Hello,
Can you explain in more detail what you are trying to accomplish ?

Do you simply want a button to link to a file ?
For example

<asp:Button id="btnDownload" runat="server" OnClick="btnDownload_Click"/>

public void btnDownload_Click(object source, EventArgs e)
{
   Response.Redirect("url_to_the_file_you_want");
}

Or did you have something else in mind?

Hi,

If I understand it right, you want to download a file (not open it) when you click a button. Check this out:

---------------------------------------------------------
string URL = @" FileInfo" target=_blank>http://.../myFileToDownload.txt";
FileInfo fileInfo = new FileInfo(URL);

if (fileInfo.Exists)
{
 Response.Clear();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name);
 Response.AddHeader("Content-Length", fileInfo.Length.ToString());
 Response.ContentType = "application/octet-stream";
 Response.Flush();
 Response.WriteFile(fileInfo.FullName);
}
---------------------------------------------------------

Sorry, the previous message has been screwed up (weird forum...):

---------------------------------------------------------
string URL = "your_url";
FileInfo fileInfo = new FileInfo(URL);

if (fileInfo.Exists)
{
 Response.Clear();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name);
 Response.AddHeader("Content-Length", fileInfo.Length.ToString());
 Response.ContentType = "application/octet-stream";
 Response.Flush();
 Response.WriteFile(fileInfo.FullName);
}
---------------------------------------------------------
