Very good so far!

I haven't looked at the resulting where clause, but I hope you know to parameterize the user values and not concatenate them into a query string. That leads to SQL Injection and no amount of escaping the user-entered values is foolproof.

In the demo, I think there should be and/or drop down after each condition. I'd like to see the filter represented in a grid with a vertical scrollbar as well as the results grid with a vertical scrollbar.
