Heres the problem i have a datagridview that i pre populate depending on a month that they select but i only populate one column and leave the other 2 blank for them to input numeric data. How should i do a check to make sure all cells have been filled in? Whats the best way to do this? I don't want to do an update or insert form values unless they have filled in the 2nd and 3rd column values.
e.g if they select february i populate a column called day from 1 to 28 and leave the other cell values blank
MonthDay NumberPeople NumberClass
How can i force the input ? when the add button is clicked on the windows form?
Appreciate any help
