WPF基础之路由事件

一、路由事件的声明、注册和属性包装Border

 class ButtonBase:ContentControl
    {
        //1.声明
        public static readonly RoutedEvent ClickEvent;
        //2.注册
        static ButtonBase()
        {
            ButtonBase.ClickEvent = EventManager.RegisterRoutedEvent("Click",RoutingStrategy.Bubble,
                typeof(RoutedEventHandler),typeof(ButtonBase));


        }
        //3.属性包装器
        public event RoutedEventHandler Click
        {
            add
            {
                base.AddHandler(ButtonBase.ClickEvent,value);
            }
            remove
            {
                base.RemoveHandler(ButtonBase.ClickEvent, value);
            }
        }
    }
