check if combo box has selection vb.net
i have 3 combo boxes on a form in vb.net. the 3rd combo needs the selection from both of the previous. How do i check that both cb1 and 2 have items selected?
there is no order of selection the user can change 1 or 2 in either order as long as i can make cb3 respond
