asp.net – AjaxFileUpload不会触发OnUploadComplete事件

我使用的是ControlToolkit版本4.1.60919.0.我已经尝试了我在互联网上找到的一切.

这里只需几步：

>在我的MasterPage中的form-element中添加了enctype =“multipart / form-data”method =“post”
>使用UpdateMode = Always将AjaxFileUpload嵌套到UpdatePanel中
>尝试事件UploadedComplete和OnUploadComplete,但保持在第二个
>在EventHandler中添加了try-catch-block以捕获未知异常并将ExceptionMessage打印到站点上的标签 – >没啥事儿
>尝试了(出)一个ThrobberImage ……
>许多其他不起作用的tipps ……

所以,我希望我们能在这个社区中找到一个解决方案.继承我的加价：

<%@ Page Title="New Download" Language="C#" MasterPageFile="~/MasterPage.master"     AutoEventWireup="true" CodeFile="NewDownload.aspx.cs" Inherits="Internals_NewDownload" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="Server">

<ajax:ToolkitScriptManager ID="ToolkitscriptManager" runat="server">    </ajax:ToolkitScriptManager>
<h1>Create a new Download</h1>

        <ajax:AjaxFileUpload ID="FileUpload" runat="server" ThrobberID="ThrobberLabel" OnUploadComplete="FileUpload_UploadComplete" />
        <asp:Label ID="ThrobberLabel" runat="server" Style="display: none;"><img alt="UploadingPicture" title="Please wait while uploading..." src='<%= Constants.DomainString + "/Data/Images/loading-small.gif" %>' /></asp:Label>
        <asp:Label ID="DownloadLabel" runat="server"></asp:Label>

</asp:Content>

这是我的CodeBehind：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Internals_NewDownload : System.Web.UI.Page
{
private string m_LanguageCode;

protected void Page_Load(object sender,EventArgs e)
{
    if (RouteData.Values.ContainsKey("LanguageCode"))
        m_LanguageCode = RouteData.Values["LanguageCode"].ToString();

    //if (IsPostBack)
    //    return;
    if (!User.IsInRole("Administrator") && !User.IsInRole("Kunde") && !User.IsInRole("Mitarbeiter"))
        Response.Redirect(Constants.DomainString + "/PermissionDenied.aspx");
    Session[Constants.NonGlobalizedString] = true;
    Session[Constants.MenuInfoSession] = new ClsMenuInfo("NewDownload");
}

protected void FileUpload_UploadComplete(object sender,AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
    try
    {
        string filePath = "~/upload/" + e.FileName;
        DownloadLabel.Text = filePath;
    }
    catch (Exception ex)
    {
        DownloadLabel.Text = ex.Message;
    }
}
}

如果您有任何想法,请不要犹豫,让我知道.我很困惑,因为我认为我只是在互联网上找到的那些howtos …

提前致谢！
