So you are already putting your file in DB?

To allow users download file you should use Response.BinaryWrite. You will also need to send some special headers to user.

All in all the code looks like this:

  Response.ContentType = "Application/pdf";
  Response.AppendHeader( "content-disposition", "attachment; filename=" + name );
  Response.BinaryWrite(data);
  Response.End();

Pass the file to the response stream with the appropriate content type set. Then the browser will open a dialog to save or open the document.
