<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm2.aspx.vb" Inherits="AMS.WebForm2" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>

<form id="form1" runat="server">
    <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" />

    <asp:AjaxFileUpload ID="AjaxFileUpload1" runat="server" />
    <asp:Image ID="loader" runat="server"
        ImageUrl="~/loading.gif" Style="display: None" />
</form>
</body>
</html>

Code behind 后面的代码

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

Answer 1

Your UploadComplete method will never be called because it is never handled. 您的UploadComplete方法将永远不会被调用，因为它永远不会被处理。 Add the UploadComplete event of the control like so: 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 . 由于文件上传控件目前仅将文件保存到临时位置，因为从未调用过您的处理程序，因此我认为您遇到的错误与未设置HTTP处理程序有关 。 Otherwise, please specify the error. 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. AjaxFileUpload控件使用一个名为AjaxFileUploadHandler.axd的HTTP处理程序。此处理程序的类型为AjaxControlToolkit.AjaxFileUploadHandler。 You must add this handler to your Web.Config file in order for the AjaxFileUpload control to work. 您必须将此处理程序添加到Web.Config文件中，以便AjaxFileUpload控件起作用。

Here's the Web.Config configuration that you must add: 这是您必须添加的Web.Config配置：
 <httpHandlers> <add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </httpHandlers> 
For IIS7: 对于IIS7：
 <validation validateIntegratedModeConfiguration="false" /> <handlers> <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/> </handlers>

Answer 2

You must add the following in web.config to make it work. 您必须在web.config中添加以下内容以使其起作用。

<system.web>
    ....
    <httpHandlers>
        <add verb="*" path="AjaxFileUploadHandler.axd"
          type="AjaxControlToolkit.AjaxFileUploadHandler, 
          AjaxControlToolkit"/>
    </httpHandlers>
</system.web>
