Question

WPF中DataGrid如何单击一行，触发一个事件，本人小菜，请详解，写代码

博客园我看了好多，不过都不太懂，没有找到ItemDataBound这个事件，最好XAML和.cs的代码都有，谢谢

using System.Data;
namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DataTable dt = new DataTable();
            dt.Columns.Add("Firstname");
            dt.Columns.Add("Lastname");
            DataRow dr = dt.NewRow();
            dr["Firstname"] = "allen";
            dr["Lastname"] = "coww";
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["Firstname"] = "allen";
            dr["Lastname"] = "coww";
            dt.Rows.Add(dr);
            dg.ItemsSource = dt.DefaultView;
        }
        private void dg_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
        // 选择行，这个事件会被激活
        }
    }
