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?

Server Error in '/AtlasWebSite' Application.

As designed, you need that runat attribute.

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

Hi,

no it isn't. If you're using Themes in ASP.NET 2.0 it's required to have that attribute.

Grz, Kris.

Read my blog. ASP.NET AJAX Control toolkit Modalpopupextender control, some tricks..

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?

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.

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.

Gilles

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).
