Hello,



I added a child object to the primary object on the SF maintenance form. But it looks like the child object doesn't participates in form's edit. When user clicks "Edit" button in the maintenance form's toolstrip, Child object's text boxes don't become editable. I checked and set all the relevant BO properties (e.g. IncludeInFormEdit).

What else do I need to do?



Thank you.

No.  If you are using the MaintenanceFormToolstrip, they will not automatically change states.  If you look at the StrataFlix sample, you can see that in this case they do automatically show up (Save and Undo) but the MaintenanceFormToolstrip is not used.  So in this case, you will have to manualy set the states by handling the IsDirtyChanged event of the BO if you are going to take this route.
