Lesson 12: Create Custom Validations by Inheriting from the ValidationAttribute Class
In this lesson you learn about the ValidationAttribute class and how you use to build your own custom attribute classes. You create three classes to validate dates. One class validates a date is less than a maximum value specified in the attribute. One class validates a date is greater than a minimum value specified in the attribute. The last class passes in two integer values to specify how many years prior and in the future the date value entered must be within.
