Can you render cahnges in the curent and send a Response?

I am generating Word docs from a gridview.  The Word doc gets sent to the client using a Resposne object.  However, I would also like to highlight the row in question and update a file generation log display (another gridview).
 
All the data fucntions on the server side fire fine, but any visual updates to the current page never hit the client.  The Response object seems to take over the entire response.
 
Is there any way to accomplish both: execute the Response and update the current page?
