User Input Validation in ASP.NET
Before submitting a web page to server, Input validation on web page is one of the important task. Presently, six different validation server controls are available for ASP.NET:
- RequiredFieldValidator
- CompareValidator
- RangeValidator
- RegularExpressionValidator
- CustomValidator
- ValidationSummary
You can also customize validation for your own needs. Then, if there are any errors in the form data, these validation server controls enable you to customize the display of error information on the browser. The powerful thing about using these validation controls is that they are easy to implement. Modifying them is a piece of cake, so you can easily check for all sorts of parameters on the input generated from your forms.
