Occurs when this object is no longer connected to the main object tree.
Assembly: System.Windows (in System.Windows.dll)
Use a handler based on RoutedEventHandler to handle this event.
When an object is removed from the main object tree, it is no longer displayed in Silverlight client UI. This can be an appropriate time to remove references that the object makes to other resources. For example, connections that the object makes to Web services might currently be closed.
is raised asynchronously versus the object tree change.
Despite being raised asynchronously, the order in which events are raised from within a contiguous subtree of objects is consistent. events are raised top-down and in the order of placement of peer objects in the run time object tree. The top or root of the subtree raises the first event. The first child element of the root raises the next event, and then any children and so on. After returning to any level of the object tree where there are peers that have not yet raised the event, that branch's subroot raises and is traversed, and so on.
Although the event data uses RoutedEventArgs, is not a routed event in Silverlight.
is not raised for any object if the Silverlight application shuts down for any reason. This includes cases where the browser host application or out-of-browser window is closed by the user.
Objects that are being reparented but still remain in the main object tree in the end representation will raise and then Loaded. This is the case for all objects in a subtree, if a subtree is reparented.
Visibility being set to Visibility..::..Collapsed is not equivalent to being unloaded from the object tree, and does not raise on an object. Similarly, changing the open state of a Popup does not raise on the Popup or any of its child elements.
Silverlight 3: This event is not available in Silverlight 3.
