How to Avoid Uploading Entire Page on PostBack

I have an ASP.NET search page with a couple text fields and a gridview. It does a pretty common task: the users key in some search criteria, then clicks "GO". The gridview gets returned with whatever the user searched for.

OBSERVATION: if the user chooses to search again by entering new criteria and clicking "GO", the entire grid's contents are being uploaded back as part of the postback.

Not a big problem if the grid only contains a few rows. But if it contains many rows, and the user is on a slow connection, this upload time is causing impatient users to think they've timed out.

QUESTION: What can I do to somehow avoid the unnecessary upload of the GridView's data in this case?

Thanks...

You could use Update panel and partial post back or better ajax to get data only without the markup.

Easy points. I don't have time for this right now and EE is bugging me.
