DataGrid 嵌套DataList

//DataGrid 嵌套DataList

 //第一层DataGrid
  private void LoadData(DataGrid p_DataGrid)
  {
   SystemTypeF sysTyF = new SystemTypeF();
   DataTable dt  = sysTyF.GetParentCodeListFree();
   p_DataGrid.DataSource= dt.DefaultView;
   p_DataGrid.DataBind();  
  }

 //调用DataGrid 的ItemDataBound方法,具体实现如下：
  
  private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
  {
   string strLoop = e.Item.Cells[1].Text;
   if(strLoop.ToLower() != "typecode")
   {
    string strTypeCode = strLoop;
    DataList  dsFind = e.Item.FindControl("DataList1") as DataList;

    SystemTypeF sysTyF = new SystemTypeF();
    DataTable dtLs = sysTyF.ChildTypeList(strLoop);
    if(dtLs.Rows.Count > 0)
    {
     dsFind.DataSource = dtLs.DefaultView;
     dsFind.DataBind();
    }
   }

   
  }
