
Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject) |
Set |
Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject) |
Unregister |
Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject) |
