简单的定义下面的路由事件类，死东西，敲熟练

public class MyRoutedEvents : UIElement    {        public static readonly RoutedEvent ButtonClickEvent = EventManager.RegisterRoutedEvent("ButtonClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyRoutedEvents));        public event RoutedEventHandler ButtonClick        {            add { AddHandler(ButtonClickEvent, value); }            remove { RemoveHandler(ButtonClickEvent, value); }        }        public void SendEvent(RoutedEvent evt, RoutedEventArgs e)        {            e.RoutedEvent = evt;            RaiseEvent(e);        }        public virtual void OnButtonClick()        {            SendEvent(ButtonClickEvent, new RoutedEventArgs());        }    }

前台需要一个控件的事件来激活

private void img__MouseLeftButtonDown(object sender, MouseButtonEventArgs e)        {            MyRoutedEvents routed = new MyRoutedEvents();            routed.ButtonClick += new RoutedEventHandler((object sender2, RoutedEventArgs evte) => {                MessageBox.Show("Clicked me.");            });            routed.OnButtonClick();        }

ok了。
