Complete Guide to HTML Helpers in ASP.NET MVC

Introduction

While developing web applications in ASP.NET MVC, we often create forms with inputs like:

• Textbox

• Dropdown

• Checkbox

• Buttons

We can write these using plain HTML, but ASP.NET MVC provides a better way called HTML Helpers.

HTML Helpers help us generate HTML elements in a clean, easy, and strongly typed way.

In this article, you will learn:

• What HTML Helpers are

• Why we use them

• All important helpers with examples

• HTML vs HTML Helpers
