What is a PostBack? What is ViewState? How is it encoded? Is it encrypted? Who uses ViewState? Why..

Answer / sahil dua

PostBack is the name given to the process of submitting an
ASP.NET page to the server for processing . PostBack is
done if certain credentials of the page are to be checked
against a database (such as verification of username and
password). This is something that a client machine is not
able to accomplish and thus these details have to
be ‘posted back’ to the server.

Viewstate is a collection of name/value pairs, where
control's and page itself store information that is
persistent among web requests.
