asp.net mvc 3 - mvc3 and evopdf - display "processing" message while the pdf is being generated -

i using mvc3 , evopdf (http://www.evopdf.com/) create pdf when user clicks on print button.

i have initial view contains form , print button , 2nd view designed printing.

clicking on print button calls javascript submit form, calls print action.

what happen once print button has been clicked, "processing" message displayed. once pdf has been generated message removed.

this javascript (i have not included of javascript there parts not relevant)

$(document).ready(function () {     $(".btn").click(function () {         var delay = 10;          $("#ajaxdelay").val(delay);          $.blockui();         $('#printform').submit();     });      $('#printform').submit(function () {         $.blockui();             $.ajax({             url: this.action,             type: this.method,                       success: function (data) {                 $.unblockui();                 //i need open pdf in appropriate app, adobe pdf viewer or similar             },             failure:function(data) {                 alert("error");                 $.unblockui();             }         });         return false;     });  }); 

the form

@using (html.beginform("printview", "index", new { format = "pdf/", id = model.id,     ajaxdelay = model.ajaxdelay }, formmethod.get, new { id="printform"  })) {     @html.hiddenfor(m=>m.ajaxdelay)              <button type="button" class="btn print" >print</button>         } 

indexcontroller

public actionresult printview(int id) {                var model = getdata(id);     return view(model); } 

this httphandler

public void processrequest(httpcontext context) {     if (!context.request.isauthenticated) return;         producepdf(context, "pdf title", 20); }  private void producepdf(httpcontext context, string title,int delay) {     var pdfconverter = getpdfconverter();      // set license key     pdfconverter.licensekey = "licence key here";     pdfconverter.javascriptenabled = true;      var pdfbytes = pdfconverter.getpdfbytesfromurl(context.request.url.tostring().replace(".pdf/", ""));      // send pdf document response browser download     var response = httpcontext.current.response;     response.clear();     response.addheader("content-type", "application/pdf");     response.addheader("content-disposition", string.format("attachment; filename=" + title + ".pdf; size={0}", pdfbytes.length));     response.binarywrite(pdfbytes);     response.end(); }
