Answer / monica jeevan
When a form is submitted in classic ASP, all form values
are cleared. Suppose you have submitted a form with a lot
of information and the server comes back with an error. You
will have to go back to the form and correct the
information. You click the back button, and what
happens.......ALL form values are CLEARED, and you will
have to start all over again! The site did not maintain
your ViewState.
When a form is submitted in ASP .NET, the form reappears in
the browser window together with all form values. How come?
This is because ASP .NET maintains your ViewState. The
ViewState indicates the status of the page when submitted
to the server. The status is defined through a hidden field
placed on each page with a <form runat="server"> control.
Maintaining the ViewState is the default setting for
ASP.NET Web Forms. If you want to NOT maintain the
ViewState, include the directive <%@ Page
EnableViewState="false" %> at the top of an .aspx page or
add the attribute EnableViewState="false" to any control.
