Howdy,
No probs. Different type of content cannot be mixed (well in theory it can,
anyone interested have a look at this topic:
http://groups.google.co.uk/group/mi...mixed+with+html&rnum=3&hl=en#c48b66ab6b35e3db)
therefore, you must use an iframe inside your main document that will serve
file as in following example:
-- main page aspx code --
<iframe runat="server" id="whatever" src="download.aspx?fileid=123"></iframe>
-- end --
-- download.aspx c# code behind --
public partial class Download : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// get the file path from query string id
// be careful what you serve, do not allow
// any file to be available
// in my example i added jpeg image copied
// to the application's root folder
string filePath = Server.MapPath("~/sunset.jpg");
System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", String.Format("attachment;
filename=\"{0}\"", filePath));
Response.AddHeader("Content-Length", fileInfo.Length.ToString());
Response.WriteFile(filePath);
Response.End();
}
}
-- end --
Done.
Hope this helps
