Ribbon Workbench challenged...

I need to resolve the following scenario and I really don't know where to start.

In more than one form, I have a SubGrid of new_staff records.

When placed in the Account form, the SubGrid's ribbon must be disabled and user should not be able to double-click on a SubGrid's row to open the edit form.

Instead, when the SubGrid is placed in any other form, its ribbon should be enabled and user should be able to double-click on a SubGrid's row to open the edit form.

Any idea how I can accomplish that?

Thanks for your help.
