.NET form not loading inside thickbox window?

Question

I'm working with a website built in .net,

I have a very simple popup box (thickbox) which works fine up until my developer puts the .net contact form within the popup.

The problem is that the form no longer shows up inside the thickbox, has anybody experience this before?

Its not like its even calling data from elsewhere, all the content is on the page in a hidden div that when requested the javascript shows the popup.

My popup window looks like the following...

<div id="hidForm">
    <asp:Panel ID="PL_Im_Popup" runat="server" >
    .net stuff here doesnt load!
    </asp:Panel>
    The stuff outside of the .net panel works fine 
</div>

---

My entire code is...

<div id="hidForm">
<asp:Panel ID="PL_Im_Popup" runat="server" >
