Why State Management ?

In traditional web programming information associated with the web page and with controls of page will be lost between post-backs.

Ex:-when user enters some text in text box (or) mark a check-box (or) selected an item in combo-box,that information(changes) will be lost in the round trip from client/browser to server.

To overcome this Asp.net Introduced severel methods to store data on the client-browser/server and retrieve from client-browser/server.

• View State
• Control State
• Hidden Fields
• Cookies
• Query Strings
• Application State
• Session State
