  • View State is for *non-MVC* ASP.NET "WebForms". View State compromises state stored across post-backs via a HIDDEN field. It is *not* comparable to the View Bag in MVC which is "new each request". See http://stackoverflow.com/questions/23623229/what-is-the-equivalent-of-viewstate-in-asp-net-mvc for MVC alternatives for persisting state. Google - really the resources available that are located by such - will answer such broad non-focused questions; as such this is too broad. – user2864740 Aug 09 '15 at 18:37
  • Did you google it before you asked the question here? There's many examples and explanations out there already – brroshan Aug 09 '15 at 18:40

Coming to your Question

In MVC we dont have Viewstate.In order to maintain the values refer below link

Maintaining viewstate in Asp.net mvc?

ASP.NET MVC doesn't work with ViewState and Postback?

we use ViewBag,ViewData,TempData for the flow of values from controller to view or controller to controller .

ViewState is an old classic ASP.NET WebForms concept when controls and ASPX pages save their state between HTTP requests using a hidden field.

ViewBag is a completely different concept in ASP.NET MVC applications. It's just a simple container that you can use to pass some data from Controller to a View. This state doesn't live between HTTP requests.
