大家好，又见面了，我是你们的朋友全栈君。

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 >

                     & 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 >
