A field represents a column of a data row. There are physical and virtual fields. Virtual fields are not derived from a physical column of a data table – their values are computed at runtime. Bindings of fields to views are called data fields.
In the Project Explorer, fields are contained under the Fields node of a controller. If an asterisk (*) is present after the name of the field, the field is required. The field type and length are displayed in parentheses. Some fields fields may display “read-only” label.
Creating a Field
A field can be created by using the New Field context menu option on the Fields node.
Fields can be moved using drag and drop operations.
Dropping a field node onto another field node will place the field after the target field.
Dropping a field node on the right side of another field node will place it after the target field.
Dropping a field node on the left side of another field node will place it before the target field.
Fields can be copied to a different controller by dragging onto the controller or Fields node. The original field will not be deleted.
Creating Data Fields
When fields are dropped onto a view or category, they will be instantiated as data fields in the target view. When the field is dropped onto a form view, the data fields will be appended to the last category.
Cloning a Field
A field can be copied by dropping onto the controller or Fields node while holding Ctrl key. The name of the clone will be appended with a number, and the new field will be configured as a calculated field that reflects the physical column in the database. Use context menu option Copy on the field and use Paste on the controller or Fields node to create a clone.
Create Standard Validator and Converter
When an option is selected, the field is configured as calculated, and a business rule will be created.
Deleting a Field
Fields can be deleted using the context menu option Delete. This will also remove all data fields, items, and field outputs.
