RegularExpressionValidator not firing in panel

[Craig Wallace]

Hi,

I have a series of RegularExpressionValidators in an asp:panel which is marked Visible="false".  This panel is later made visible and the page is updated with a RadAjaxManagerProxy control.  When I later submit the form, using a button in the same panel, one of the RegularExpressionValidators does not fire.  It does not even fire on the server-side.  What can I do to resolve this?

Thanks.

This was just me being an idiot and missing runat="server" on the control.
