注解

这是一个附加事件。This is an attached event. WPFWPF将附加事件作为路由事件实现。implements attached events as routed events. 附加事件本质上是XAMLXAML一种用于引用事件的语言概念, 这些事件可在未定义该事件的对象WPFWPF上进行处理, 后者通过同时启用事件来遍历路由。Attached events are fundamentally a XAMLXAML language concept for referencing events that can be handled on objects that do not define that event, which WPFWPF expands upon by also enabling the event to traverse a route. 附加事件在代码中没有直接处理语法;若要在代码中附加路由事件的处理程序, 请使用指定的 Add * 处理程序方法。Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, you use a designated Add*Handler method. 有关详细信息, 请参阅附加事件概述For details, see Attached Events Overview.
