Hi Guy's
I have a problem in populating database data in dropdowm box.

I had 4 drop down box and 4 table, based on first drop down selection second dropdown value should get populate,based on second 3'rd drop down should get populate and based on 3'rd dropdown selection 4'th drop down should get populate.

No refresh of screen.I know it can be done using javascript but i am not getting any clear idea how to achieve it.I am using asp on server side and javascript on client side.

If any one can give sample eg it will be very help full thanks in advance.
