Cross Page Posting

• 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 post back) 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.
