The problem is sporadic, so I'll try to explain.. hopefully it's something small that I'm missing.
Currently, we are using ASP.NET AJAX Q1 2008 (515.20). I've got a main page with RadAjaxManager and several UserControls with RadAjaxManager proxies. Each UserControl has its own loading panel defined and, on request, the loading panels show up correctly. However, they won't go away after the response ends.
I verified that the events were happening with OnRequestStart and OnResponseEnd events by sending a javascript alert. No javascript errors or exceptions were thrown. Any ideas?

I am experiencing the same exact thing. For me, the page was working perfectly under RadControls classic. After upgrading/converting to RadControls for Ajax, I am getting this behavior.
For me, I have a similar structure:
- Main page loads user control (A) dynamically. It contains
the RadAjaxManager.
- user control (A) contains tabstrip within which (multipage) has
a user control (B). Tabstrip is set to autopost back and
multipage to render only current page.
- user control (B) has several fieldset. Checkbox in fieldset's
legend enables/disables the other controls in that fieldset,
which themselves are contained in a panel.
- user control (B) on pageload looks at parent page and finds
the RadAjaxManager, then via code calls AddAjaxSetting
and adds the appropriate controls.
If I modify the code in user control (B) to not assign a loading panel in the AddAjaxSetting, then it works fine.

I am experiencing this issue all of a sudden with an older app that uses 2008 Q1 (415) controls. I am not able to upgrade this app to a later version because of changes made in the Ajax Framework subsequent to this release. Can you suggest anything I can do as a patch or hack to avoid this issue?

Hello Albert,
I am afraid there is no custom patch for this discrepancy for this rather outdated version of RadControls for ASP.NET AJAX. You may consider migrating to the newer version of the product which includes the fix.

Hi,
It seems to be the same issue than our post : http://www.telerik.com/community/forums/aspnet-ajax/ajax/infinite-radajaxloadingpanel-issue.aspx ?
Since the issue exiss with latest online samples it seems to be a different one, thanks to Telerik to confirm this ?

I'm having same issue with loading panel not disappearing. My controls are set up very much like what Clayton described above back in 2008. I'm using version 2011.3.1115.35. Can you help fix it for good or point me to the fix? Thanks

Hi Owen,
The issue you are facing is not a common issue, though the most possible reason for it are wrong ajax settings or improper loading of the dynamic user controls. That is why you be able to help you fix it, we will need a runnable version of the which we can debug. Can you open a formal support ticket and send as the page and the user controls there? Or paste the code which we can use to replicate it here.

I am experiencing a similar problem in that the RadAjaxLoadingPanel stays up indefinitely after the response returns.
I am using the 2012.1.215.35 version of the controls and have an interesting context in which the code is running.
I have a ModalPopUpExtender open and inside I have a RadGrid. Within the grid I am tying the buttons inside my templates to the RadAjaxManager programmatically.
For whatever reason, the panels are appearing just fine, but sometimes (intermittently) they won't disappear.
Any help is much appreciated.

Hello Brian,
Is it possible that some javascript error occurs in these cases? This can be preventing the page execution to finish successfully and thus the code for hiding the loading panel is not called.

I have not seen any JavaScript errors display on the page when the loading image hangs. The page appears to have completed the response without error, just the loading image intermittently doesn't go away.

Hello Brian,
Do you have a live Url which we can use to see the issue? We might need steps to replicate.
The other way to help you troubleshoot the issue, is to send us a sample showing it in a Support ticket.

Hi,
I'm having a similar issue but it only seems to be happening when I deploy to the server. When I run it locally in visual studio it works fine. When it does break there isn't any JavaScript errors showing up it just doesn't disappear. The Telerik assemblies I'm using on the deployed website are the same as the local ones I'm using so I don't think it's a version issue. My only thought is it's some kind of IIS peculiarity. The site is running on IIS v6.1 on .Net 4.0. Anyone have any thoughts?
Version of "Telerik.Web.UI.dll" is 2011.2.915.35

Hello Richard,
Can you let us know what is the JavaScript error?
Also, if the web site is running under .NET 4.0, you need to use the .NET 4.0 dlls, e.g. Telerik.Web.UI.dll version should be 2011.2.915.40. You can find the .NET 4.0 dlls in the installation folder of RadControls for ASP.NET AJAX on your machine.

Hi Iana,
Sorry, I said I wasn't getting any kind of javascript error it just fails to go away when the async postback completes. I also tried updating the dll to the Version 4.0 one which had no effect then I updated my project to the 2012 Q1 dlls as well which also didn't help at all unfortunately. I'm really stumped by this as it works perfectly running locally so it's more difficult to debug when it only happens when it's deployed to the remote server.
The only thing I can think of trying is the web.config because that is also different to the local one but it seems to need to be for a host of reasons. I'll try to make it more like the local one see if that makes a difference. Is there anything in the web.config you can think of that would cause this kind of thing to happen? :

Hello Richard,
The web.config looks fine to me. However as this is .NET 3.5. web.config, you definitely need the .NET 3.5 dlls of the Telerik.Web.UI, not the 4.0 ones.
Can you give me a live Url where I can observe the issue? If you cannot share the link, etc.in the public forums, you can open a formal support ticket for that purpose.

Thus we will be able to concentrate ion your specific case and advise you further.

I will bump this topic as the problem is still persisting in Product Version 2013.1.220.40
Randomly, the RadAjaxLoadingPanel1 stays on, since the page is covered user is locked out of the page. This is very serious, as it forcing the user to go in and out of the system, which is time consuming.
There is no issue with the setup because it works, most of the time, but sometimes at random it just does not work.
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Silk"
AnimationDuration="500" BackgroundPosition="Top">

Hello Martin,
The most common source of the presented behavior is a error that appears on the page, prevents the OnResponseEnd client event to fire and therefore the RadAjaxLoadingPanel could does not have an event to hide on.
I would suggest you to inspect the server response in the browser console and verify if any errors appear.

I was able to reproduce the error, this is how I did it. I constantly pressed the refresh button, very fast, and the animation would not want to go away. So the spinning wheel was not going away. I've resolved this by removing altogether the property AnimationDuration="500".

Hello Martin,
The issue you are facing is caused by the fast subsequent ajax request executed. Note that by design, the ASP.NET AJAX Framework cancels the ongoing AJAX request if you try to initiate another one prior to receiving the response from the first one.In this case the ResponseEnd client event will not fire for the terminated request and this is leading to the presented behavior.
To change this behavior, you can set the RequestQueueSize property to a value greater than zero, which enables the queueing mechanism of RadAjax, and will allow you to complete the ongoing request and then initiate the pending requests in the control queue.
