Is ViewState relevant in ASP.NET MVC?

Question

I am learning ASP.NET MVC and many concepts of "ASP.NET" like authentication, authorization, session state still apply to it.

But from whatever little I have understood, I don't see that ViewState is still relevant in an ASP.NET application. But it is there (property of System.Web.Mvc.ViewPage)! Is it there only for compatibility reasons or it still have some purpose/use?

Answer 1

Its present because ViewPage inherits from Page. However Page itself had no use for ViewState its used by WebControls. It is possible to include original WebControls in a View but doing so would be completely missing the point of separating control from view.

Answer 2

Yes, that is correct. ViewState is not relevant. More on differencies between Page Model and MVC here:

Answer 3

Personally I think its obsolete. The only time I've seen ViewState in an ASP.Net MVC app is when someone 'accidentally' added a ASP.Net control to a page.
