Hi, I am playing around with the demo.  Why does the control need to be in an UpdatePanel?  I would have thought that if my browser supports html5 (latest chrome) then the control will send the file back to the server via ajax?  But if I remove the UpdatePanel I can see that there is a postback happening?  Can you explain this behaviour?

Regards,

Chris.

Hi chriswarr2,

The ajax function is based on the ajax control, like the UpdatePanel. So it is necessary.

Hi, I'm not really sure what you're saying, I thought that the html5 FormData object could be used to provide a file upload without a postback, ie. using true ajax?  Is there a reason you don't use the FormData object?
