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
- 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
