Hi pranjali, I am not sure for which javascript function you are talking about but i think it is the same i mentioned below. Please try these changes: function previewPdf() { var formData = $( "#rfd03form" ).serialize(); $.ajax({ url: '/RFD03/generatePDF_rfd03_preview' , data: formData, type: 'POST' , success: function (response) { alert(response.pdfDoc); //var w = window.open('about:blank'); //w.document.open(); //w.document.Clear(); //w.document.Buffer = true; //w.document.ContentType = "application/pdf"; //w.document.Cache.SetCacheability(HttpCacheability.NoCache); //w.document.write(response.pdfDoc); //w.document.BinaryWrite(response.bytes); //w.document.close(); //alert(response.pdfDoc); Response.Clear(); Response.Buffer = true ; Response.ContentType = "application/pdf" ; Response.AppendHeader( "content-disposition" , "attachment; filename=" + "RFD03" + "-ViewPDF.pdf" ); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Write(response.pdfDoc); Response.BinaryWrite(response.bytes); Response.End(); // window.open("data:application/pdf;base64, " + response.base64Pdf); }, error: function () { alert( 'Error occured' ); } }); return false ; } You may refer to: https://stackoverflow.com/questions/17797053/how-to-pass-formcollection-using-ajax-call-to-an-action/17797237 https://www.aspsnippets.com/Articles/Submit-POST-FormData-to-Controller-using-jQuery-AJAX-in-ASPNet-MVC.aspx
