05-Feb-2020Usually in asp.net MVC, we use Html helpers in a view so to render Html content. The asp.net MVC Html helper is a method that helps us to return Html content as a string.
The web application’s basic thing is to render HTML as output. In the .NET platform, we have ASP.NET Webforms and ASP.NET MVC frameworks to render HTML but they do rendering things in different ways.
In the ASP.NET Webforms, we only drag and drop the control on Form and in code behind .cs file, we will bind data to server controls to display HTML content on the page and in ASP.NET MVC we have only HTML Controls to display content in the page.
If we came from ASP.NET Webforms development background we will think ASP.NET Webforms are better when compared with ASP.NET MVC because here we need to write bulk of HTML that will get render in browser and writing the whole HTML will make developers bit crazy so to solve this problem ASP.NET MVC came up with HTML Helpers that will help us to render HTML in browser and the HTML helpers and server controls both are used to render HTML on browser.
In the asp.net MVC applications if we use HTML helper it won't maintain any ViewState and loading time of website which will reduce and page performance will increase drastically. In asp.net MVC razor view we have a different type of HTML helpers available these are
1) Basic HTML helpers
2) Strongly type HTML helpers
