| Object Model > True DataControl Objects and Collections > PropertyExpression Object, PropertyExpressions Collection |
A True DataControl can have zero or more PropertyExpression objects in its PropertyExpressions collection. Each PropertyExpression object defines a “dynamic property expression” governing a property of a control residing in the same form with the True DataControl. Use the PropertyExpressions property to access the PropertyExpressions collection. Property expressions can manage a property of any control, not necessarily a data-aware control, including the Form itself.
True DataControl automatically maintains the property value equal to the current value of the expression at all times.
