Create Hidden field using HtmlHelper:

Learn how to generate hidden field using HtmlHelper in razor view in this section.

HtmlHelper class includes two extension methods to generate a hidden field (<input type="hidden">) element in a razor view: Hidden() and HiddenFor().

We will use the following Student model with Hidden() and HiddenFor() method.

Example: Student Model

public class Student
    public int StudentId { get; set; }
    public string StudentName { get; set; }
    public int Age { get; set; }
    public bool isNewlyEnrolled { get; set; }
    public string Password { get; set; }


The Html.Hidden() method generates a input hidden field element with specified name, value and html attributes.

Hidden() method signature:

MvcHtmlString Html.Hidden(string name, object value, object htmlAttributes)

Hidden() method has many overloads. Please visit MSDN to know all the overloads of Hidden() method.

The following example creates a hidden field for StudentId property of Student model. It binds StudentId with the hidden field, so that it can assign value of StudentId to the hidden field and visa-versa.

Example: Html.Hidden() in Razor View

@model Student


Html Result:

<input id="StudentId" 
            value="1" />


HiddenFor helper method is a strongly typed extension method. It generates a hidden input element for the model property specified using a lambda expression. HiddenFor method binds a specified model object property to <input type="hidden">. So it automatically sets a value of the model property to hidden field and visa-versa.

HiddenFor() method signature:

MvcHtmlString Html.HiddenFor(Expression<Func<dynamic,TProperty>> expression)

Visit MSDN to know all the overloads of HiddenFor() method.

Example: HiddenFor() in Razor View

@model Student

@Html.HiddenFor(m => m.StudentId)

Html Result:

<input data-val="true" 
            data-val-number="The field StudentId must be a number." 
            data-val-required="The StudentId field is required." 
            value="1" />

In the above example, the first parameter in HiddenFor() method is a lambda expression that specifies the model property to be bind with the hidden field. We have specified StudentId property in the above example. So, it generates input text element with id & name set to property name. The value attribute will be set to the value of a StudentId property which is 1 in the above example.

Please notice that it has created data- attribute of html5 that is used for the validation in ASP.Net MVC.
