ASP.NET 2.0 gave developers a server-based styling technology called Themes. From the web.config file a single line can dictate how an entire web site will look. The theme of this site at this writing is called Joshua.
<system.web> <pages theme="Joshua"/> </system.web>
Microsoft tells us that is we want to turn off theming for a given page and not the entire site, we can set the EnableTheming property to false. But this doesn’t work. The web.config setting will override the Page directive.
<%@ Page Language="C#" EnableTheming="false" %>
To get around this bug for a single page, specify a Theme with no value in the Page directive.
<%@ Page Language="C#" Theme="" %>
