I am trying to create a room reservation system, however I am having some strains.
here is what I am trying to do:
a customer should be able to view available dates for a particular room.I mean dates on which this room is free, so that he does not book a room that has already been taken on the time period he specifies he will be staying in the hotel.
please can anyone give me some help on this or any hint?

I need the codes in asp c#

Thanks
