Reason for my vote of 3 \n This is a quick and dirty solution. It does work for all but the last line. If the user is allowed to add new lines, then the enter key in a field on the last non-empty line will make datagridview add a new empty line. The up and right keys are sent afterwards and make the second-last row receive input.
