Hi!
I'm would like to have an editable Order. Each Order can have many editable items - OrderItems, and each OrderItem can have subitems - Assembly.
If I create next objects-hierarchy, is this correct approach?

Editable Root (Order)
|
--EditableChildList (OrderItems)
   |
   --EditableChild (OrderItem)
      |
      --EditableChildList (Assembly)
         |
         --EditableChild (AssemblyItem)

Thanks!

I think the the hierachy is okay.

It is possible to have a parent with children and also grand grand children.

What is the best way to reference parents from childs?

Imagine that i need to acces to a order property from orderitem for check a rule

I think form CSLA.NET 2.14 upward there is an IParent interface which enables children to access the parent properties , of course you have to cast appropriately.

Just give a try, myself i have not done so but i think will work out.

Another way out is just using events for example if the id of parent has changed then you may want children to react to the events.
