一般我们在silverlight中点击右键会出现如下的对话筐.
在flash中 其提供了一个可定制话的右键菜单系统.( ContextMenu)
这个在silverlight中也是一样可以做到的.
过程如下:
1.添加一个<TextBlock>到Page.xaml中
<
asp:Silverlight
ID
="Silverlight1"
runat
="server"
Height
="480px"
MinimumVersion
="2.0.30523"
Source
="~/ClientBin/rightClick.xap"
Windowless
="true"
Width
="640px"
/>
3.最后修改Page.xaml.cs页面的代码
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Net;

System.Windows;
using
System.Windows.Controls;

using
System.Windows.Browser;
namespace
rightClick
{
public partial class Page : UserControl
{
ContextMenuInterceptor _cmi = null;
public Page()
{
InitializeComponent();
_cmi = new ContextMenuInterceptor(MyField);
}
}
public class ContextMenuInterceptor
{
TextBlock TextField;
public ContextMenuInterceptor(TextBlock textField)
{
TextField = textField;
HtmlPage.Document.AttachEvent("oncontextmenu", this.OnContextMenu);
}
private void OnContextMenu(object sender, HtmlEventArgs e)
{
TextField.Text = "Right Clicked Blocked at " + e.OffsetX + "," + e.OffsetY;
//Cancels the event if it is cancelable.
e.PreventDefault();
}
}
}

过程如下:
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"

< Grid x:Name ="LayoutRoot" Background ="White" >
< TextBlock x:Name ="MyField" > Right click please. </ TextBlock >
</ Grid >

2.在页面中设置silverlight的参数Windowless="true"
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 >
<
asp:Silverlight

/>
<
object
data

height
="100%"
>
< param name ="source" value ="ClientBin/rightClick.xap" />
< param name ="onerror" value ="onSilverlightError" />
< param name ="background" value ="white" />

< img src ="http://go.microsoft.com/fwlink/?LinkId=108181" alt ="Get Microsoft Silverlight" style ="border-style: none" />
</ 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.;)
