Why should you care?

Product pages, forms, and admin tables all use ViewBag or build on it.

See it live — copy this example

Create an MVC project (dotnet new mvc), add the code, and run dotnet run.

// ViewBag — ShopNest.Mvc example
public class HomeController : Controller
{
    public IActionResult Index() => View();
}

Run Example »

Edit the code and click Run — like W3Schools Try it Yourself.

What happened?

• Study the example line by line.
• Each part connects to ViewBag.
• Edit one line, save, and run dotnet run to see what changes.

Try it yourself

1. Locate the .cshtml file that uses ViewBag.
2. Change one line and refresh the browser.
3. Match the example code to your project file.
4. Change text or labels in the example and run again — watch the browser update.
5. Break the code on purpose (remove a semicolon), read the error message, then fix it.

Remember

You learned what ViewBag is and when to use it. Practice by changing the example yourself. Explain it in your own words before moving on.
