ViewState is responsible for maintaining data across the Page Post Back
Does ViewState is responsible for maintaining data across the Page Post Back for Postback controls (like textbox, dropdownlist) and non-postbackcontrols(like label)?
It is false. For NonPostback controls it is true but for postback controls, ASP.NET retrieves their values one by one from the HTTP request and copies them to the control values while creating the HTTP response.

Background of ASP.NET Session State
ASP.NET session state enables you to store and retrieve values for a user as the user navigates ASP.NET pages in a Web application. HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests. ASP.NET session state identifies requests from the same browser during a limited time window as a session, and provides a way to persist variable values for the duration of that session. By default, ASP.NET session state is enabled for all ASP.NET applications.
Alternatives to session state include the following:
*
Application state, which stores variables that can be accessed by all users of an ASP.NET application.
*
Profile properties, which persists user values in a data store without expiring them.
*
ASP.NET caching, which stores values in memory that is available to all ASP.NET applications.
*
View state, which persists values in a page.
*
Cookies.
*
The query string and fields on an HTML form that are available from an HTTP request.
