UpdateProgress Control and Delays in IE

I have three coordinated UpdatePanels on a page. I set up a single
UpdateProgress control on the page to cover all three update events and show
a nice animated gif.

In Firefox, this works with no problems -- the gif animation pops up, the
update completes in less than two seconds, the gif disappears.

In IE 7, when you click on an item that should trigger an update, it take
about seven seconds for the UpdateProgress control to show the gif animation
(which shows up frozen or jerky), and about another five seconds for the
update to complete.

During this process in IE, CPU usage (on a dual core) pops to and stays at
50%. With Firefox CPU usage jumps to about 13%, drops to near zero, then
pops back to 13% when the results come back.

I tried getting rid of the gif animation and replaced it with a simple text
message. No change in behavior.

When I comment out the UpdateProgress control, IE 7 performs comparable to
Firefox -- no perceptible delay, update completes in under two seconds, and
CPU usage pattern is similar.


Below is the UpdateProgress control code. Can you please tell me why this
was causing such delays in IE 7?

<asp:UpdateProgress ID="ctlUpdateProgress" DynamicLayout="true"
runat="server">
<ProgressTemplate>
<div class="LoaderContainer">
<div class="Loader">
<img src ="/_images/Common/loader-anime.gif"
alt="Updating..." />
</div>
</div>
</ProgressTemplate>
</asp:UpdateProgress>


Thanks,
BJ
 
Good suggestion, but I tried setting DisplayAfter to "0" and "1." It did not
fix the problem.

For the delay try using the parameters DisplayAfter="0" in the
UpdateProgress control.

Oops. Before you ask:

I am using Visual Studio 2008, .NET 3.5 with all patches applied

Hi,

I cannot reproduce this problem on my side. My IE is 7.0.5730.11. Could
you test following page? Do you get the same behavior?

http://www.asp.net/AJAX/Documentation/Live/Samples/System.Web.UI.UpdateProgr
ess1/cs/Default.aspx

Do you have some IE add-ons enabled? If so try to disable all of them to
see if there're any differences. If it's possible, could you test it on
another machine? Will you see the same result?

If it still doesn't work please send me a demo project that can reproduce
this problem and the details about your environment, such as operating
system and IE 7 version. My email is (e-mail address removed).
