C#:在更新面板中打开/保存对话 [英] C#: Open/Save Dialogue inside Update Panel

问题描述

我已经在asp.net的更新面板中使用过打开/保存对话框，但是由于以下代码行而无法正常工作:

I have used open/save dialog box inside update panel in asp.net but it is not working because of the code line:

Response.WriteFile(path);

我可以使用其他任何东西通过打开/保存对话框打开文件.
我打开文件的代码:

Can I use any thing else for opening a file through open/save dialog box.
My code for opening the file:

Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.AppendHeader("content-disposition","attachment; filename=" + name);
Response.ContentType = "Application/msword";
Response.WriteFile(path);
Response.Flush();
Response.Close();
Response.End();

推荐答案

您是要保存文件到客户端还是服务器? Response.WriteFile不是您要使用的.尝试Response.TransmitFile，但我不确定您是否真的需要/想调用Flush，Close或End.

Are you trying to save a file to the client, or to the server? Response.WriteFile isn''t what you want to use. Try Response.TransmitFile, and I''m not sure your really need/want to call Flush, Close, or End.

您需要按钮来引起全部回发，而不是部分回发.即

You need the button to cause a full postback rather than a partial. i.e.

<Triggers>
    <asp:PostBackTrigger ControlID="btnFileUpload"/>
</Triggers>

将此添加到您的page_Load()事件

Add this to your page_Load() Event

ScriptManager.GetCurrent(this).RegisterPostBackControl("Your Control id(want to open file dialogue when click)");
