window.onbeforeunload and postback

[Guest]

I have a function that checks whether the user is trying to navigate away
from the page before saving all their data. I achieve this using the
window.onbeforeunload javascript event. It fires when somone clicks on a
link or button but not when someone changes the selected index of a
dropdownlist or radio button.

I tried registering the following script:
RegisterOnSubmitStatement("submit", "confirmClose;") but it does not fire
when a dropdownlist or radio button list postsback. Any ideas on how to do
this?

Thanks

I just read the onbeforeunload reference at:
http://www.msdn.microsoft.com/libra...hor/dhtml/reference/events/onbeforeunload.asp
and it states that the event can be invoked using the form submit method. I
checked the '__doPostBack' script and it contains the line
'theform.submit()'.

So I guess it should work...but it doesn't. Any ideas?
