Hello,

I'm new to CSLA and trying to build my first simple project using CSLA.
So I have a class Product which inherits from BusinessBase. And another class ProductList which inherits from BusinessListBase.
The ProductList is bind to a DataGridView in Windows form, and I want to insert/update/delete products in the grid, but I can not decide how to implement my Product as a root object or as a child of ProductList.
Do I have two root object or one of them is child?
Which is the correct way ot solve this?

Thank you.

Product should be a child of Product List.

I.e. ProductList is BLB/root (of ProductList, Product), Product is a BB/child (of Product) .

Thank you for your answer, but can you explain why.
Is it always like that when you have an object and a list of that object?

thank you

EDIT: I think I found the answer:  Defining parent and child objects
