I believe that this isn't possible. Although UpdatePanel updates only a portion of the page, a full post-back is always happening. This is why an UpdatePanel isn't recommended for Ajax applications. You may consider using an Ajax client library, like jQuery and ajax-enabled WCF services. This will be much more efficient than UpdatePanels.
