The controls will disappear if both these are true:
a) There are records to display, and
b) No new records can be added.
You can easily determine whether there are records in the form's Record
Source. In addition you may need to consider any Filter applied to the form.
No new records can be added if the form's AllowAdditions property is set to
No, or if the form is based on a query where records can't be added. To test
that, try opening the query and adding records directly there.
