My boss and I reviewed your response to both this forum post and the ticket.
As an experiment, we created a folder in our GoDaddy server that requires no credentials. It still didn't work.
I want to be able to set my RadAsyncUpload control thusly:
<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" TargetFolder="Fake.GoDaddyServer.biz/temp/temp" TemporaryFolder="C:\"></telerik:RadAsyncUpload>
and the file gets uploaded to the GoDaddy server. No code behind. No events.
My boss assures me that back when he used this control's predecessor (the synchronous upload control), this would have worked just fine. So why isn't it working for the asynchronous control?
