Error if RadAjaxPanel has serverside code

[test]

I got this runtime error when using RadAjaxPane
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
My code is

<

 

telerik:RadAjaxPanel ID="RadAjaxPanel3" runat="server" LoadingPanelID="LoadingPanel1">

 

 

 

<table width="100%" border="0" cellspacing="0" cellpadding="0">

 

 

<tr>

 

 

<td style="width: 105px"><a href="#" id="idCompliance" runat="server">><asp:ImageButton ID="btnCompliance" runat="server" ImageUrl="~/images/btn_compliance.gif" /></a></td>

 

 

<td style="width: 105px"><a href="#" id="IdCalc" runat="server"> <asp:ImageButton ID="btnCalc" runat="server" ImageUrl="~/images/btn_calculate.gif" /></a></td>

 

<%

If isProclose = True Then%>

 

 

<td style="width: 105px"><a href="#" id="idProcloseDownload" runat="server"><img src="<%=m_strVirtualPath%>images/btn_xml.gif" alt="" width="85" height="34" style="border-style: none" /></a></td>

 

 

<td style="width: 105px"><a href="#" id="idMathCorpInDownload" runat="server"><img src="<%=m_strVirtualPath%>images/btn_in.jpg" alt="" width="85" height="34" style="border-style: none" /></a></td>

 

 

<td style="width: 105px"><a href="#" id="idMathCorpOutDownload" runat="server"><img src="<%=m_strVirtualPath%>images/btn_out.jpg" alt="" width="85" height="34" style="border-style: none" /></a></td>

 

<%

End If%>

 

 

<td align="right"><a href="#" id="IdPrint" runat="server"><asp:ImageButton ID="btnPrint" runat="server" ImageUrl="~/images/btn_print.gif" /></a>&nbsp;

 

 

<a href="#" id="IdCourier" runat="server"><asp:ImageButton ID="btnCourier" runat="server" ImageUrl="~/images/btn_courier.gif" /></a></td>

 

 

</tr>

 

 

</table>

 

 

</telerik:RadAjaxPanel>
I know the server-side code "<%If isProclose = True Then%>" caused the error, If I removed it, it is back to work. But I can't remove it there are two many.

Your help is apprecated.
Thanks
