DataGrid中嵌套使用Repeater

本文描述了如何把Repeater 控件嵌套进DataGrid来显示分级的数据。当然，你也可以将这一技术应用到其他的列表绑定控件上去，比如DataGrid包含DataGrid，DataList包含DataList等等的组合。

完整的代码如下，要注意的是,

   DataGrid1.DataSource=dv;
    DataGrid1.DataBind();

一定要在ds.Relations.Add(..)之后..

<%@import namespace="System.Data" %>
<%@import namespace="System.Data.OleDb"%>
<script language="c#" runat="server">
string connstr=ConfigurationSettings.AppSettings["ConnectionString"];

//小区信息
string sql="select * from location where location_id in(select location from catalyst)";
//交换机信息
string sqltext="select * from catalyst order by location desc";

private void page_load(Object obj,EventArgs e)
{
  if(!Page.IsPostBack)
   {
     Dataload();
   }
}

private void Dataload()
{
     try
  {
    OleDbConnection conn=new  OleDbConnection(connstr);
    DataSet ds=new DataSet();
    OleDbDataAdapter da=new OleDbDataAdapter(sql,conn);
    da.Fill(ds,"location");
    DataView dv=new DataView(ds.Tables["location"]);

    OleDbDataAdapter da2=new OleDbDataAdapter(sqltext,conn);
    da2.Fill(ds,"catalyst");
    ds.Relations.Add("myrelation",ds.Tables["location"].Columns["location_id"],ds.Tables["catalyst"].Columns["location"]);

    DataGrid1.DataSource=dv;
    DataGrid1.DataBind();

    conn.Close();
  }
  catch(OleDbException ex)
  {
    info.Text=ex.Message;
  }
}
</script>
