    After upgrading to version 2010.1.316.35 of the Silverlight 4 control suite, I am now receiving the "Empty Data Stream" error whenever I upload a file using the RadUpload control in my solution. This used to workout without a problem. I've tried this within the debug mode of VS2010 and outside of VS2010 with the same result. I attempted to upload the same files using the RadUpload sample that came with the installation, and that worked fine, so I don't believe that it's a problem with the file or the control. I confirmed that the target folder has the correct permissions and I confirmed that the "UploadHandler.ashx" is accessible via the browser. I've tried both IE7 and Firefox 3.6 without success. Where else can I start troubleshooting the "Empty Data Stream" error?


    Solution: After upgrading, the reference to the Telerik.Windows.Radupdaterhandler.dll was out of date in the Web project. After deleting the reference and re-adding it, it worked fine.

    Hello josh,

    Thank you for contacting us.

    Recently we updated the upload control. We suppose that the issue relates to this update. However there should not be any errors if you re-reference both the client application and server-side upload handler.

    The other possible source is mixing a Silverlight 4 application with RadControls for Silverlight 3 and vice versa. Please check that version of the RadControls' assemblies coincides with the application version.

    Please try the suggested points and let us know if you need further assistance.

    Sincerely yours,
    the Telerik team
