ASP.NET AJAX Q3 2011 Upgrade Problem

[John McNamara]

HI,

I have been asked to upgrade a web application to RadControls ASP.NET AJAX Q3 2011 from Telerik ASP.NET Q3 2007  ( I know !!!!) . I am using a master page, dev language is c# and am targetting .net 4 framework.

I have ran the upgrade wizard and emoved all reference to previous Telerik versions,

Problem is I get the following error when launching master page "Using themed css files requires a header control on the page." ( I'm not using a themed css as far as I can see )....
When I add runat="server" to the master page I get the following error when I launch a page containing RadGrid "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."

so I am in a vicious circle !!!

I searched all forum but the answers always relate to .NET 2.0...

Any suggestions on this?

Thanks so much in advance,
John

I got that message - and fixed it by moving javascript with <%= %> constructs (jquery finds) to RadCodeBlock(s)
