I'm using NHibernate in my project. With it i retrieve a List of Products and a Collection with wrapper objects that are based on Projects that fall under a Product (so a 1 to many relation). Basicly i want a Grid that displays a list of Products and when i open one of these Products i want to see a list of those wrapper objects.

As it stands right now the wrapper objects doesn't have a foreign key but i can easely add that. I rather not have a list/collection of those wrapper objects in each product.

I've been looking on the web how to make a Hierarchical UltraWebGrid out of this but all i see are examples that work with datasets. I rather not work with datasets because NHibernate does all the communicating with the database.

I have a hard time figuring out how to make this. Some help getting me on my way will be greatly appreciated.
