***NEWBIE USER*** Update SQL table via DataGrid - Windows Form Project using C#

Question

I have been tasked with a Project.  I am so green to Visual Studio it's not even funny but I am quick to learn.  I have already figured out how to create a dataGridView and connect to a SQL database, in order to populate to two columns I need to display.

After these columns have populated I need help to update one of the columns.  Coulmn 1 is a vehicle.  Coumn 2 is the vehicle price.  The point of the project is to be able to update column 2 and then press an update button and have it write back to the SQL database.  A cancel button to not update anything.  An undo option.  and finally one of thos big warnings that says you made changes are you sure you woant to proceed.  Then another one saying like hey this will change stuff are you really really really sure.  of course in a much more professional manner =).

Please help, and keep in mind I am GREEN (also read as NEWBIE)

Thanks in advance!
