Steven,

>I'm new to the MMF. Want the functionality of CBizObjMaintenanceForm but with a treeview control instead of a grid on the first page. I tried to create a form based on CBizObjMaintBaseForm by placing a CTreeViewCtrl on it, but life wasn't good. Any advice? TIA

You're headed in the right direction. CBizObjMaintBaseForm is the correct form to subclass. After subclassing the form, you can start out by dropping an instance of CTreeViewCtrl and an associated business object on page 1 of the form (set the business object as the form's primary business object).

Regards,
