Although you can add a control to a form and then bind the control to a field, it is usually more effective to use the Field Chooser. The Field Chooser lets you add a control and bind it to a field in a single step. Also, in many cases, the built-in control provided by the Field Chooser has special features and capabilities that cannot be duplicated by binding a field to a standard control.
Outlook displays the Field Chooser whenever you open a form in design mode.
