You can limit the dates and times that can be selected by setting the property and building a custom format string.That means that we can add another partial class with the same name to extend the functionality of the Movie class. Any methods or properties that you add to this class become part of the Movie class generated by the Entity Framework.We'll add our validation logic to the new partial class. When the Entity Framework generates an entity class, the Entity Framework adds partial methods to the class automatically.In situations where this behavior is not desirable (for example, when using a set of data-bound controls to page through a recordset) use the Format event of the Binding class to set the Month Calendar System. The goal of this tutorial is to explain one approach to performing validation in an ASP. You learn how to prevent someone from submitting an HTML form without providing values for required form fields.
