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