By default, ASP.NET submits a form to the same page. In cross-page posting, the form is submitted to a different page. This is done by setting the �PostBackUrl� property of the button(that causes postback) to the desired page. In the code-behind of the page to which the form has been posted, use the �FindControl� method of the �PreviousPage� property to reference the data of the control in the first page.
