saving data when browser is closed

[Nikhil Patel]

Hi all,
I am writing an ASP.Net app. I first read application data from Sql Server
and store it in a DataSet. When the user is no longer running the
application, I would like to save the contents of the DataSet. I know I can
probably use Page_Unload event. But will the Page_Unload event fire if the
user closes the browser window?

Thanks.

Hi Nikhil,

The onunload event is a client-side thing that you might be able to get
working in IE.

Here's an example

You may be able to take advantage of the client side OnClose event.

You can use the Session_End event in your HttpApplication class (e.g.
global.asax). This will fire once the sssion's timeout kicks in or it is
terminated by a user action that class HttpSession.Abandon(). This works
only for InProc sessions, though.

As far as session_end event goes.... I've never had it
reliably fire. Or in the event it DOES fire... it doesnt
always appear to have access to the same data.

I had something that when their session expired it'd just
clear out application data that was registered with their
user (old code of somone elses design)

Sometimes the reference to application was avaliable,
sometimes it wasnt.
