Themes work at the theme level; you can switch themes by assigning the theme property of the page in the PreInit event...

Alternatively, you could create multiple themes for a GridView control, and give it a SkinID within the ASP.NET theme. Then, you can change the SkinID for the GridView to the theme you want to apply. This would be for skins only, CSS doesn't work this way.

HTH.
