Flash no longer working

[Andrew Dixon]

Hi,

I've been using version 2010.1.315.35 of the ASP.NET AJAX tools for quite some time now.  I'm in the middle of upgrading to the latest version (2012.2.724.35).  I use AsyncUpload in my application and use Flash in my application too.  Up until now version 2010.1.315.35 AsyncUpload has been using Flash in Firefox and Chrome (versions 14.01 and 21.0 respectively) but now that I've upgraded to 2012.2.724.35 flash is no longer being used and it appears to be falling back to using HTML.  I make extensive use of file filters so it's important that I can use AsyncUpload in flash mode.  I've noticed also that the demo at http://demos.telerik.com/aspnet-ajax/upload/examples/async/validation/defaultcs.aspx?product=asyncupload has the same problem.

My AsyncUpload control is specified as follows:

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server"
                                    OnClientFileUploadFailed="RadAsyncUploadOnUploadFailed"
                                    OnClientFileSelected="RadAsyncUploadOnFileSelected"
                                    OnClientFileUploaded="RadAsyncUploadOnFileUploaded"
                                    OnClientFileUploadRemoved="RadAsyncUploadOnUploadRemoved">
                                    <Localization Select="<%$ Resources:Localization, AttachFile %>" />
                                    <Localization Cancel="<%$ Resources:Localization, Cancel %>" />
                                    <Localization Remove="<%$ Resources:Localization, Remove %>" />

Is there something different I need to do in 2012.2 to get flash working?

Thanks

Hello Andrew,

 
If you want to use Flash upload module with the latest version you can add the following code:

<script type="text/javascript">
    Telerik.Web.UI.RadAsyncUpload.Modules.FileApi.isAvailable = function () { return false; }
 Telerik.Web.UI.RadAsyncUpload.Modules.Silvelight.isAvailable = function () { return false; }
</script>

Please have in mind that in spite of the possibility above we strongly recommend using the default FileApi upload module because some errors may occur with some versions of the Flash plug-in.  

As for the File filtering functionality- it is not supported yet under FileApi but one can still only select the desired file extensions despite all the files are seen in the pop up window.

Hope this information will be helpful.
Greetings,
Plamen
