ajax文件上传器无法正常工作 [英] ajax file uploader not work

问题描述

我使用ajax文件上传器：

i use ajax file uploader:

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
  </asp:ToolkitScriptManager>
  <div>
      <asp:AsyncFileUpload ID="AsyncFileUpload1" runat="server"

          onuploadedcomplete="AsyncFileUpload1_UploadedComplete" />
      <asp:Image ID="Image1" runat="server" />
  </div>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

At代码背后：

At Code Behind:

AsyncFileUpload1_UploadedComplete
{
string path = Server.MapPath("~/Upload/") + e.FileName;
        AsyncFileUpload1.SaveAs(path);

        Image1.ImageUrl= "~/Upload/" + e.FileName;
 Label1.Text="/Upload/"+ e.FileName;

}

但是图片没有显示在image1控件中，

和label1也没有显示任何文字：



所以我能做什么：

i想要，当用户上传图片时，然后没有刷新页面，

图像显示在Image1控件中，



我认为当UploadedComplete事件调用它时不会重写整页，所以图像和标签是空白

But Image is not shown in image1 control,
and label1 also not shown any text:

so what can i do:
i want that, when user upload image, then with out refresing page,
image is show in Image1 control,

I think that when UploadedComplete Event called it not refress full page,so image and label is blank

推荐答案

听起来像是一个相对路径问题。



有一种方法可以处理URL''。阅读： ResolveUrl [ ^ ]。



我建议您在设置控件/图像源之前使用此提示并正确解析路径：解决多文件夹网站中的路径 [ ^ ]

Sounds like it is a relative path issue.

There is a method exposed to handle URL''s. Have a read: ResolveUrl[^].

I would suggest you to use this Tip and resolve the path correctly before setting the control/image source: Resolving Paths in a Multi-Folder WebSite[^]
