There is a problem when trying to add a new customer. If you do everything by the book the example works perfectly but if you make a small change then you cant add a customer.
Specifically on the form there are 4 combo boxes. In the book we bind 2 of them in code and the other 2 with the UI.
Well if you bind them all with the UI or if you dont bind selecteditem but insted you bind selectedvalue on all 4 combo boxes then you cant add a new customer.
This is very strange and I cant figure out why this is happening. I've been stragling yesterday all day to find why this is happening but I cant figure it out. Maybe it is a problem with bindingsource. Any ideas?
