Imports System.Web.Script.Serialization
Imports AjaxControlToolkit
Public Class WebForm2
Inherits System.Web.UI.Page
Protected Sub UploadComplete(sender As Object, e As AjaxControlToolkit.AjaxFileUploadEventArgs)
Dim path As String = Server.MapPath("Files/") + e.FileName
AjaxFileUpload1.SaveAs(path)
End Sub
End Class

Your UploadComplete method will never be called because it is never handled. Add the UploadComplete event of the control like so:
您的 UploadComplete 方法永远不会被调用，因为它永远不会被处理。添加控件的 UploadComplete 事件，如下所示：
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.
由于文件上传控件此时仅将文件保存到临时位置，因为您的处理程序从未被调用过，我相信您遇到的错误与未设置HTTP 处理程序有关。否则，请指定错误。
Straight from the sample on the ajaxtoolkit site:
直接来自 ajaxtoolkit 站点上的示例：
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>
AjaxFileUpload 控件使用名为 AjaxFileUploadHandler.axd 的 HTTP 处理程序。该处理程序的类型为 AjaxControlToolkit.AjaxFileUploadHandler。您必须将此处理程序添加到您的 Web.Config 文件中，以便 AjaxFileUpload 控件工作。
这是您必须添加的 Web.Config 配置：
<httpHandlers> <add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </httpHandlers>对于 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.
您必须在 web.config 中添加以下内容才能使其工作。
<system.web>
....
<httpHandlers>
<add verb="*" path="AjaxFileUploadHandler.axd"
type="AjaxControlToolkit.AjaxFileUploadHandler,
AjaxControlToolkit"/>
</httpHandlers>
</system.web>
