State management

In general, any (typical) web application is stateless. It means that when an event occurs (any event like button click, page load) the web page communicates with the web server using HTTP or HTTPS protocol and gets the response. After getting the response web page destroys and recreates. 

Along with the page, all controls in the page recreates. Between this process, the data exists in the controls will get lost. So, to retain the values of the controls we use state management techniques in ASP.Net.

We have different techniques in ASP.Net to handle state management.
