ASync Upload - Is this a bug ??

[Seabus]

Hi,

I have an ASync Upload on a web page and the only property manually added to it is to restrict the maximum number of files to 1. (  MaxFileInputsCount="1" )

I discovered some sort of issue  and here's how to replicate : (1) Open an Excel File and leave it open - don't close it (2) Select that same Excel file for upload via the Telerik ASync Upload control (3) Remove the file  from the Telerik ASync Upload Control using the Remove button---> The result is that the Telerik control seems to totally disappear from the page and this is very bad:-)

Any clue on what's going on ? I'm pretty sure this is a bug.

P.S - I'm pretty sure I'm using the latest version

Hello Seabus,

We are aware of that issue. It appears when the Flash module is used to upload files and the uploaded file is invalid. The issue will be fixed in the next release - Q2 2011.
To avoid the issue, please use the following workaround to disable the Flash module:

Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; };

Hi Peter,

I'm glad that you are aware of this issue...
Could you provide some guidance on where I have to insert that JavaScript line of code ?
I'm good at ASP.NET and C# ..not that much into JavaScript

Hi Seabus,

Please place the script declaration after the closing form tag </form>. E.g. :

</form>

<script type="text/javascript">

 Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function ()
{ return false; };

</script>

Best wishes,

Hi,

The only issue is that my <form> begins and ends in the master page.
If I put your code snippet after </form> in my master page I get this error:
Microsoft JScript runtime error: 'Telerik' is undefined

The page where I have my telerik upload control has no form tag :-)
So what should I do ?

Hello Seabus,

Please put the sample code below into RadScriptBlock at the and of the content page. E.g.:

<asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server">
    </telerik:RadAsyncUpload>
    <telerik:RadScriptBlock runat="server" ID="RadScriptBlock1">
        <script type="text/javascript">
            Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () { return false; };
        </script>
    </telerik:RadScriptBlock>
</asp:Content>

All the best,
