Problem with viewstate/session?

Hi Guys,

I have a website and getting a 'Page Not found' error, when I click on 'Modify' button on a .asp page. I am not able to replicate this when I debug the application. Its pulling the Modify screen with all controls. In application using viewstate to store the control information.

Can anybody suggest me why its working fine through the code but not through the website? same code is deployed on webserver.

Thanks for your help.

What page is not being found?

Please post some code too..

My application have a webpage which displays all transactions.When I click on 'Modify' button against a transaction it supposed to bring up another page with some controls to enter the data and modify. Its working fine for all transactions when I debug the application but through the website its throwing error (default error page) for some transactions.

Since its working fine while debugging the application not able to find/isolate the problem and what exactly missing or causing this on website (that too only some transactions).

Pls. help me in this.
Thanks for all your time and help.

Can you get a specific error message from the default error page?

No. Just 'Page Not Found' error.

Wondering why its working for some transactions, why not for other? and working fine with code execution. Is there any way to check what's going on at web server side when I click on 'Modify' button on website?

Thanks for your help.
