How do I link a datagrid back to the mainview??

Question: 

If I have a main view SERVICE, with a datagrid showing CONTACT_SERVICE records linked to this, how do I make the Add/Edit actions pass the correct ID to the Edit form? (The edit form is bound to CONTACT_SERVICE)

Answer:

Make sure all the following conditions are met.

1. You have Data Form (Contact) for main view
2. You have Data Form (Contact_Service) for edit view
3. On main view form you have DataGrid with following parameters:

   • BindID = ContactID
   • When you edit SQL property in Query Builder on “Grid Details” tab there Table field is set to Contact_Service and below field is set to Contact_Service.ContactID
   • When you edit SQL property in Query Builder on “Layout” tab there is Contact_ServiceID field
   • Keyfield = Contact_ServiceID
