Not answered RadAjaxLoadingPanel

Posted on Feb 8, 2012 (permalink)

I am having a strange problem that I can reproduce. I have a Windows 2008 R2 server with the default Document setup to bring up the default.aspx page. I am running the latest build of the Telerik controls.

On my default.aspx page all I have on the page is the RadScriptManager, RadAjaxLoadingPanel, RadAjaxPanel and a asp button inside the RadAjaxPanel. The RadAjaxPanel is set with the LoadingPanelID of the RadAjaxLoadingPanel.

On the button click event I have System.Threading.Thread.Sleep(5000) this is to just have the loading panel display the loading image just to make a simple test.

This all works just if I call the http://sitename/default.aspx page, but if I just call the http://sitename and have the server load the default document “default.aspx “ the loading panel will not function and display the image. The problem only occurs on Windows server 2008 R2. I do not have the problem on Windows server 2008 or Windows 7.

I have contacted Telerik support and they have basically told me this is my problem, even though I have recreated this on 3 different Windows 2008 R2 servers and 2 different projects. So I guess I am just wondering if any of you have seen this problem or you could test this and see if this is really just me.

Thanks for any help
Mark

Hi Mark,

The behavior you observe is due to a known issue. Check the solution at the bottom of this article:
