What validation techniques are used in MVC?

Question

Accepted Answer

Validation technique in MVC is used to ensure that the data entered by the user is valid and meets the specified criteria.

Validation can be performed at different levels in MVC, such as client-side validation using JavaScript or server-side validation using data annotations or custom validation logic.
Client-side validation provides immediate feedback to the user without making a round trip to the server, while server-side validation ensures data integrity and security.
Data annotations in MVC allow developers to define validation rules directly on the model properties, such as required fields, string length, range, regular expressions, etc.
Custom validation logic can be implemented by creating custom validation attributes or by using validation frameworks like FluentValidation.
Validation messages can be displayed to the user using validation summary or validation message helpers in the view.
Example: [Required] attribute in MVC ensures that a field is not empty and displays an error message if it is.
Example: Regular expression validation can be used to validate email addresses, phone numbers, etc.
