Data Controllers / Data FieldsPrint||
Overview

A data field is a binding of a field to a data controller view. Only one binding of a field can exist in each view. Data fields in form views are organized in categories. The data controller will automatically bind primary key fields and alias fields to a data view if the corresponding data fields are not explicitly defined.

If the value of a field is required for a business rule implementation but should not be displayed to the user, then the data field binding must be created and marked as hidden.

If the field has read roles specified and the user is not matched to the roles, then the data field will become invisible. If the field has write roles specified and the user is not matched to the roles, then the data field will be rendered as read-only.

Data fields can be dynamically rearranged with the help of data controller virtualization.
