State Management in ASP.NET
* A new instance of the Web page class is created each time the page is posted to the server.
* In traditional Web programming, all information that is associated with the page, along with the controls on the page, would be lost with each roundtrip.
* The Microsoft ASP.NET framework includes several options to help you preserve data on both a per-page basis and an application-wide basis. These options can be broadly divided into the following two categories,
* Client-Side State Management Options
* Server-Side State Management Options
Client-Side State Management
* Client-based options involve storing information either in the page or on the client computer.
* Some client-based state management options are,
* Hidden fields
* View state
* Cookies
* Query strings
Server-Side State Management
* There are situations where you need to store the state information on the server side.
* Server-side state management enables you to manage application-related and session-related information on the server.
* ASP.NET provides the following options to manage state at the server side:
* Application state
* Session state
