Server Side Regular Expression Validation in MVC 4.0

Written By:- Isha Malhotra

Introduction

In my last article series I explained the server side Required, Range and Compare validation. In this article I am going to explain the Regular Expression Validation.

Regular Expression validation is used to validate the pattern like email address, website etc.

For Example

In this example I am applying the regular expression validation on name field. As I applied that it can contain only character

Syntax of Regular Expression

		[RegularExpression("^[a-zA-Z]{1,20}$",ErrorMessage="Kindly Enter only Alphabet")]
      public string stu_name { get; set; }

Now execute this code and you will get following output:- 

		server side validation

		Figure 1

Now enter only character:- 

		Regular Expression validation

		Figure 2

Similarly we can create any pattern and can apply on any control using Regular Expression attribute.
