Controller
The Controller consists of the following Action method.
Action method for handling GET operation
Inside this Action method, a string value is set into a TempData object i.e. Name and simply the View is returned.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        TempData["Name"] = "Mudassar Khan";
        return View();
    }
}
 
 
View
The View consists of a TextBox created using Html.TextBox helper function. The TempData object is passed as the second parameter i.e. the value of the TextBox.
@{
    Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width"/>
    <title>Index</title>
</head>
<body>
    @Html.TextBox("Name", TempData["Name"])
</body>
</html>
