html code :

<asp:repeater id="repeater1" runat="server"          onitemdatabound="repeater1_itemdatabound">         <itemtemplate>             <h1>                 repeater 1</h1>             <asp:repeater id="repeater2" runat="server" onitemdatabound="repeater2_itemdatabound">                 <itemtemplate>                     <h1>                         repeater 2                     </h1>                     <asp:repeater id="repeater3" runat="server" onitemdatabound="repeater3_itemdatabound">                         <itemtemplate>                             <h1>                                 repeater 3                             </h1>                             <asp:repeater id="repeater4" runat="server" onitemdatabound="repeater4_itemdatabound">                                 <itemtemplate>                                     <h1>                                         repeater 4                                     </h1>                                 </itemtemplate>                             </asp:repeater>                         </itemtemplate>                     </asp:repeater>                 </itemtemplate>             </asp:repeater>         </itemtemplate>     </asp:repeater>
