Hi!
I am trying to develop an application for a client. He wants to register his clients and products and manage the orders of the clients as well. My problem is the creation of the invoice orders!
I have created 3 tables (clients, products, orders). I have also a form with a DBGrid that will hold all the invoice orders details. I want my user to click on the grid, select a product, quantity and automatically see the subttoal of the order and then move to the second row so as to make another selection and so on...
i do not know how to start and do not have any clue... Based on search I made I must use DB Grid & DB ComboList but I did not find any simple example so as to see what happens before I start... Any links or ideas?
