My new form, has a treelist (already populated with a BO). This treelist has 2 type of nodes (categories and accounts).

When the user click on an account, I want to display a panel with the fields from the Account BO and when he clicks on a category, I hide the account panel and display the category panel with the categories BO fields.

I have also an MaintenanceFormToolStrip.

What's the best approach to manager this two panels with his BO?

I think that changing the primarybussinesobject from the from every time the users clicks on an treelist item and retrieving the selected item in the business object can be the solution, but I'm not sure?

Thanks,

Alex B.
