Ajax Loading panel no longer displays

[Keith]

The ajax loading panel in our project fails to display. It was working, and although we have not modified the settings, it is now no longer working.

Relevant code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
    DefaultLoadingPanelID="RadAjaxLoadingPanel1" >
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="btnShowAll">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="Content" LoadingPanelID="RadAjaxLoadingPanel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Black" MinDisplayTime="1000">
</telerik:RadAjaxLoadingPanel>

The panel is rendered correctly in the html code however, the panel does not display on postback.

This was working last week. It stopped working after updating the Telerik controls on Monday.

Hello Keith,

Thank you for contacting us.

Since the problem in your project was not present before upgrading the Telerik controls and that there is no obvious reason for the provided code to behave as you have described I would ask you to assure that all necessary steps described in the help topic bellow were taken into account:

• Upgrading RadControls
   

I am attaching a simple project with your scenario, working as expected on my side. Check it out and let me know what is the difference in your case.

Kind Regards,

I should have mentioned that this is a project in development. After having troubles with other ajax requests, we updated the controls to determine if that would fix our issues. It did fix the issue we were having, but now, despite having rebuilt the entire project, including supporting dlls, the loading panel doesn't display.

I'll review the project you posted and see if I can make a determination on what the issue may be.

Hi Keith,

I hope that the project I attached in my last post and the documentation for upgrading RadControls helps you with your issue.

If you experience any other difficulties, please don`t hesitate to get back to us.

Kind Regards,
