CHAPTER 20 Enhancing Forms

Users Guide 571

You modify properties based on conditions you specify by entering an

expression in the Properties view for the control. In this example, the

expression for the salary column's color property is:

if( employee_salary > 30000, 255, 0 )

For more information

For information on modifying properties based on conditions you specify, see

Chapter 10, “Highlighting Information in Reports and Forms.” The technique

works the same way in forms and reports.

Displaying and validating data in a form

Some of the most important ways to enhance forms are to create:

• Display formats to specify how values are formatted

• Edit styles to specify styles in which values are presented and entered

• Validation rules to ensure that values entered in forms are valid

Display formats, edit styles, and validation rules are usually created in the

Database painter (if you have access to the database). In the Form painter, the

database definitions apply to the data unless you override them with new

definitions. The new definitions you create in the Form painter do not affect the

definitions in the database; the definitions are used only in the form.

For more information, see Chapter 8, “Displaying and Validating Data.”
