I have my DataGridView set up and can change the numbers, etc. but when I exit the changes weren't saved. Now I have created a Tool strip with 4 buttons. A Save, Save As a coppy of the dataase, Undo and Forward button. Should I add any
other buttons? How can I make a messagebox to pop up vhen I want to exit and if I click Yes in the messagebox it would save the changes and if I click no it would just exit?
