Hiii,
I am developing web application in .NET.
If some how while filling any page the users session expires i am redirecting him to the login page..but that means he has to fill the complete details again for that particular page.
I want when he clicks on Submit button of that page I will check the particular condition in header and if Session expires-a login page pop up should come where i will again ask for user name and password. After verifying that his particular data will be saved.
Please help me how to do it.

Retain the State of Page if Session Expires

Hi!
Thanks for asking! I'm a member of the ASP.NET team, and was just popping over here to see what was going on. The best place to ask ASP.NET questions is over on the ASP.NET forums at
http://www.asp.net/welcome.aspx tabindex=1&tabid=39The short answer to your question is that you'll likely have to do some custom authentication stuff to store the data in the form before verifying or forcing the login to happen again. Check out the ASP.NET forums for suggestions on this.
HTH,
