I created a wizard and in the step1 the user should select a customer. Then in the second step I wanna show the invoices in a grid for the customer selected. The user could mark some invoices and when the user select one (or some), i wanna show user in a textbox the sum of the Amount of the invoices selected.
I just have the step1.
How I do the second step that depends of the AccountNum selected by the user?
Please help me.
