How do you create a view in ASPNET MVC

In ASP.NET MVC, a View is responsible for rendering the user interface (UI) and displaying data to the user. Views are typically written using Razor syntax, which allows you to embed C# code within HTML. Below is a step-by-step guide on how to create a view in ASP.NET MVC.

Step 1: Create a Controller

Before creating a view, you need a controller to handle the request and pass data to the view. Here's an example of a simple controller:


public class HomeController : Controller
{
    public ActionResult Index()
    {
        // Pass data to the view
        ViewBag.Message = "Welcome to ASP.NET MVC!";
        return View();
    }
}

In this example, the Index action method returns a view and passes a message using ViewBag.

Step 2: Add a View

To create a view for the Index action, follow these steps:

Right-click on the Views folder in your project.
Select Add > New Folder and name it Home (to match the controller name).
Right-click on the Home folder, select Add > View.
Name the view Index.cshtml (to match the action name).

Step 3: Write the View Code

Once the view is created, you can write the HTML and Razor code to display the data. Here's an example of the Index.cshtml view:


@{
    ViewBag.Title = "Home Page";
}

<h2>@ViewBag.Message</h2>
<p>This is the home page of the ASP.NET MVC application.</p>

In this example:

@ViewBag.Title sets the title of the page.
@ViewBag.Message displays the message passed from the controller.

Step 4: Run the Application

After creating the controller and view, run the application. Navigate to the Home/Index URL, and you should see the message "Welcome to ASP.NET MVC!" displayed on the page.

Key Points to Remember

Views are stored in the Views folder, organized by controller name.
Razor syntax (@) is used to embed C# code within HTML.
Use ViewBag or a strongly-typed model to pass data from the controller to the view.

By following these steps, you can easily create and manage views in your ASP.NET MVC application.
