.net - use Repeater Item index in Hidden Field -

how set item index in repeater column hidden fields in asp.net.
wrote following code not show index value in hidden field.

<itemtemplate>     <tr>         <td>             <asp:hiddenfield id="hiddenfield1" runat="server" value='<%# container.itemindex+1 %>' />             <%--<asp:hiddenfield id="hfindex" runat="server" value='<%#container.itemindex+1 %>' />--%>         </td>         <td>             <asp:label id="lblexpenseglcode" runat="server" text='<%# databinder.eval(container.dataitem, "acm_account_code")%>'></asp:label>         </td>         <td>             <asp:label id="lblaccountgldescription" runat="server" text='<%# databinder.eval(container.dataitem, "acm_account_desc")%>'></asp:label>         </td>     </tr> </itemtemplate> 

i can't see wrong itemtemplate, if provide entire repeater code direct copy / paste in case there area other errors.

another approach can take add repeater data item bound event , capture hiddenfield in event. once have hidden input can set it's value.

repeater code:

<asp:repeater id='myrepeater' runat="server" onitemdatabound='myrepeater_onitemdatabound'>       <itemtemplate>         <asp:hiddenfield id='myhidden' runat="server" />       </itemtemplate> </asp:repeater> 

and code behind event:

protected void myrepeater_onitemdatabound(object sender, repeateritemeventargs e)     {         if (e.item.itemtype == listitemtype.item || e.item.itemtype == listitemtype.alternatingitem)         {             var myhidden = (hiddenfield)e.item.findcontrol("myhidden");             myhidden.value = e.item.itemindex.tostring();         }     }
