Combo boxes, list boxes, and other controls

Form with bound, calculated, and unbound controls

Callout 1 These three bound controls show data from the Products table.
Callout 2 This calculated control multiplies the unit price by a discount percentage, without changing the unit price data.
Callout 3 These unbound controls do not have a data source. Their information is stored in the control.

There are three basic types of controls: bound, calculated, and unbound.

Bound controls are in direct connection with a database. They enter data in the database or show data from the database. They can change data, or they can show changes in data as those occur.

Calculated controls perform calculations using database data, but they do not change it.

Unbound controls contain information but are not directly connected to database data.
