GridView的主从多级嵌套

RowDataBound与1.x中的ItemDataBound也有一腿!

=========================================

我已经通过FindControl找到这个gridview，可是现在的问题是我要给这个gridview里帮定的数据源是个新的，和外面的gridview数据源不是同一个！下面是我的部分代码： 
< asp:GridView ID = " GridView1 "  runat = " server "  AutoGenerateColumns = " False "  OnRowDataBound = " GridView1_RowDataBound " >  
    < Columns >  
      < asp:BoundField DataField = " type "  HeaderText = " type "   />  
        < asp:TemplateField >  
          < ItemTemplate >  
            < asp:GridView ID = " GridView2 "  runat = " server "  AutoGenerateColumns = " False "  EnableViewState = " False " >  
              < Columns >  
                 < asp:BoundField DataField = " pub_id "  HeaderText = " pub_id "   />  
              </ Columns >  
            </ asp:GridView >  
          </ ItemTemplate >  
        </ asp:TemplateField >  
     </ Columns >  
</ asp:GridView >  


      protected   void  GridView1_RowDataBound( object  sender, GridViewRowEventArgs e) 
     { 
          if  (e.Row.RowType  ==  DataControlRowType.DataRow) 
         { 
             e.Row.Cells[ 1 ].FindControl( " GridView2 " ); 
         } 
     } 

可是在FindControl("GridView2")后只有一个DataBind()方法，并没有DataSource这个属性，要怎样才能给里面的那个GridView2指定一个新的数据源呢？


--------------------------------------------------------

GridView GRTemp=(GridView)e.Row.Cells[1].FindControl("GridView2");
GRTemp.DataSource=你的source；
GRTemp.DataBind();

Repeater嵌套:

=======================================================================================

// 在绑定分类品名时,绑定分类下的产品 
private   void  rptCategories_ItemDataBound( object  sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) 
{ 
    BLL.Products products  = new  BLL.Products(); 
     if  (e.Item.ItemType  ==  ListItemType.Item  ||     e.Item.ItemType  ==  ListItemType.AlternatingItem)  
    { 
        Repeater rptProduct  =  (Repeater) e.Item.FindControl( " rptProduct " ); 
         // 找到分类Repeater关联的数据项 
        DataRowView rowv  =  (DataRowView)e.Item.DataItem; 
         // 提取分类ID 
         int  CategorieId  =  Convert.ToInt32(rowv[ " ID " ]); 
         // 根据分类ID查询该分类下的产品，并绑定产品Repeater 
        rptProduct.DataSource  =  products.GetProductsByCategorieId(CategorieId); 
        rptProduct.DataBind(); 
    } 
} 

=========================================================================================

gridView嵌套:

========================================================================================

  protected   void  gvUserList_RowDataBound( object  sender, GridViewRowEventArgs e)
    {
         if  (e.Row.RowType  ==  DataControlRowType.DataRow)

        {
            DataRowView rowv  =  (DataRowView)e.Row.DataItem;
          
            Label lblCareer  =  (Label)e.Row.FindControl( " lblCareer " );
             string  tmp_myCareer  =  rowv[ " mycareer " ].ToString().Trim();
           

          }
     }
