What are the different validators in ASP.NET?

ASP.NET validation controls validate the user input data to ensure that useless, unauthenticated, or contradictory data don’t get stored.

ASP.Net Validation Control

The validation control is used to implement a page level validation in server controls.

There are 6 types of ASP.Net Validation Control:
- RequiredFieldValidator
- RangeValidator
- RegularExpressionValidator
- CompareValidator
- ValidationSummary
- CustomValidator

  1. RequiredFieldValidator

Indicates the input Control is not empty when the form is submitted.

Syntax

2. RangeValidator

The Rangevalidator control is verifies that the input value falls within a given range of number, date or string.

Syntax

3. RegularExpressionValidator

The RegularExpressionValidator control validates the input text of a control that matches a pattern defined by a RegularExpression.

Syntax

4. CompareValidator

The Comaprevalidator control compares the value of one control to another using a comparison operator.

Syntax

5. CustomValidator

ASP.Net also allows the freedom of writing your own validator. This eases the task of a developer to validate the form at the client side itself. It also allows putting more complex validations in place. Validations that are business or application-specific can be written using custom validators.

Syntax

6. ValidationSummary

The ValidationSummary control doesn’t perform any validation. Instead, it shows a summary of errors raised by each control on the page.
