  • Razor files have a .cshtmlextension


View template file

HTML Response to user

Change the Index method

  • Current Index method returns a string.

  • Change it to return a View object.

Controller method or

Action Method

public ActionResult Index()


return View();


Add a View Template

  • Right click inside the Index method

  • Click Add View

Click here

The Add View Dialog Box

Leave defaults alone


New Folder/File Created …

New Folder

New File

The contents of the Index.cshtml file

  • Add the following HTML under the <h2> tag.

  • <p>Hello from our View Template!</p>

  • The complete MvcMovie\Views\HelloWorld\Index.cshtml file is shown below.

  • @{

  • ViewBag.Title = "Index";

  • }

  • <h2>Index</h2>

  • <p>Hello from our View Template!</p>

Click on _Layout.cshtml


  • Placeholder

  • All view-specific pages show up here

  • View pages are “wrapped” in layout page

  • When you select the About link

    • The Views\Home\About.cshtmlview is rendered inside the RenderBody method.

Change the site title

  • Change “your logo here” to “MVC Movie”:

<div class="float-left">

<p class="site-title">@Html.ActionLink("MVC Movie", "Index", "Home")</p>


Replace the title element:

<title>@ViewBag.Title - Movie App</title>

Run the app; also check the “About” page

Note the changed title

Changes in the Layout template to the title will be reflected in all the web pages

Change the title of the Index View

Open MvcMovie\Views\HelloWorld\Index.cshtml

ViewBag is an object in the view template


ViewBag.Title = "Movie List";


<h2>My Movie List</h2>

<p>Hello from our View Template!</p>

Passing data from the Controller to the View

  • Controller classes

    • Invoked for an incoming URL request

    • Where you write code to:

      • Handle incoming browser requests

      • Retrieve data from a database

      • Decide what type of response to send back to the browser

    • Call a View class to generate and format an HTML response back to the browser

Best Practices

  • Controllers provide data to views.

  • A view template should never perform business logic or interact with a database directly.

  • View should work only with data provided by controller (Separation of Concerns)




Pass data from a Controller to a View via the ViewBag …

URL containing Message, NumTimes

Parameters: Message, NumTimes

HelloWorldController, Welcome Action

ViewBag Object

Welcome View



Modify the Welcome method in the HelloWorldController

using System.Web;

using System.Web.Mvc;

namespace MvcMovie.Controllers


public class HelloWorldController : Controller


public ActionResult Index()


return View();


public ActionResult Welcome(string name, intnumTimes = 1)


ViewBag.Message = "Hello " + name;

ViewBag.NumTimes = numTimes;

return View();




Automatic Binding to query string

ViewBag can contain anything (dynamic)

Create a Welcomeview template

  • F6- compile the project

  • Inside the Welcome method:

    • Right-Click

    • Select Add View

    • Click Add on the Add View dialog box

    • The Welcome.cshtml will be added to the project

Add logic to display data in a loop

  • Modify Welcome.cshtml …


ViewBag.Title = "Welcome";




@for (inti=0; i < ViewBag.NumTimes; i++) {




  • Run the app:

    • http://localhost:xx/HelloWorld/Welcome?name=Scott&numtimes=4

We’ve built a Controller and a View …We’ll build a Model next …
