I'm working on a POS form and I have the following question.
In my example it would be like modifying the quantity of the same product on a single line without having to repeat the product every time it is added to the cart.
gridItens.DefaultCellStyle.Font = new Font ("Tahoma", 12); gridItens.AutoGenerateColumns = false;
txtEAN.Focus();
ITENS = new BindingList<ItemVendaView>();
gridItens.DataSource = ITENS;
AtualizaTotais();
