what i need besides big bucks:)

i have two dropdownlist controls #1 says choose city #2 says choose state

you choose city and state and the gridview shows

what i want is choose a state and a dropdownlist will appear and when you choose city the gridview will appear.

what i get now is i can choose the state but when i choose the city all the cities from any state show in the city dropdownlist not just the choose state cities
