单击上载按钮后，AjaxFileUpload显示红色错误 [英] AjaxFileUpload displaying Red error after Upload button clicked

问题描述

我遇到了能够拖放图片的 AjaxFileUpload 的问题。点击上传后，文件不会上传，并在文件旁边显示红色的错误消息。



非常感谢，如果有人可以提供解决方案。

下面是我的代码片段。



.aspx page

 <   ajaxToolkit：AjaxFileUpload   
   
                   id   =  ajaxUpload1  
   
                    önUploadComplete  =  ajaxUpload1_OnUploadComplete  
   
                   ThrobberID   =  MyThrobber  
   
                   MaximumNumberOfFiles   = < span class =code-keyword> 1  
   
                < span class =code-attribute>   AllowedFileTypes   =  jpg，jpeg，gif，png  
   
              < span class =code-attribute>       runat   =  server      /  >  
 
 <   asp：图像  
   
                           id   =  MyThrobber  
   
                  < span class =code-attribute>         ImageUrl   = 〜/ images / ajax-loader.gif  
   
                          样式  =   display：None  
   
                           runat   =  server    /  >  

.cs

 受保护  void  ajaxUpload1_OnUploadComplete（ object  sender，AjaxControlToolkit.AjaxFileUploadEventArgs e）
 {
  //  生成文件路径 
  string  filePath =   〜/ images / + e.FileName; 
 
  //  将上传文件保存到文件系统 
 ajaxUpload1 .SaveAs（MapPath的（文件路径））; 
} 

解决方案

将以下内容添加到您的web.config中：

 <   system.webServer  >  
 <  处理程序 >  
 <   add    名称  = < span class =code-keyword> AjaxFileUploadHandler   动词  =  *   路径  =  AjaxFileUploadHandler.axd    type   =  AjaxControlToolkit.AjaxFileUploadHandler，AjaxControlToolkit    /  >  
 <   / handlers  >  
 <   / system.webServer  >  

Hi,

I am having problem with the AjaxFileUpload that enables dragging and dropping of images. Upon clicking "Upload" the file does not upload and shows a red "error" message by the side of the file.

Would greatly appreciate, if someone can provide the solution to it.
Below is a snippet of my code.

.aspx page

<ajaxToolkit:AjaxFileUpload

        id="ajaxUpload1"

         önUploadComplete="ajaxUpload1_OnUploadComplete"

        ThrobberID="MyThrobber"

        MaximumNumberOfFiles="1"

        AllowedFileTypes="jpg,jpeg,gif,png"

         runat="server"  />

        <asp:Image

            id="MyThrobber"

            ImageUrl="~/images/ajax-loader.gif"

            Style="display:None"

            runat="server" />

.cs

protected void ajaxUpload1_OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
    // Generate file path
    string filePath = "~/images/" + e.FileName;

    // Save upload file to the file system
    ajaxUpload1.SaveAs(MapPath(filePath));
}

解决方案

Add the following to your web.config:

<system.webServer>
  <handlers>
    <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit" />
  </handlers>
</system.webServer>
