Run code before leaving

[aTekTipsUser]

In asp.net, I am trying to run code before leaving the page. I've tried using window.onbeforeunload to ask the user if they want to save. If they say yes, I mark a hidden checkbox, and re-submit the form. Then, on the page_load event, I check to see if the hidden checkbox is checked and if it is I save to the database. This worked fine running on my system, but when I posted it live on the web, it did not work, it did not update the database. Any ideas on how to save to a database before leaving the page? I want this code to run whenever the users click the x to close the window or the back button. Thanks in advance.

There is no reliable way to determine when a user is leaving the page. They could close the browser, use the Task Manager to kill the browser process, or just shut off their PC or modem.

You'll need to implement a Save button.

This will work on 95% off the browser out there now.

It has some draw backs. It is not silent.
