Depending on how you have your page set up, you may be able to use the
"Content-Disposition" header (example below). There are plenty of full
examples available via google. Adding the line below to your aspx (or code
behind, which ever method you're using) will cause the browser to
automatically pop up the open/save dialog box.
// sample only, read up on this to ensure you can use it
Response.AddHeader("Content-Disposition", "attachment; filename=List.csv");
