我在实现ajax控件工具包文件上传时遇到一些困难。这就是我要提出的,以下是我的代码。我很抱歉使用VB,我被迫。如果您知道C#解决方案,请提供它,我将转换代码。谢谢
<%@ 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>
背后的代码
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

永远不会调用您的UploadComplete方法,因为它永远不会被处理。像这样添加控件的UploadComplete事件:
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
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,我相信您获得的错误与未设置 HTTP处理程序有关。否则,请指明错误。
直接从ajaxtoolkit网站上的样本:
AjaxFileUpload控件使用名为的HTTP处理程序 AjaxFileUploadHandler.axd此处理程序具有类型 AjaxControlToolkit.AjaxFileUploadHandler。您必须将此处理程序添加到 您的Web.Config文件,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>

您必须在web.config中添加以下内容才能使其正常工作。
<system.web>
....
<httpHandlers>
<add verb="*" path="AjaxFileUploadHandler.axd"
type="AjaxControlToolkit.AjaxFileUploadHandler,
AjaxControlToolkit"/>
</httpHandlers>
</system.web>
