In this article I will explain with an example, how to pass (send) data from Controller to View using ViewBag in ASP.Net MVC Razor.
This article will illustrate how to create a ViewBag object, store some data and then access the ViewBag object inside the View using Razor syntax in ASP.Net MVC Razor.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 

What is ViewBag

1. ViewBag is a Wrapper built around ViewData.
2. ViewBag is a dynamic property and it makes use of the C# 4.0 dynamic features.
3. While retrieving, there is no need for Type Casting data.
4. ViewBag is used for passing value from Controller to View.
5. ViewBag is available only for Current Request. It will be destroyed on redirection.
 
 

Example

Controller

The Controller consists of following Action method.

Action method for handling GET operation

Inside this Action method, a string value is set in the ViewBag object and simply the View is returned.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        ViewBag.Message = "Hello MVC!";
        return View();
    }
}
 
 

View

Inside the View, simply the ViewBag object is used to display the Message.
@{
     Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <div> 
        @ViewBag.Message
    </div>
</body>
</html>
