I am using VS2010, RadControls for ASP.NET AJAX Q2 2010 with ASP.NET 4.0.

I have the following on my page:
<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" OnClientFileSelected="onFileSelected" OnClientFileUploaded="onFileUploaded" ReadOnlyFileInputs="true">
</telerik:RadAsyncUpload>

When I load my page, I get an error in IE8 in this function:
 
function
__flash__addCallback(instance, name) {
instance[name] = 
 
function () { return eval(instance.CallFunction("<invoke name=\""+name+"\" returntype=\"javascript\">" + __flash__argumentsToXML(arguments,0) + "</invoke>"));
}
}

The Call Function is is try to load is this:
<invoke name="setFileFilters" returntype="javascript"><arguments><array></array><false/></arguments></invoke>

I have tried using the latest internal builds as well as this version and it is the same.

What might be the problem?

Hi Jeff,

I'm not able to reproduce this issue at our side. Could you please send us a runnable page demonstrating the problem? Thanks

It looks like the problem is when I have a Rad Async Upload control in a Panel with a Ajax Control Toolkit RoundCornersExtender applied to it.

<

 

 

asp:RoundedCornersExtender ID="RoundedCornersExtender1" TargetControlID="AddPanel" runat="server" Radius="4" BorderColor="Black" Corners="All">

 

</

 

 

asp:RoundedCornersExtender>

When I remove the this extender, everything works correctly.

Thanks,
--Jeff

Hello Jeff,

Is this panel initially invisible? I'm asking because we have logged similar issue recently.

We're experiencing this issue as well.  The panel containing the RadAsyncUploader is initially NOT visible.

Our application then breaks throwing the error:

Invalid postback or callback argument. Event validation is enabled using

I'm getting exactly the same error as the op.

This only started when I upgraded to the latest version. Before it was working fine (version 2010.1.519).

My upload is also initially not visible.

Any updates on what the issue could be?

Just worked out the issue.
New version uses flash which may cause upload to break in IE. 

Disabled the flash and everything is happy again...

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