In asp.net pages, during postback, ViewState makes the data persistent. What makes the data persistent in ASP.net MVC?

- 1By the way, I think you have misconception about the viewstate. ..viewstate doesn't persist data in the application, it just maintain the page status between requestsstackunderflow– stackunderflow2014-05-13 05:47:33 +00:00Commented May 13, 2014 at 5:47

In Asp.Net we have Runat="Server" to make controls like Textbox,Checkbox... into asp.net controls which they run at server and they can maintain viewstate because of they are server controls.
Http is Stateless:
Http is stateless i.e; for it forgets the controls value (like Textbox,Checkbox) for every request that means it doesnt maintain state.To make stateful we use state management techniques like ViewState,Querystring,Sessions,Cookies in Asp.Net.
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 .

The MVC tries to apply the concept of Http protocol statelessness!! So there should be no viewstate equivalent to that of the asp web forms.
However in single page application, aka SPA : you use java script library on client to manage the page and contact the server using Ajax! So it gives the impression. That the viewstate is maintained
