Actually, we are aware of all these issue, but they are hard to resolve
as the control uses fake input element to provide fancy skinning.
Anyway, we are doing our best to address these issues and most probably
will do so in some of the next versions of the control.
As for the "fakepath" in the URL string,
this is not a bug with IE8 or RadUpload, but a security consideration.
According to the specifications of HTML5, a file upload control should
not reveal the real local path to the file you have selected, if you
is returned by the script, which handles the file information is
This requirement is already implemented in Internet Explorer 8 and the
real path to the file will be shown only if the page that contains the
control is added to the trusted sites collection of the browser, and
this is why you get such string in IE8.
