The short answer is, you can’t - all \<% … %\> code is run, then the  
page is  
displayed.

The long answer is, you could, but there’s probably a better solution.  
The  
way you could do this is to add an event to the document’s onload event  
[How to call scripts - Unobtrusive Javascript](http://onlinetools.org/articles/unobtrusivejavascript/chapter4.html) that  
does an ajax call to the controller that renders the partial.
