Answer 1

ASP.NET's "AJAX" thing doesn't support file uploads in UpdatePanels out of the box. Change that trigger into a PostBackTrigger (which causes a full page load) or use something else to upload the file.

Answer 2

Add a trigger for your UpdatePanel

<Triggers> 
   <asp:PostBackTrigger ControlID="btnUploadFile" /> 
</Triggers> 

This will force a postback when the upload button is clicked.

Also add the line below to the Page_Load

Page.Form.Attributes.Add("enctype", "multipart/form-data"); 

Answer 3

I know this post if old, but I found that if the file is empty [ 0 KB ] then it will return false as well. There has to be something in the file in order for .HasFile to acknowledge it.
