Always tag properly, and formulate your question nicely with a proper title. This would let your question reach to proper audience must faster.

You are missing reference to System.Web.Extension.dll in your project.

Make sure your website is AJAX enabled, and AJAX extension dll's are referenced properly. If needed, just Google for AJAX CTP and how to have AJAX site up.
