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 rpt.datasource = datatable; rpt.databind(); } |
