InForm item controls

In the InForm application, each item contains a single control. If that control is a group control, checkbox group, or radio group, it can contain a number of child controls. The InForm database does not explicitly model the completeness of this hierarchy of controls, although it does come into play when determining the completeness of a form.

This appendix uses the following definitions.

Leaf control—Any control that holds a value and does not have children. Examples include:
- Pulldown controls
- Text boxes
Group control—A control that contains children, but does not have its own value.
- Radio group—A control that has a number of options, exactly one of which must be selected.
- Checkbox group—A control that has a number of options, any number of which may be selected.
A group control, checkbox group, and radio group’s children might be simple controls with no values, leaf controls, or other group controls, checkbox groups, or radio groups. Although a group control is a container and has no value of its own, checkbox groups and radio groups do have values that indicate their selections.
Completeness—Generally, an item is considered to be complete if either of the following are true:
- The item's top-level control is complete.
or
- The item's top-level control is a simple or calculated control.
