WPF自定义RoutedEvent事件示例代码

*************************
引用网友，便于查找所用.....
创建自定义路由事件和应用分为6个步骤：
(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);
}
5.1 Xaml访问自定义控件与引用自定义事件
<local:MyObject Width="80" Height="25" Background="Blue" MyObjectAutoSNHandler="MyObject_MyObjectAutoSNHandler" />
5.2 通过代码方式，添加监听路由事件
this.ContainerName.AddHandler(MyObject.MyObjectRoutedEvent, new RoutedEventHandler(MyObject_MyObjectAutoSNHandler));
6.事件处理behindcode
void MyObject_MyObjectAutoSNHandler(object sender, MyObjectRoutedEventArgs e)
{
      string sn=e.SerialNumber;
}
 
 
*************************
public static readonly DependencyProperty PageIndexProperty =
    DependencyProperty.Register("PageIndex", typeof(int), typeof(MoonPdfPanel), new UIPropertyMetadata(1));
 
public int PageIndex
{
    get {return (int)GetValue(PageIndexProperty);}
    set { SetValue(PageIndexProperty, value); }
}
 
public static readonly RoutedEvent PageIndexChangedEvent = EventManager.RegisterRoutedEvent("PageIndexChanged", RoutingStrategy.Bubble, typeof(RoutedPropertyChangedEventHandler<int>), typeof(MoonPdfPanel));
 
public event RoutedPropertyChangedEventHandler<int> PageIndexChanged
{
    add { AddHandler(PageIndexChangedEvent, value); }
    remove { RemoveHandler(PageIndexChangedEvent, value); }
}
 
// 触发事件，结尾一定要使用RaiseEvent(args)来触发路由事件。
RoutedPropertyChangedEventArgs<int> args =
        new RoutedPropertyChangedEventArgs<int>(
            val, this.GetCurrentPageNumber(), PageIndexChangedEvent);
    this.RaiseEvent(args);
