The RadUpload control constructs the path to the UploadServiceUrl based on the URI of the Silverlight XAP package: System.Windows.Application.Current.Host.Source. Then it strips down this path like this:
Uri source = System.Windows.Application.Current.Host.Source;
serverPath = source.AbsoluteUri.Remove(source.AbsoluteUri.Length - source.AbsolutePath.Length - source.Query.Length);
and the serverPath is combined with the value of the UploadServiceUrl property in order to construct the full path to the UploadHandler. Then the RadUpload logic makes a query to that handler based on the constructed path. We don't have a control over the query results as they strongly depend on the server settings.
This is why we believe that the issue might be caused by settings in your server environment. Sometimes even if the domain name component isn't case sensitive, the path name can be. Can you check if both http://www2.inovisiondb.com/Proto1/RUFileHandler.ashx
paths allow you to access the handler. The result of a successful query is shown here
. If one of the paths don't work the Upload control won't be able to upload the selected files.
