Validating Form Data

  • Adam Freeman


Most web applications use HTML forms to gather some kind of data from the user. This can range from simple data such as a name and password to complex data that is critical to business processes.

The process of checking the inputs we receive is called validation. This chapter describes the set of Web Forms controls that support validation.
