We are using data binding in our application, and are having trouble
finding out how to bind a hierarchy of lists of business objects.

What we have is this hierarchy:

List<Orders>
|
(Order)
|- List<Groups>
|
(Group)
|- List<Members>

We want to create a form where each of these lists is displayed in a
grid, and data is updated depending on what the user selects. The grids
cannot be nested. Can this be done?

We found the solution: Use the master/detail pattern with nested
BindingSources for the grid hierarchy, and everything works.
