Here we will learn what are the html helpers in asp.net mvc, why we need html helpers in asp.net mvc, how to use html helpers in asp.net mvc application with example and difference between asp.net webform controls and asp.net mvc controls rendering with example.
Let's understand what are the HTML helpers in asp.net mvc and later we will study how to create it.
- We use HTML helpers in a view to render HTML content in asp.net mvc
- An HTML helper is just a method that returns a string.
One of the basic thing 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 thing in different ways.
If you have come from ASP.NET webforms development background then you will think ASP.NET Webforms is better as compare to ASP.NET MVC because here you need to write bulk of HTML that will get render in browser and writing whole html will make developers bit crazy. For that ASP.NET MVC came up with HTML Helpers which will help you to render html in browser.
The HTML helpers and server controls are the same and both are used to render html on 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.
Following are the list of html helper methods available in asp.net mvc
Let’s take example of both asp.net webform controls and asp.net mvc controls
In asp.net webforms hyperlink button control code will be like as shown below
<asp:HyperLink ID="HyperLink1" runat="server">Login</asp:HyperLink>
For above asp.net webforms hyperlink button how browser will 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 above asp.net mvc link button how browser will render? that would be like as shown below
<meta name="viewport" content="width=device-width"/>
<link href="/Content/site.css" rel="stylesheet"/>
<form action="/PersonDetails/index" method="post">
If we use html helper method in asp.net mvc that will help developers to write html automatically.
