  I'm currently using the RadAsyncUpload for multiple file upload use.  The control works fine in Chrome, IE, Opera, Firefox, etc, but when i go to select multiple files and upload them in Safari, i get an error (see attached image).  Below is a snippet of my RadAsyncUpload code in my aspx file:
  

  <telerik:RadAsyncUpload ID="Uploader" runat="server" Width="0" Skin="Vista" ToolTip="Choose images to upload." MultipleFileSelection="Automatic" AllowedFileExtensions="jpg,jpeg,png,bmp" AutoAddFileInputs="true" OnClientValidationFailed="ValidateType" OnClientFilesUploaded="CausePostback" OnPreRender="PictureGrid_OnPreRender" OnFileUploaded="UploadFiles_FileUploaded"><Localization Select="Upload Pictures" /></telerik:RadAsyncUpload>

  
  Any idea why i'm getting the following error or how to fix it?
  
  Thanks for the help,
   - Pat

  Update:  I now determine whether or not the user is browsing with Safari.  If they are i disable multiple file selection.  Even when only uploading single images (which are ~850 KB each) the same error occurs.
  
  Any theories/help would be appreciated.

  Have the problem resolved to a point.  My experience regarding this issue:  RadAsyncUpload with Safari using a PC does not work too well (or at all with single/multiple uploading).  Using a Macintosh works only with single file uploading, multiple file uploading also does not work using a Macintosh.

  Hi Pat,
  
  In the latest version of our controls the multiple selection in Safari is disabled, because there is an issue with the implementation of the FileApi interface in Safari (the uploaded file are empty). We already reported that problem to Safari. Please clarify which version of our control are you using?
  The error from the screenshot means that you are trying to refresh the page and your data from it will be resend.
  
  All the best,

  Thanks for the response Peter.
  
  I am currently using version 2011.1.413.40.  I have also tested MultipleFileUpload using a simple page with just a RadAsyncUpload control.  Other browsers (Chrome, FireFox, Opera) are also not working with MultipleFileUpload when using a Macintosh.  Is there a way to determine whether the website is being hit by a Macintosh or not?

  Hello Pat,
   
  I have tested the RadAsyncUpload control under Mac OS 10.7.2 with the mentioned version of our controls, and everything worked as expected. Here is the sample markup that I used:
  
  

  <form id="form1" runat="server">

  <div>

      <telerik:RadScriptManager runat="server" ID="RadScriptManager"></telerik:RadScriptManager>

      <telerik:radasyncupload id="Uploader" runat="server" width="0" skin="Vista" tooltip="Choose images to upload."

          multiplefileselection="Automatic" autoaddfileinputs="true"

          ><Localization Select="Upload Pictures" /></telerik:radasyncupload>

      <asp:Button Text="text" runat="server" />

  </div>

  </form>

  
  Could you please send me a working sample project that demonstrates the issue?
  
  Please review the following post how to detect your machine's operating system.
  
  Kind regards,

  Hey Peter thanks for the response,
  
  I tried out your code and it seemed to work fine.  I'll have to take a look at my code to find the difference.  Thanks again for the help.

  Hi Manesh,
  
  Could you please elaborate on the issue that you get on your machine? If there a server or client side exception? In order to resolve your problem, could you please open a new support ticket and send a pattern to reproduce the issue or a working sample project.
