(1)自定义路由事件参数对象
(2)声明并注册路由事件
(3)为路由事件添加CLR事件包装
(4)创建可以激发路由事件的方法
(5)Xaml(behind code引用)
(6)事件处理
public class MyObjectRoutedEventArgs:RoutedEventArgs{
public MyObjectRoutedEventArgs(RoutedEvent routedEvent, object source) : base(routedEvent, source) { }
public DateTime ClickTime { get; set; }
}
public class MyObject:Button{
//注册实例化路由事件,Bubble\Direct\Tunnel
public static readonly RoutedEvent MyObjectRoutedEvent
=EventManager.RegisterRoutedEvent("OnMyObjectClick",RoutingStrategy.Bubble
,typeof(EventHandler<MyObjectRoutedEventArgs>),typeof(MyObject);
//CLR包装
public Event RoutedEventHandler MyObjectAutoSNHandler{
add{this.AddHanler{MyObjectRoutedEvent,value};}
remove{this.RemoveHanler{MyObjectRoutedEvent,value};}}
}
public override OnClick(){
base.OnClick();
MyObjectRoutedEventArgs args=new MyObjectRoutedEventArgs();
args.SerialNumber="生成流水号";
args.Subject="生成主题";
使用RaiseEvent(args)来触发路由事件
this.RaiseEvent(args);
}

DependencyProperty.Register(

RoutedPropertyChangedEventHandler<

// 触发事件,结尾一定要使用RaiseEvent(args)来触发路由事件。
