Readonly

Learn about Readonly attribute.

If checked, the field is read-only and cannot be changed by the user.

For fields defined as read-only in the access rights definition (Fields column > Deny Update) you do not need to set the Readonly field attribute.

Fields with Deny New in the access rights definition are displayed as read-only in Edit/New mode. In Edit/Update mode users may enter a value but the field is reset to empty on save.
