The controller gets the first hit and loads the model. Most of the time we
would like to pass the model to the view for display purpose.
As an ASP.NET developer your choice would be to use session variables, view
state or some other ASP.NET session management object.
The problem with using ASP.NET session or view state object is the scope.
ASP.NET session objects have session scope and view state has page scope. For
MVC we would like to see scope limited to controller and the view. In other
words we would like to maintain data when the hit comes to controller and
reaches the view and after that the scope of the data should expire.
That’s where the new session management technique has been introduced in ASP.NET
MVC framework i.e. ViewData.
set the viewdata variable as shown in the below code snippet and kick of the
view.
important point to note is the view does not have a behind code. So to display
the view we need to use the <%: tag in the aspx page as shown in the below code
snippet.

Step1:- Create project and set view data
So the first step is to create a project and a controller. In the controllerset the viewdata variable as shown in the below code snippet and kick of the
view.
public class DisplayTimeController : Controller
{
//
// GET: /DisplayTime/
public ActionResult Index()
{
ViewData["CurrentTime"] = DateTime.Now.ToString();
return View();
}
}
Step 2:- Display view data in the view.
The next thing is to display data in the view by using the percentage tag. Oneimportant point to note is the view does not have a behind code. So to display
the view we need to use the <%: tag in the aspx page as shown in the below code
snippet.
<body> <div> <%: ViewData["CurrentTime"] %> </div> </body>
