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
I don't have VS 2012; right now but you should try following things
For partial solution you can move that <th>
front-end code to the back-end code.
That should take care of the compilation problem.
Don't know what to do about <tbody>
tags though.
If you view HTML of your page as it stands now, I doubt that they render anyway.
Here is why.
Simple solution remove tags tbody and thead, for me worked.
Yes Its a bug in Visual Studio 2012,Applying the patch from below mentioned link has worked for me: http://www.microsoft.com/en-us/download/details.aspx?id=36359
Removing the tag won't solve it out for a current/migrating running project. In that way we have to change each and every aspx page.
Fix for this issue is available now. http://support.microsoft.com/kb/2750149 for windows 8 and http://support.microsoft.com/kb/2750147 for Windows 7 platform.
Microsoft has confirmed this is a bug. They will create a hot fix for it, and include the fix in the next service pack. It doesn't sound like this is a high priority, so it will probably take a while for the hot fix.
2012-10-01 Update: Microsoft support contacted me and said this will be fixed in an upcoming hot fix "soon".
2012-11-28 Update: Visual Studio 2012 Update 1 does not fix the problem.
