Your code shows that you are trying to do it on Windows Form using Data Grid. It would be a lot easier for anybody to see and run the code if you share the solution as a zip file. Also, where did you stuck ? what're you trying to do but couldn't? And what you want help with ? Is it for everything that is listed on assignment or is there anything specific you want help with ( I saw that you have done something, but without running it I really can't help you)

I will be online for few hours, so if you share the zip file I might able to help you.

And one personal experience - I always waited until the last minute for everything and thus always have miserable consequences. Don't do that my friend.. Just my one cent advice. :)
