10.7. Summary

In this chapter, you learned how to use validation techniques, from the very simple to the fairly advanced. You learned to use a variety of validators and even created a robust validation scheme in ActionScript. You learned how to restrict input fields, limiting the type of characters that are allowed, and you learned to use a few new controls, such as RadioButton and DateField.

This chapter also covered looping, which is a more advanced scripting technique than we have used in previous exercises. You learned how to format data by creating an application using some formatter classes. You also learned to perform calculations on dates and times. All of this, used in conjunction with the form layout, gives you the know-how to create rich, user-friendly forms for Flex applications.
