The EventTrigger type exposes the following members.
|EventTrigger||Initializes a new instance of the EventTrigger class.|
|Actions||Gets the collection of BeginStoryboard objects that this EventTrigger maintains.|
|Dispatcher||Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)|
|RoutedEvent||Gets or sets the name of the event that initiates the trigger.|
|CheckAccess||Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)|
|ClearValue||Clears the local value of a dependency property. (Inherited from DependencyObject.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetAnimationBaseValue||Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ReadLocalValue||Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)|
|SetValue||Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
EventTrigger and the object.Triggers property element usage on elements are supported by Silverlight, but using this technique is discouraged for current applications. EventTrigger can only support a triggering action for the Loaded event (you name the event in the EventTrigger.RoutedEvent property.) This makes an EventTrigger unsuitable for most run-time interactions. Instead of using EventTrigger and the Triggers property, consider one of the following two alternatives:
For animating properties on objects that are not controls, place the storyboard in the general Resources for a page or application. Then assign an event handler on the element where you would have placed "Triggers". The event handler, when responding to the relevant event, should retrieve the storyboard from the resource dictionary. You then call Begin on the retrieved Storyboard.
For animating properties on objects that are controls (derive from Control), use the VisualStateManager technique, and run the appropriate animations based on state of or inputs to the control by calling GoToState.
