View - Rules Tab
You can access rules by clicking on the Rules tab in the Properties menu of a control, or click Add Rules on the Rules tab toolbar. The Rules Designer displayed when you do this allows you to configure rules, conditions, and actions of a rule that gives your view some interactivity and logic, such as calling a SmartObject method when a button is clicked. You can configure rules for controls, views, and forms to create simple to complex business logic. See the rules topic for detailed information about configuring rules, including information about rule inheritance.
