Here we will learn the HTML helpers in asp.net mvc, why we need html helpers in asp.net mvc, and how to use html helpers in asp.net mvc application with an example, and the difference between asp.net webform controls and asp.net mvc controls rendering with example.
Let's understand the HTML helpers in asp.net mvc. We will study how to create it.
One of the basic things of any web application is to render HTML as output. In .NET, we have ASP.NET Webforms and ASP.NET MVC framework both will render HTML very well, but they do this differently.
If you have come from an ASP.NET web forms development background, you will think ASP.NET Webforms is better than ASP.NET MVC because you need to write the bulk of HTML that will get rendered in the browser, and writing the whole HTML will make developers a bit crazy, for that ASP.NET MVC came up with HTML Helpers which will help you render HTML in the browser.
The HTML helpers and server controls are the same, and both are used to render html on the browser, but if we use HTML helpers, we don't need ViewState to maintain its state, but server controls will use ViewState to maintain state and data.
The following are the list of HTML helper methods available in asp.net mvc.
Let’s take the example of both asp.net webform controls and asp.net mvc controls.
In asp.net web forms, the hyperlink button control code will be as shown below.
<asp:HyperLink ID="HyperLink1" runat="server">Login</asp:HyperLink>
For the above asp.net webforms hyperlink button, how will the browser render? that would be like as shown below.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<form id="Form2" action="login.aspx" method="post">
<a id="A1" href="Login.aspx">Login</a>
In asp.net mvc link button of HTML helper will be like as shown below
For the above asp.net mvc link button, how will the browser render? that would be like as shown below.
<meta name="viewport" content="width=device-width"/>

If we use html helper method in asp.net mvc that will help developers to write html automatically.
