[thelist] How to empty a gridview in 2.0

[Anthony Baratta]

Can it be reliably said, that when a user enters the page with no post or "additional" querystrings they are looking to start "fresh"? If so, re-init all your controls and start everything over.

Therefore, anytime a non-Post method activates your page - start everything over.
