Making a field read-only in a grid edit report

So i thought I was being clever but kind of utilizing the 2nd option you provided. But what I did was create a copy of the original field in the form and set that one to be read only in the form properties and only be shown when viewing a record. Then set up rules to mark it checked or unchecked based on the original field being checked or unchecked when adding or editing a record, which that all worked perfectly. However the intent was to be able to use that field that was marked as read-only in the report that would be used for grid-editing instead of the originally field, but when I tested it out, that read-only field was no longer read-only once grid edit mode was entered. 

But you are saying that if I just create a separate form and make that original field as read-only, that will do the trick instead?
