在 JScript 中,您可以處理類別所定義的事件,但不可以定義自己的事件。
<object Unloaded="RoutedEventHandler" .../>

Identifier field

UnloadedEvent

Routing strategy

Direct

Delegate

RoutedEventHandler

Direct routed events do not follow a route, they are only handled within the same element on which they are raised. Direct routed events do support other routed event behavior: they support an accessible handlers collection, and can be used as an EventTrigger in a style.

Loaded and Unloaded might both be raised on controls as a result of user-initiated system theme changes. A theme change causes an invalidation of the control template and the contained visual tree, which in turn causes the entire control to unload and reload. Therefore Unloaded cannot be assumed to occur only on navigation away from the page.

Windows Vista、Microsoft Windows XP SP2 和 Windows Server 2003 SP1 支援 Microsoft .NET Framework 3.0。
