RadAsyncUpload problems in Safari

[Pat]

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,

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.

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.

"In the latest version of our controls the multiple selection in Safari is disabled"

It seems that it's still the case in the last version. Can you confirm ?

Hello Arnaud,

I am writing to confirm that MultipleFileSelection under Safari is still disabled. Under Safari RadAsyncUpload control is using FileAPI module to upload files (which is based on FileAPI specification). Safari browser does not implement the interface correctly and that causes issues with multiple selection. We reported the problem and still there is no resolution. As soon the fix is available we are going to enable multiple selection.

"MultipleFileSelection under Safari is still disabled"
Is this behavior still exists.

Hello Paresh,

The issue is resolved by Safari and now it is possible to upload multiple files.

Hi Peter.

We are seeing the same issue on our iPad.  I am thinking out iPad is out of date for Safari and/or the OS.  What version of each do we need to be at in order for this to work?  

Also, we are using Version 2014.3 1209 of your libraries.  Does this version allow multiple files to be uploaded?

Hi James,

File uploading is not possible at all on iOS Safari before iOS 6. And I can confirm that multiple files uploading is expected to work on iOS 7.1 and latest iOS 8.3 Safari. The initial releases of iOS 8 had an issue with multiple files uploading, which was fixed later on by Apple.

You may try to update your device to the latest possible and test if this fixes the issue. The Telerik UI for ASP.NET AJAX version should allow multiple files upload with Safari.

Hi Dimitar.

 I checked on the versions and we are at 8.3.  Is there a specific version of the Telerik libraries that we should be at?

Thanks.

Hi,

I have tested your version with iOS 8.3 and multiple files upload works as expected. There is no other specific version that you should be using. I am sending you the test page that works on my side. It includes a RadAsyncUpload with disabled multiple files upload and a second one with enabled, so you can compare their settings and behavior.

hi

 

all the telerik control is working fine in all browser except safari

Any help

I am using version(2015.1.401.45)

Hi Arwad,

Could you please open a new forum thread for the problem faced, as the current thread is dealing with a specific issue related only to the RadAsyncUpload and Safari browser. Thus, we would keep threads consistent and would provide better support to the community.

It would be helpful if you provide a runnable sample that could be used for issue reproduction or a live URL. And could you check if the issue is reproducible with both iOS 7 and 8 versions or with iOS 8 only.
