Enable or disable viewstate in

View State is the method to preserve the Value of the Page and Controls between round trips. It is a Page-Level State Management technique. View State is turned on by default and normally serializes the data in every control on the page regardless of whether it is actually used  during a post-back.  

These are the main features of view state:
  1. Retains the value of the Control after post-back without using a session.
  2. Stores the value of Pages and Control Properties defined in the page.
  3. Creates a custom View State Provider that lets you store View State Information in a SQL Server Database or in another data store

Maintaining the ViewState is the default setting for ASP.NET Web Forms. 

If you want to NOT maintain the ViewState, include the directive <%@ Page EnableViewState="false" %> at the top of an .aspx page or add the attribute EnableViewState="false" to any control.
