 Validation controls enable us to check and validate user’s input and display the corresponding error message either dynamically, statically, or through a summary report. These controls are first treated as invisible controls and after the user has entered erroneous data, they become visible. Validation controls in asp.net are powerful objects, however developers need to understand first their behaviors and methods thoroughly before they can be appreciated.

I have created a simple asp.net page that demonstrate the following validation controls:

- RequiredFieldValidator

- RegularExpressionValidator

- CompareValidator

- RangeValidator

- CustomValidator

AJAX is a great technology that further enhances the capabilities of ASP.NET. With AJAX, web applications behave like windows applications by eliminating the page reloading problems of webpages. Furthermore, it has a vast variety of controls that extend user interactivity and page validation capabilities of ASP.NET applications.

I have created a simple web application that demonstrates some important capabilities of an AJAX-enabled ASP.NET website. Download my demo application using this link:
