I am trying to export some content as .csv file as shown in the below code.
function ExportToCSV(gridContent, file_name) {
    if (detectIE()) { // Checks IE and Edge
            var IEwindow = window.open();
            IEwindow.document.write(gridContent);
            IEwindow.document.close();
            IEwindow.document.execCommand('SaveAs', true, file_name + ".csv");
     } else {
          ..... for other browsers.........
     }
  }
I am having issue document.execCommand which is not functioning like it functions in internet explorer, i,e prompting the dialog window to store .csv file internet explorer.
document.execCommand is failing in Edge, What i am missing ?
