  my button Don’t Redirect after use of method " TransmitFile" ) (VS2010 – C#)

  May 30, 2012 07:10 AM|LINK

  Hi

  For download a file I use below code:

   

  if (HttpContext.Current.User.Identity.IsAuthenticated)

              {

   

                  String FilePath = @"~\myfolder\myfile.pdf";

   

                  HttpContext context = HttpContext.Current;

   

                  context.Response.AppendHeader("content-disposition", "attachment; filename= myfile.pdf");

                  context.Response.ContentType = "application/ZipFile";

                  context.Response.TransmitFile(FilePath);

                 

              }

              else

              {

                 

              }

   

  But after do it , below code (a button for Redirect to another page) don’t operate. Why?

   

  try

              {

                  Response.Redirect("~/myfolder/mypage2.aspx?returnUrl= mypage1.aspx");

              }

              catch

              {

                 

              }

  Thanks very much

  for a request you can have only one response so then download file is appended in header the response is to download the file it can do anything to the page, so first redirect then start the download page using ajax or iframe
