I have an update panel that has the UpdateMode set to "Conditional".
When I call UpdatePanel1.Update() in the VB code it does not work in
FireFox. It works just fine in Internet Explorer 6.0. Any ideas on
how to fix it so it works in FireFox 2.0.0.14?

Because the updatepanel runs on the client and renders part of the
page without calling the server, I'm assuming that the script manager
that it runs on is implemented as a Microsoft behavior. Firefox,
Netscape, Mozilla, IE4 and earlier do not support Microsoft
behaviors. You can test if this is the problem by trying to run your
stuff on these other browsers. If it is because of behaviors, then
your app won't work on these either.

W3C has another HTML extensibility model equivalent to MS behaviors
called Actions. To get your stuff to work on Netscape based browsers,
you will have to re-implement the script manager and update panel
controls as Actions (or see if somebody else has already done that).

Anyone know anything about implementing the update panel as Actions?

forget about this actions malarky - can you post an example that
demonstrates the issue ?

most likely you have a scripting error on the page that prevents the ajax
call. install firebug in ff and see what your error is.

.Update is a server sde method, so if it is firing with ff, then you have a
serverside error, as this means the ajax library is running.

the update panel supports ff and safari, no additional code is required.

Fixed. Apparently this is a known issue with images in UpdatePanels.
I "change" the imageURL of the imagebutton to something different each
time, by appending "?a=" followed by a number which gets incremented
each time. Now the image updates properly.
