and below kendo export chart pdf code, call through loadpdf function.

  function loadpdf() {             try {                                        $("#griddata").show();                                         $("#reportheader").show();                  if ($("#chartdiv").html() != null && $("#griddata").html() != '') {                     settimeout(function () {                     kendo.drawing.drawdom($("#griddata"))                     .then(function (group) {                         // render result pdf file                         return kendo.drawing.exportpdf(group, {                             papersize: "auto",                             margin: { left: "1cm", top: "1cm", right: "1cm", bottom: "1cm" }                         });                     })                     .done(function (data) {                         // save pdf file                         kendo.saveas({                             datauri: data,                             filename: window.sessionstorage.getitem('xxxname') + ".pdf",                             proxyurl: "/account/export"                         });                          $("#reportheader").hide();                                                         $("#griddata").hide();                       });                     }, 2000);                     }             }             catch (e) {                 $("#reportheader").hide();                                        $("#griddata").hide();                      umgeneratealert('error while exporting data');             }             {             }         }

the above method works fine, problem is, before exporting "griddata" div elements pdf, forced enable div. otherwise exported pdf returns no data. causing "griddata" div appear on screen till pdf gets exported , gets hidden once document downloaded.

please suggest me how can handle this, without displaying in ui.

try css print media query:

@media print {   /* print styles go here */     #header, #footer, #nav { display: none !important; }      #griddata, #reportheader { display: block !important; }  }

or old way:

<link href="/print.css" rel="stylesheet" media="print" type="text/css" />

regarding grid part, have tried using visibility: hidden;? since space , dimensions of element preserved.

if you, show overlay layer loading progress bar covers grid area , hide after finish hidding grid.

anyway, display: none still part of dom, i'll update answer if there workaround.
