RegisterClientScriptBlock不起作用 [英] RegisterClientScriptBlock not working

问题描述

我有一个文件上传控件:

I have a fileupload control:

<asp:FileUpload ID="file" runat="server" Width="100%" />

然后，我在后面的代码中注册了一些JavaScript:

Then I register some javascript in the codebehind:

this.Page.ClientScript.RegisterClientScriptBlock(typeof(string), "file", "<script language=javascript> function BrowseClick() { "
  + "document.getElementById('" + this.file.ClientID.ToString() + "').click(); return false; } </script>");

然后，将函数添加到ASP.NET按钮的属性中:

Then I add the function to the attributes of an ASP.NET button:

this.btnDownload.Attributes.Add("onclick", "BrowseClick");

当我单击此按钮时，我希望打开文件对话框，但是什么也没有发生.为什么?
另外，我希望文件上传以另存为"对话框而不是文件打开"对话框打开.

When I click this button I expect a file dialog to open, but nothing happens. Why?
Also, I want the fileupload to open as a "save as" dialog instead of a "file open" dialog. How can this be done?

推荐答案

看看这篇文章，听起来就像您需要的一样:
使用C#下载文件 [

Have a look at this article, sounds like the same thing you need:
File download using C# [^]

It says, for SaveAs dialog in ASP.NET you need to add these to the response header:

Response.ContentType="application/ms-word";
Response.AddHeader( "content-disposition","attachment; filename=download.doc");
