在浏览器保存对话框中显示 Response.Binarywrite 或打开新窗口并在保存后关闭

我的问题看起来像这样。我有一个包含文档（Id）的网格。现在，当有人单击一行时，我希望允许他下载或显示该文档。但为了让它更简单，我们假设我会通过单击按钮来完成此操作。我尝试了两种方法，但对我来说都不起作用。

我尝试在按钮上单击response.binarywrite：

 Response.Clear();
        Response.ClearHeaders();
        Response.ClearContent();
        Response.ContentType = "应用程序/postscript mime";
        Response.AddHeader("内容处置", "附件; filename=test.ps"); 
        Response.AddHeader("内容长度", _excuteGetDocumentResult.Length.ToString());
        Response.ContentEncoding = new System.Text.UTF8Encoding();
        Response.BinaryWrite(_excuteGetDocumentResult);

但是没有任何反应，当我尝试修改此代码时，我通常会收到一些 javascript 错误，说明有关更改响应的内容...

第二种方法正在打开新窗口并在页面加载时添加上面的代码。

<asp:Button Text="ShowResult" OnClientClick="radopen('ShowResult.aspx','ShowDocumentDialog'); return false;"
        runat="server" />

第二种方法有效，但在保存或取消资源管理器保存文件对话框窗口后，我打开的窗口仍然存在。我尝试添加一些 javascript 来关闭它，但它仅在加载页面上没有 response.binarywrite 的情况下有效...

有什么想法可以实现我想要的吗？

My problem looks like this.
I have a grid with documents (Id's). Now when somebody clicks at a row I would like to allow him to download or show that document. But to make it esier let's say that I would do this on a button click. I tried two approaches but none of them worked form me.

I tried to response.binarywrite on the button click:

        Response.Clear();
        Response.ClearHeaders();
        Response.ClearContent();
        Response.ContentType = "application/postscript mime";
        Response.AddHeader("content-disposition", "attachment; filename=test.ps"); 
        Response.AddHeader("content-length", _excuteGetDocumentResult.Length.ToString());
        Response.ContentEncoding = new System.Text.UTF8Encoding();
        Response.BinaryWrite(_excuteGetDocumentResult);

But nothing happens and when I try to modify this code I usually get some javascript errors saying sommething about changing the response...

The socond approach was opening new window and on page load adding the code above.

<asp:Button Text="ShowResult" OnClientClick="radopen('ShowResult.aspx','ShowDocumentDialog'); return false;"
        runat="server" />

The socond approach works but my opened window still exists after saving or canceling the explorer saving file dialog window. I tried to add some javascript to close it but it only works where there is no response.binarywrite on the load page...

Any ideas how I can achive what I want?
