DataList里套DataGrid，DataBind嘛搞？


答案：这是九婆婆给的方法：
完整的例子：
◆MyGrid.ascx:
<%@ Control Language="c#" AutoEventWireup="false" Codebehind="MyGrid.ascx.cs" Inherits="XsStudio.test.MyGrid" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>
<asp:DataGrid id="DataGrid1" runat="server" ShowHeader="False" AllowPaging="True" PageSize="3"></asp:DataGrid>
◆MyGrid.ascx.cs
namespace test

using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
/// <summary>
///  MyGrid 的摘要说明。
/// </summary>
public class MyGrid : System.Web.UI.UserControl
{
  protected System.Web.UI.WebControls.DataGrid DataGrid1;
  private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
  }
  public void loaddata(string id)
  {
   DataTable dt = new DataTable();
   dt.Columns.Add("SN");
   dt.Columns[0].AutoIncrementSeed=1;
   dt.Columns[0].AutoIncrement = true;
   dt.Columns.Add("AAA");
   dt.Columns.Add("BBB");
   dt.Columns.Add("CCC");
   dt.Rows.Add(new string[]{"1",id,"435689",System.DateTime.Now.ToString()});
   dt.Rows.Add(new string[]{"2",id,"34535",System.DateTime.Now.ToString()});
   dt.Rows.Add(new string[]{"3",id,"4456",System.DateTime.Now.ToString()});
   dt.Rows.Add(new string[]{"4",id,"64563",System.DateTime.Now.ToString()});
   dt.Rows.Add(new string[]{"5",id,"84535",System.DateTime.Now.ToString()});
   this.DataGrid1.DataSource = dt;
   this.DataGrid1.DataBind();
   ViewState[this.ClientID+"_id"] = id;
  }
  private void DataGrid1_PageIndexChanged(object source, DataGridPageChangedEventArgs e)
  {
   this.DataGrid1.CurrentPageIndex = e.NewPageIndex;
   loaddata(ViewState[this.ClientID+"_id"].ToString());
  }
  #region Web 窗体设计器生成的代码
  override protected void OnInit(EventArgs e)
  {
   //
   // CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。
   //
   InitializeComponent();
   base.OnInit(e);
  }
  
  /// <summary>
  ///  设计器支持所需的方法 - 不要使用代码编辑器
  ///  修改此方法的内容。
  /// </summary>
  private void InitializeComponent()
  {
   this.Load += new System.EventHandler(this.Page_Load);
   this.DataGrid1.PageIndexChanged+=new DataGridPageChangedEventHandler(DataGrid1_PageIndexChanged);
  }
  #endregion
 
}
}

这个是我自己搞的：
在aspx文件里，是这样子套的 
<asp:datalist id="DataList1" runat="server" RepeatColumns="3" RepeatDirection="Horiz
