Working with Data Fields

Data fields are bindings of fields to views.

Form views organize data fields in categories. Data fields are placed directly under the root of other types of views.

Data fields selected under c1 category of editForm1 view in the Categories controller in the Project Explorer for web applications.

Creating a Data Field

Data fields are created by using the New Data Field context menu option. For grid views, the option is available on the view node.

Arranging Data Fields

Data fields can be rearranged using drag and drop operations. Dropping a data field on another data field will place it after the target.

Dropping a data field onto a different view or category will copy the data field. If the data field is already present in the view, it will be moved to the bottom of the list.

Dropping data field Picture onto view grid1.      The existing Picture data field has been moved to last in the list.

Creating Master-Detail Relationships

Dragging data fields can quickly create master-detail relationships between data views. Simply drag the foreign key field from the child view onto the master view. The relationship will be automatically configured.

Overview of Data Fields

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.

Data Field Properties:

Property Description
Aggregate Function Specifies a function that will be performed on the rows in grid view. The value will be displayed at the bottom of the grid.
Alias Specifies an alias for the field. The alias will be used to display values. The header text of the alias will be used.
Auto Complete Minimum Prefix Length Specifies the number of letters required for auto-complete to be displayed. If less than 1, auto-complete will be disabled.
