Your UploadComplete method will never be called because it is never handled. Add the UploadComplete event of the control like so:
Protected Sub UploadComplete(sender As Object, e As AjaxControlToolkit.AjaxFileUploadEventArgs) Handles AjaxFileUpload1.UploadComplete
Dim path As String = Server.MapPath("Files/") + e.FileName
AjaxFileUpload1.SaveAs(path)
End Sub
Since the file upload control is only saving the file to a temp location at this point since your handler is never called, I believe the error you're getting is related to not setting an HTTP handler . Otherwise, please specify the error.
Straight from the sample on the ajaxtoolkit site:
The AjaxFileUpload control uses an HTTP Handler named AjaxFileUploadHandler.axd This handler has the type AjaxControlToolkit.AjaxFileUploadHandler. You must add this handler to your Web.Config file in order for the AjaxFileUpload control to work.
Here's the Web.Config configuration that you must add:
<httpHandlers> <add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </httpHandlers>For IIS7:
<validation validateIntegratedModeConfiguration="false" /> <handlers> <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </handlers>

You must add the following in web.config to make it work.
<system.web>
....
<httpHandlers>
<add verb="*" path="AjaxFileUploadHandler.axd"
type="AjaxControlToolkit.AjaxFileUploadHandler,
AjaxControlToolkit"/>
</httpHandlers>
</system.web>
