Set Postback or Session Timeout

[kurt]

Hi All.
I have a page that users enter information in text boxes...and
sometimes it's a lot of information. There are times that these folks
either take their time entering the info or do other things before they
submit the page. Unfortunately, if they do take their time, there are
times where the session times out and they can no longer submit their
information, resulting in an error and pretty peeved users.

What I'm asking for help on is....can, possibly through a timer or
something either reset the session or do a postback? This would be to
cover in case the user would take too much time to submit the
information.....it would happen automatically. I do have a popup box
that warns them they are about to time out, but it might not be seen.

So far, I have tried a timer to redirect the page to itself, try to go
through the page_load and try to set the session.timeout, but none of
it looks to work. I did see some __doPostBack and Page.GetPostBackEvent
articles, but didn't see how to put them to use. They get mentioned,
but I don't see how to make them function on my page. I need some way
to try to keep the session alive and not timeout. Sorry if it's
something that's easy that I don't see. I'm still a bit (ok, well very)
new at this I have searched Google high and low and found nothing that
looks to work.

Thanks for any help you can be!!

You can:
1. Extend the length of the session timeout.
2. Store your information in ViewState instead.

Maybe you can use a (small) iframe that refreshes itself every few minutes,
to keep the session alive but without submitting the entire page
(and losing scroll-position and focus).

Sorry I didn't get back sooner, but I was out for a while. I'm not
sure extending the timeout would work. If I set it to 30 minutes,
they'll probably go 31...and so on. I also wasn't sure that the
viewstate would be usable and last either. But, I did try the iframe
and so far it looks to do exactly as I needed. I also have been trying
it out and I don't look to lose focus from the control I'm currently
using when the iframe refreshes. Thanks for all the input!!
