Closed Issue: Async File Upload [27487]

Hi,

I am not sure if there is a bug somewhere. But, I am unable to get the Async File Upload to work with PopupControl Extender. I keep getting 'Unknown Server Erorr'(http://forums.asp.net/p/1926691/5471748.aspx/1?Re+Ajax+Async+File+Upload+Control+Error+Unknown+Server+Error+ )and not really sure how to troubleshoot this issue. I have posted this into the forums but haven't been able to resolve it through the suggested articles. I really appreciate it if I can get assistance in getting this to work as I will need to have it working soon.

Thanks.
