Hi, basically when a form is submitted with the use of asp.net in any type of web project, all form values are cleared. So, consider if user submit his form which contains more information and he gets an error while submitting it. Then if he click on back button then he would not able to get any type of information. So, it is needed that to store that information which is maintained by the viewstate.

Hello, I am also the beginner in ASP.net, but I have come to know that the ViewState is a mechanism to maintain state in ASP.net pages. As you know the HTTP is a stateless protocol. This state can be saved on either server or on client using sessions, cookies, hidden variables, URL, etc. ViewState is a hidden field maintained by ASP.Net to contain page data. That's what I know. I am not have more about this.
