首先看一下效果：

　　 

　　环境：silverlight 4 ，vs2010， windows xp

　　xaml：

<sdk:DataGrid AutoGenerateColumns="False" Height="164" LoadingRow="ResultsGrid_LoadingRow"  
IsReadOnly="True" HorizontalAlignment="Left" Margin="69,70,0,0" 
Name="dataGrid1" VerticalAlignment="Top" Width="205">
            <sdk:DataGrid.Columns>
                <sdk:DataGridTextColumn Header="名称" Width="80" Binding="{Binding Name}"/>
                <sdk:DataGridTextColumn Header="年龄" Width="80" Binding="{Binding Age}"/>
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>

　　cs：

　　定义一个变量 MouseClickManager 类在后面给出

private readonly MouseClickManager _gridClickManager;
 

　　在构造函数中添加响应事件

 _gridClickManager = new MouseClickManager(dataGrid1, 300);
      _gridClickManager.DoubleClick += new System.Windows.Input.MouseButtonEventHandler(_gridClickManager_DoubleClick);
 

　　对应事件 :

  private void _gridClickManager_DoubleClick(object sender, MouseButtonEventArgs e)
        {
            DataGridSouceClass sc = (DataGridSouceClass)dataGrid1.SelectedItem;
            MessageBox.Show("姓名："+sc.Name+"，年龄："+sc.Age);
        }
        private void ResultsGrid_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.MouseLeftButtonUp += _gridClickManager.HandleClick;
        }

 

　　给DataGrid绑定数据：

　　定义一个类：

     public class DataGridSouceClass
          {
                public string Name { get; set; }
                public int Age { get; set; }
          }
 

　　添加数据：

  List<DataGridSouceClass> ls = new List<DataGridSouceClass>();
            DataGridSouceClass dc = new DataGridSouceClass();
            dc.Age = 12;
            dc.Name = "阿斌";
            ls.Add(dc);
            dataGrid1.ItemsSource = ls;

　　运行基本ok !

　　MouseClickManager 类，是网上的人写的。具体是那点看到的，我不记得地址了，实在抱歉。
