State Management is a process of maintaining the state of the control or variable after page postback from server or between pages. In Asp.Net we are having many ways to maintain the state management. Basically it is dividied into server side and client side state management. Depends on the resource that we have to plan. They are as follows....
1. Session state
2. Hidden Variables
