silverlight DataGrid 模拟实现双击行事件

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。
