silverlight右键菜单实现

概述1.添加一个<TextBlock>到Page.xaml中 <UserControl x:Class="rightClick.Page"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    

1.添加一个<TextBlock>到Page.xaml中

<UserControl x:Class="rightClick.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    WIDth="400" Height="300">
    <GrID x:name="LayoutRoot" Background="White">
        <TextBlock x:name="MyFIEld">Right click please.</TextBlock>
   </GrID>
</UserControl>

　　2.在页面中设置silverlight的参数windowless="true"  (这一点是最关键的！！！！！)

        <asp:Silverlight ID="Silverlight1" runat="server" Height="480px"
            MinimumVersion="2.0.30523" Source="~/ClIEntBin/rightClick.xap"
windowless="true" WIDth="640px" />
        <object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" wIDth="100%" height="100%">
            <param name="source" value="ClIEntBin/rightClick.xap"/>
            <param name="onerror" value="onSilverlightError" />
            <param name="background" value="white" />
            <param name="windowless" value="true" />
            <a href="http://go.microsoft.com/fwlink/?linkID=115261" >
                 <img src="http://go.microsoft.com/fwlink/?linkID=108181" alt="Get Microsoft Silverlight" />
            </a>
        </object>

　　3.最后修改Page.xaml.cs页面的代码

　　新建立一个ContextMenuInterceptor类.这个类是用来处理页面中“OnContextMenu”事件的.在用到HTMLPage对象你需要引入System.Window.browser命名空间.

　　在调用e.PeventDefault()方法后,将会取消右键点击事件.所以silverlight不会捕捉到它.

　　在这里我们已经成功的拦截了右键点击事件,做我们想做的任何事情了.;)
