ASP.NET C# DataGrid里如何实现删除

我想在DataGrid里点一下删除就能删除一行
但是点完之后没有反映……
求人帮忙解决
先谢谢了


附上代码：
public void MyDataGrid_Delete(Object sender, DataGridCommandEventArgs e)
        {
            //建立数据库连接
            OleDbConnection myConnection = new OleDbConnection("Provider=sqloledb;server=(local);database=information;uid=sa;pwd=sa");
            //定义删除SQL语句
            String deleteCmd = "delete from Content where id = @id";
            OleDbCommand myCommand = new OleDbCommand(deleteCmd, myConnection);
            myCommand.Parameters.Add(new OleDbParameter("@id", OleDbType.Char, 11));
            myCommand.Parameters["@id"].Value = MyList.DataKeys[(int)e.Item.ItemIndex];

            myCommand.Connection.Open();

            try
            {
                myCommand.ExecuteNonQuery();

            }
            catch (OleDbException)
            {

            }

            myCommand.Connection.Close();
            //重新绑定数据,并显示
            DataBind();
        }
