Img Mapth Paths

I have an image of a theater, which has been broken down by the number of seats in the theater in the shape of the theater.
What i would like to do, is allow the end user to select the seat they would like to sit at - Even the seats in a corner and the recorded in a database i.e. Seat selected Row A Seat 45. Can this be achieved by ASP .Net or is this a bad design option? If yes how could i start? keeping in mind every seat click should not overlap the seat next to it and this image would be part of an existing ASP .Net site.

Thanks
