Html fileupload control does not upload file in Chrome

I have an asp.net application with a page for downloading files (csv file). On this page, I have an update panel in which I have an html file system control.
Fileupload works great with IE and Firefox. With chrome, I can see that FileFile.Filename = "bac.csv", Added File.InputStream.Length = 80 But when I copy the input stream to an array of bytes, all the bytes are null. Remember that the same code works fine with other browsers.

Fiddler also shows different postdata. see below the Chrome and Firefox data that I see in Fiddler. Obviously, Chrome does not publish file data. What am I doing wrong and how can I fix it.
