HTML.RenderAction in ASP.NET MVC: A Tutorial with Code Examples. ASP.NET MVC is a popular framework for developing web applications. One of its key features is the ability to render partial views within the main view. HTML.RenderAction is a method used in ASP.NET MVC to render a partial view as an action result. This method provides a way to reuse and modularize code in a clean and maintainable manner.

In this tutorial, we'll show you how to use HTML.RenderAction with a code example. Here are the steps:

Create a new ASP.NET MVC project using Visual Studio.
Create a new controller called "HomeController" with the following code:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
    
    public ActionResult RenderPartialView()
    {
        return PartialView();
    }
}

Create a new partial view called "RenderPartialView.cshtml" in the Views/Home folder with the following code:

This is a partial view
This view is being rendered using HTML.RenderAction.

In the Views/Home/Index.cshtml file, add the following code to render the partial view using HTML.RenderAction:

Main View
@Html.RenderAction("RenderPartialView", "Home")
    

In conclusion, HTML.RenderAction is a useful method in ASP.NET MVC for rendering partial views as action results. It allows for clean code reuse and modularization in a web application. By following the steps in this tutorial, you should now have a basic understanding of how to use HTML.RenderAction in your own ASP.NET MVC projects.
