ASP.NET MVC - Download PDF file in same window not working

Question

I have download PDF file(not to open) generated from controller method. file is getting opened in new separate window. I am generating MemoryStream at server side. I have to return it to client in same window, here I don't have to open, just download in the same client window. below code I have tried -

Server-

public async Task<ActionResult> DownloadReport(string id, string reportType="")
{
  var fileData = await GetReport(id, reportType); 
  // here fileData is MemoryStream

  return  File(fileData, "application/pdf");
}

html code -

 @Html.ActionLink("Download", "DownloadReport","Files", new { id = "abc" },null)

Answer 1

Use Content-Disposition header

   public async Task<ActionResult> DownloadReport(string id, string reportType="")
    {
      var fileData = await GetReport(id, reportType); 
      // here fileData is MemoryStream
      Response.AddHeader("Content-Disposition", "attachment;filename=file.pdf");
      return  File(fileData, "application/pdf");
    }
