Greetings!
I have a little question/problem
I’m trying to make a “sales invoice” API and I don’t know if is possible to make it using a “grid”
Ex: The page loads and the grid shows 1 row and that row will have 4 columns to “ID, Name, Quantity and Price” where ID and Name, allows to you find the correct product and then fill the next info automatic on quantity and price, and once you fill everything it creates another row to do the same again if you want, and later submit those values like a invoice.
Do guys understand this? and if you do… it is possible? because I don’t know how to do this 
I already know how to use a combo box and load things from sql and using json… but using this inside a grid, I don’t know if is possible.
