Hello Pronic,

Please make sure that you haven't set MinDisplayTime property to la large value. It specifies the minimum time in milliseconds that the Loading Panel will last. The control will not be hidden before this period has passed even if the request returns.

Thanks,
Princy.

no it's just like this...

<telerik:RadAjaxLoadingPanel ID="SantiyeListesiRadAjaxLoadingPanel" Skin="Web20M" EnableEmbeddedSkins="false"

runat="server">

</telerik:RadAjaxLoadingPanel>

I have been having an issue with a similar thing (RadAjaxLoadingPanel stays on forever), but ONLY in DEBUG mode. If I run the application normally (non-debug) the loading panels work correctly (i.e. they don't stay ON).

Anybody have any idea why this would happen in debug and not go away?

This is becoming a pretty serious issue, because if I click around enough, my entire page is filled with loading panels and I can't actually get to much of my page.

I have a pretty complicated app with a series of user controls (within other user controls) and a number of ajaxRequests going on, but can't pinpoint why this happens to me... and only in debug. But, like I said... It makes it so I can't actually debug anything because they pop up and stay on everywhere.

All my panels are defined like this:

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" Runat="server"

Skin="Default" InitialDelayTime="1000" MinDisplayTime="1000">

</telerik:RadAjaxLoadingPanel>

Hello Shawn,

Could you please try using some browser's dev tool and inspect the Ajax response you are receiving. Most probably the problem originates of a javascript error which terminates the response and therefore the LoadingPanel stacks. Please do so and verify if any errors appear in debug mode.

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.
