viewstate means to store the data when page is postback that
is called viewstate.

Answer / guru gangadhar

Web Page is a Stateless.
So when the page is post backed the data doesn't persist.
In asp.net view state is present by default which is used to
store the data , we can store the data in view state at the
code behind while the page is post backed.

You ve defined one page_load event in aspx page and same page_load event in code behind how will prog run?
