ok, the time limits are stored in the db, but asp.net can't control the time...
we need some dynamic element in the client side...
You wouldn't control the time client-side, you would simply provide a counter and a thing that warns them when they are running out of time. You have a timestamp taken when the page loads server-side, and should their submission take place after timestamp + time alotted they get an error page. It's a pretty basic straightforward system. Whatever you do, you should not be trusting the clients, all validation should take place server-side.
