i'm using the Northwind database and I want to create a C# .Net Framework windows form to generate an order input.
I already linked the tables in my dataset and the binding source and used the binding navigator to be able to view each one of them
The thing is i'm unable to find a way to add the order details to an uncreated order because it throws an exception of inserting null values to the DB. (I thought that using autoincrement will solve it, but it won't)
do you guys have any idea?
