title: ASP.NET page validation
body: <p>I have a requirement wherein I have a bunch of about 10 aspx pages.The user shall be able to go from one screen to another using navigation.All the range , custom,regex validators need to file so that data enetered is correct.Required fields need not be entered at this stage and the user can skip required fields. On the last page, I need to find out all the fields which are required and if incomplete want to show the user, these fields are required, sort of summary with link to the page where the control was left blank.
  Does any one have any good ideas to achive validation on pages which the user has left and can do validation at the very end before the data is submitted. Any pointers would be greatly appreciated.</p>
