Any solution yet for the above?  

In Jquery UI Dialog, when I included the script and clicked the select button, nothing happened.
If I move the code to main page then it works.

It works for a server that's configured for Kerberos but with on a different server with NTLM it fails with pop up prompt.

Hello Lenny_shp,

There used to be a problem with RadAsyncUpload when it is inside a jQuery dialog but we have fixed it for the latest version, please give it a try.

As for the pop up, the following steps should be undertaken in order to workaround it:

1) Enable anonymous authentication in IIS
2) Allow for anonymous access to the RadAsyncUpload handler:

<location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
        <authorization>
            <allow users="*" />
        </authorization>
    </system.web>
</location>

Does this work for you? If it fails for some reason, please open a support ticket and send us a sample that reproduces the problem. This will allow us to receive a better insight on the problem that you experience.

Best wishes,

Same issue.  However, we are developing to an internal site where anonymous authentication is NOT allowed.

We need a multi-file uploader.

What is a solution for this?

Hi Jay Leffue,

I am happy to announce that we have managed to resolve this issue. The upcoming Q3 release of RadAsyncUpload will be able to work with Windows Authentication while the Anonymous Authentication can be turned of as long as there is Silverlight installed on the client's browser.

Sincerely yours,

Hi Dhandapani,

Please make sure that you are using the correct version of our controls and RadAsyncUpload control is not using Flash module to upload files. To disable Flash module please add the following javascript code before the declaration of the RadAsyncUpload control.

Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; };

Hello Dhandapani,

Could you clarify which module RadAsyncUpload is using after disabling the Flash module? You can see this with right button click on the control or with the following sample code. E.g.
var upload = $find("RadAsyncUpload1");
alert(upload.get_loadedModuleName());
