RadAsyncUpload broken in IIS7 integrated mode or controlRenderingCompatibilityVersion = "4.0"

[Brent]

I have been having problems with a RadAsyncUpload control that was previously working in ASP.NET 3.5 after I converted imy app to ASP.NET 4.0.  I confirmed that all my web.config settings were correct.  When I selected a valid file, I would get the exclamation point as if I had chosen a file that failed validation.  I did not see any javascript errors in Firebug, and I had no error messages coming out of it.  I knew that the file I selected wasn't the problem, and no changes had happened in the code since the upgrade to .NET 4.0.  Changing IIS 7 to "classic mode" made it go away, but that was not an option for me.  Plus I knew that integrated mode shouldn't be the issue since I had all the appropriate web.config settings.  After a bit of trial and error, I found that if I set "controlRenderingCompatibilityVersion" in the web.config to 3.5, the error went away.

I wanted to post this to share it with the rest of the community, and alert Telerik to a potential bug.

I stand corrected.  It turns out that the root of my problem was "runtimeVersionv2.0" being in my httpHandlers declarations of my web.config.  This allowed it to work correctly in IIS 7 ASP.NET 4.0 classic mode, but not in IIS 7 ASP.NET 4.0 integrated mode.

Thanks to the Telerik gang for helping me out!

The RadAsyncUpload is working fine with the environment Windows server 2003 with IIS 6.0. But now we have upgraded our environment with Windows server 2008 and IIS 7.0.


In this new environment, I checked the both classic and integrated mode of applicaiton pools and tried the way (http://www.telerik.com/community/forums/preview-thread/aspnet/upload/iis-7-and-the-progress-area.aspx#tForumTop) you suggested to do to make it works as perfect. But though we are getting the issue on uploading files.
 

I am just selecting a file. Instead of GREEN mark for the successful selection, It shows RED mark with the script error as attached. I have attached the screenshot. Please check it and help us to solve this issue asap.
