选择下拉项后如何打开其他目录文件夹 [英] How to open a different directory folders after selecting dropdown item
问题描述
海，
我对文件上传有一些疑问.假设是否有一个下拉列表，一个文件上传控件和一个按钮.如果我们选择一个特定的项目并单击文件上传，它应该转到一个本地目录(例如C:/Tally /...).然后选择第二个项目，然后单击文件上传，它应该进入另一个目录(例如D:/Folder/...).我们该怎么做.我使用javascript进行了尝试.不可能.请与我分享如何执行此操作.
以下是示例代码
Hai,
I have some doubts in file upload.Suppose if there is one drop down list,one file upload control and a button.If we select a particular item and click on file upload it should go to one local directory(For eg C:/Tally/...).Then select the second item and click on file upload it should go another directory(For eg D:/Folder/...).How can We do this.I tried it by using javascript.But it''s not possible.Plz share me how to do this.
Below is a sample code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table align="center">
<tr>
<td>
Restrict File Upload sample <br />
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>

<asp:ListItem>5</asp:ListItem>
</asp:DropDownList>
<asp:FileUpload ID="FileUpload1" runat="server" />
<br />
<asp:Button ID="Button1" runat="server" Text="Button" />
<br />
<asp:Label ID="Label1" runat="server" ForeColor="Red"></asp:Label>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>

推荐答案
就像我昨天说的那样，您必须在服务器端代码(而不是javascript)中处理此问题，因为上传控件不会在任何地方存储任何内容.
返回MSDN，查看文件上传控件 [ ^ ]并阅读通过链接.他们甚至为您提供了示例-尝试跟随它们...
As I said yesterday, you have to handle this in Server side code - not javascript - as the upload control does not store anything anywhere.
Go back to MSDN, look at the FileUpload control[^] and read through the links. They even give you examples - just try following them...
