前台代码部分：

复制代码 代码如下:

<asp:repeater runat="server" id="repeater1" OnItemDataBound="function2">

<itemtemplate>

<asp:repeater runat="server" id="repeater2">

<itemtemplate>

</itemtemplate>

</asp:repeater>

<itemtemplate>

</asp:repeater>

后台代码部分：

复制代码 代码如下:

private void function1()

{

repeater1.datasource = datatable;

repeater1.databind();

}

private void function2(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 rpt = e.item.findcotrol("repeater2") as repeater;//找到里层的repeater对象

datarowview row = (datarowview)e.item.dataitem; //找到分类repeater关联的数据项

int typeid = convert.toint32(row["id"]); //获取填充子类的id
