How do I include thead in a runat=“server” table element?

Question

I\'m upgrading a big web site project from Visual Studio 2010 to 2012. Throughout my project, I have table elements with the runat=\"server\" attribute

Answer 1

I don't have VS 2012; right now but you should try following things

1. Can you verify changing DOCTYPE. (to transitional, frame-set, 1.1 or html 5 etc)
2. Put the whole table inside asp:placeholder
