  • I recommend to return view model that contains file content as byte[] and message (success or false) and pass this model to view and render pdf as part of page reference to this article https://stackoverflow.com/questions/6439634/view-pdf-as-part-of-the-page with showing message on the page or on alert – Mohamed Adel Jan 11 '21 at 09:50
  • @MohamedAdel used view model but getting file response in json format with file and content details.not downloading file and this is a web api and want to download file and need to display message – Dasam Bharathi Jan 11 '21 at 10:42
  • Please add your method with view model to question – Mohamed Adel Jan 11 '21 at 10:49
  • return new Response { Data = new DocVm() { Documents = File(bytes, "application/pdf", DateTime.Now.ToString("ddMMyyyy") + ".pdf"), message = "Ok" } }; and the model is public class DocVm { public FileResult Documents { get; set; public string message{ get; set; } } – Dasam Bharathi Jan 11 '21 at 11:29
  • Just send file content as (byte[]) and handle view or download on frontend layer – Mohamed Adel Jan 11 '21 at 11:54
  • byte[] bytes = Convert.FromBase64String(responseobj.Data.ToString()); if (bytes != null && bytes.Length > 0) { return new Response { Data = new DocVm() { Documents = File(bytes, "application/pdf", DateTime.Now.ToString("ddMMyyyy") + ".pdf"), message = "Ok" } }; please have a look into this im returning like this – Dasam Bharathi Jan 11 '21 at 13:05
  • Don't return file just return bytes directly and manage it at frontend layer. return new Response { Data = new DocVm() { Documents = bytes, message = "Ok" } }; – Mohamed Adel Jan 11 '21 at 13:22
