Script Error after upgrade to Q2 dlls

[Geoff Ballard]

Hi,

I have a telerik:RadAsyncUpload in a page.  It worked using the Q1 dll's when I upgraded to Q2 for the multi upload I got a script error.

The error is: "Object doesn't support this property or method"

The error is in a JavaScript resource delivered by Telerik.Web.UI.WebResource.  The header comment is:
/* START Telerik.Web.UI.AsyncUpload.RadAsyncUpload.js */

In line :

w.setFileFilters([],k.get_multipleFileSelectionEnabled()

I'm using the .NET 4 dll's.

Any ideas where I can start looking to solve this?

Hello Geoff,

Could you please send us the definition of RadAsyncUpload and explain exactly how to reproduce the issue? Thanks in advance

Hi,

There's no easy way to provide a full listing as this is used inside a solution with 36 projects.  I've pasted the async markup below.  This is contained inside an updatepanel.  We're using a telerik:RadScriptManager.  I'm using the 2010 Q2 dll's.  How do I determine the exact version I'm using?

If you're unable to replicate this problem is there any particular part of the web.config or something else you'd like to see?  I tried to recreate the problem in a simple project, but multiple file upload worked when I did that.

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
    ReloadOnShow="true" runat="server" Skin="Default" EnableShadow="true">
    <Windows>
        <telerik:RadWindow ID="RadWindowUpload" runat="server" Title="Upload Documents" Modal="true"
            Width="550" Height="400" VisibleOnPageLoad="false" Behaviors="Close" Left="580"
            Top="-8" EnableShadow="true">
            <ContentTemplate>
                <telerik:RadProgressManager runat="server" ID="RadProgressManager1" />
                <telerik:RadAsyncUpload ID="RadAsyncUpload1" MultipleFileSelection="Automatic" runat="server">
                </telerik:RadAsyncUpload>
                <telerik:RadProgressArea runat="server" ID="RadProgressArea1">
                </telerik:RadProgressArea>

The solution where the problem exists did originally use the Q1 dll's so I thought it might be an upgrade issue.  As the error occurs inside the Telerik JS file is it possible that the resource handler is returning an out of date JS file?

Thanks,

[Geoff Ballard]

I was using version: 2010.2.826.40

Hello Geoff Ballard,

I believe that this is an issue with the flash object not being properly recreated after an async postback. We will research the issue and provide a fix for it in the upcoming Q3 release. Meanwhile, If you manage to isolate the problem it would of a great use to us If you provide us with a sample demonstrating it. As for a possible workaround to this problem, please add the following JavaScript after script manager declaration:

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

Sincerely yours,

Hi,

Thanks for the reply; I will give that suggestion a try shortly.  I have managed to recreate this problem in a small project that I'm not authorised to attach to this post so I will create a support ticket and put the zip file there.

Thanks,
