for cascading of dropdowns , we use the same approach as suggested by Satish.
For the first dropdown (Country dropdown in your case) take Data page as source ( or can be anything as source) then for the second dropdown (State dropdown) take Data page as source which takes 'country' as parameter. if you have already list of states on the Data page they you can use Keyed Page Access option of Data Pages.
Hope I helped you, Please let me know if you need any more details on this
