Silverlight 2.0 中，DataGrid得到模板列中的按钮，并得到所点击的行号和键值 以及 实体对象

通过Tag属性可以设置自定义的数据:

（1）借助LoadingRow事件，在初始化DataGrid过程中 使用GetCellContent方法，它可以到单元格内的控件。这时，你也就可以得到你点击的是哪一行了，你可以选择将适当的信息赋给该行的Button的Tag属性; 然后在单击button 按钮时，就可以对该信息进行读取和使用了：

（2）如果你不关心在某一行，而很需要得到改行绑定的实体。那么，你可以在定义Button的时候，将Button的Tag属性直接进行空绑定,可以将该该行绑定的实体对象赋值给Tag，那么在单击Button时，就可以直接使用该对象了。

这样，点击的操作就很灵活了，也可以解决很多问题了。

XAML 脚本：

后置代码：

public partial class Page : UserControl
{
public Page()
{
InitializeComponent();
gridDataList.ItemsSource = Customer.GetSampleCustomerList();
}

private void DataGrid_LoadingRow(object sender,DataGridRowEventArgs e)
{
Customer bindData = (Customer)e.Row.DataContext;
Button btn = gridDataList.Columns[3].GetCellContent(e.Row).FindName("Button") as Button;
btn.Content = bindData.Name;
//btn.Tag = bindData.Index + "," + e.Row.GetIndex();
}

private void Button_Click(object sender,RoutedEventArgs e)
{
Button b = sender as Button;
Customer c = b.Tag as Customer;

msg.Text = "你选择" + c.Name + "的Index是：" + c.Index + ",它位于 DataGrid 的第 " + c.Index + " 行";
//string[] t = b.Tag.ToString().Split(',');
//msg.Text = "你选择的值是：" + t[0] + " 是 DataGrid 的第 " + t[1] + " 行";
}
}

/// < summary >
/// 数据对象
/// </ summary >
public class Customer
{
public Int32 Index { get; set; }
public String Name { get; set; }
public String Address { get; set; }

public Customer(Int32 indexName,String userName,String address)
{
this.Index = indexName;
this.Name = userName;
this.Address = address;
}

public static List < Customer > GetSampleCustomerList()
{
//示例数据
List < Customer > data = new List < Customer > ();
for (int i = 0; i < 10 ; i++) { data.Add(new Customer(i * i,"Jack 之" + i.ToString(),"地址之" + i.ToString())); } return data; } }
