I'm spitting out the page via xml, so I can't add the runat="server" at design time, is there some way I can add it in the OnPreInit method maybe??

Hi,

If you are using Master pages.. then have to make sure that <head runat="server"> is there in the master page.

hello guys.

i believe that the head element must be a server element since it's one of the sections that is sent back from the server to the client during a partial postback (ie, it's contents are parsed and send on every partial postback response).

Hi,

I had the same problem. An .aspx page with a placeholder, loading an ascx control in code behind.

I replace the <head> section in my aspx page with <head id="headSection" runat="server" >, and now it works.

As the ascx control had an updatepanel, i had to do the loadcontrol in the page-init method.

Hope that will solve your pb.

Grz, Kris.

Ok, but i'm not using themes and I still go that message. I don't know if it matters, but my scriptmanager control resides in a content page as opposed to the master page.

But i am not using any themes in my website which is fairly simple ASP.NET 2.0 impelementation. Infact i am using Atlas in .ascx control and .ascx control is loaded first then the page, as a result scripmanager is unable to see the <head runat=server> tag and generates this error.

Any clue?

I got this too (which is easily fixed by making the head runat="server") but is this a requirement on any page using Atlas?

As designed, you need that runat attribute.

When i use <atlas:ScriptManager> tag in .aspx or .ascx pages without <head runat =server> , i get the following error. Is this a bug or as designed?
