I have an asp.net application with a page to upload files (csv file). In this page I have an updatepanel in that I have a html fileupload control.
The fileupload works fine with both IE and Firefox. With chrome, I can see the PostedFile.Filename = "bac.csv", PostedFile.InputStream.Length = 80 But when I copy the Inputstream to a byte array, all the bytes have zero value. Remember this same code works fine with other browsers.
Fiddler also shows different postdata. see below for Chrome and Firefox data that I see in Fiddler. Clearly, Chrome is not posting the file data. What I am doing wrong and how can I fix it.
