Hi All,
            I am working on a AJAX Enabled asp.net web application. Which was previously developed in VS 2005.
Now this application is converted into VS 2008 with Framework 3.5

Now the problem occurs is that,
      Some pages in application working fine with update panels. And some are not working properly.
Those pages are not working with update panel, also don't get the CSS files as Stylesheets.

The AsyncPostBack Trigger Not Fired, with Update Panel's UpdateMode = "Conditional" and RenderMode="Inline". But PostBack Trigger works.

In Web.Config file-
<xhtmlConformance mode="Transitional" />

Any help will be appriciated.
Thanks.

Install Firebug in FF and see what error you get. I would also suggest to create a brand new asp.net ajax project in VS2008 and compare the web.configs.
