Repeater嵌套绑定Repeater

Repeater嵌套Repeater的结构：

 cs代码： 

 

Code
 private   void  RpTypeBind()
    {
        // GetQuestionTypeAndCount() 返回一个datatable
         this .rptypelist.DataSource  =  LiftQuestionCtr.GetQuestionTypeAndCount();                   
         this .rptypelist.DataBind();
    }

 protected   void  rptypelist_ItemDataBound( object  sender, RepeaterItemEventArgs e)
    {
        // 判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，
        // HeaderTemplate，，ItemTemplate，SeparatorTemplate）
        if  (e.Item.ItemType  ==  ListItemType.Item  ||  e.Item.ItemType  ==  ListItemType.AlternatingItem)
            {
                Repeater rep  =  e.Item.FindControl( " rpquestionlist " )  as  Repeater; // 找到里层的repeater对象
                DataRowView rowv  =  (DataRowView)e.Item.DataItem; // 找到分类Repeater关联的数据项 
                 int  typeid  =  Convert.ToInt32(rowv[ " qtid " ]);  // 获取填充子类的id 
                rep.DataSource  =  LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid,  2 );
                rep.DataBind();
            }
    }

 

aspx:

table border = " 0 "  cellpadding = " 0 "  cellspacing = " 0 "  style = " margin-bottom: 5px "  width = " 100% " >
     < asp:Repeater runat = " server "  ID = " rptypelist "  OnItemDataBound = " rptypelist_ItemDataBound " >
         < ItemTemplate >
             < tr >
                 < td  class = " fb " >
                     & nbsp; & nbsp; < a href = " Lists.aspx?Qtid=<%#Eval( " qtid " ) %> " ><% #Eval( " qtypename " )  %></ a >   < span id = " askCount_15 "
                         class = " date2 " > [ <% #Eval( " typecount " ) %> ] </ span >
                 </ td >
             </ tr >
             < tr >
                 < td >
                     < div id = " askTop2_15 "   class = " ask_list " >
                         < asp:Repeater runat = " server "  ID = " rpquestionlist " >
                             < ItemTemplate >
                                 < a href = " Question.aspx?qid=<%#Eval( " liftquestionid " )%> " >
                                     <% #Eval( " questiontitle " ) %></ a >< br  />
                             </ ItemTemplate >
                         </ asp:Repeater >
                     </ div >
                 </ td >
             </ tr >
         </ ItemTemplate >
     </ asp:Repeater >
</ table >

 

 

此方法应该适合于repeater嵌套，datalist嵌套。

（datalist嵌套前不久试过，也可以）
