Repeater 嵌套使用

页面代码：

<asp:Repeater ID="Repeater1" runat="server">
       <itemtemplate>
       <table>
       <tr>
        <%# DataBinder.Eval(Container.DataItem, "c_name") %><br>
        <asp:Repeater ID="Repeater2" runat="server">
         <itemtemplate>
          <a href='Article_Detile.aspx?Id=<%# DataBinder.Eval(Container.DataItem, "a_id") %>'>
           <%# DataBinder.Eval(Container.DataItem, "a_title") %><br>
          </a>
         </itemtemplate>
        </asp:Repeater>
       </tr>
       </table>
       </itemtemplate>
      </asp:Repeater>

后台程序：

public void loadclassdata()
{
  string connstr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = '" +
    Server.MapPath("../DataBase/DB.mdb") + "'";
  string commstr = "select * from tb_class";

  OleDbConnection conn = new OleDbConnection(connstr);
  OleDbCommand comm = new OleDbCommand(commstr, conn);

  DataSet myds = new DataSet();

  OleDbDataAdapter myadapter = new OleDbDataAdapter(comm);

  try
  {
    myadapter.Fill(myds, "tb_class");
    this.Repeater1.DataSource = myds.Tables["tb_class"].DefaultView;
    this.Repeater1.DataBind();
  }
  catch (Exception ex)
  {
    Response.Write(ex.Message);
  }
  finally{

  }
}

private void Repeater1_ItemCreated(object sender,
  System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
  object cid;
  cid = DataBinder.Eval(e.Item.DataItem, "c_id");
  Repeater Repeater2;
  Repeater2 = (Repeater)e.Item.FindControl("Repeater2");
  string connstr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = '" +
    Server.MapPath("../DataBase/DB.mdb") + "'";
  string commstr = "select * from tb_article";
  OleDbConnection conn = new OleDbConnection(connstr);
  OleDbCommand cmd = new OleDbCommand(commstr, conn);
  OleDbDataAdapter da = new OleDbDataAdapter(cmd);
  DataSet ds = new DataSet();
  da.Fill(ds, "tb_article");
  Repeater2.DataSource = ds.Tables["tb_article"].DefaultView;
  Repeater2.DataBind();
}
