Solved this by putting the following into the createEverPresentRowWidget block:
var buttonTag = $(“<input type=’button’ value=’Add’ style=’margin: 2px; id=’jqxButton’></input>”).appendTo(htmlElement);
buttonTag.jqxButton({ width: 70, height: 25 }).on(‘click’, function () { //Add button props (EverPresentRow)
var offset = $(“#jqxGridMisc1099”).offset();
$(“#popupWindow”).jqxWindow({ position: { x: parseInt(offset.left) + 60, y: parseInt(offset.top) + 60 } });
// get the clicked row’s data and initialize the input fields.
var dataRecord = $(“.ToCopyTo”);
$(“#Conclusion”).val(dataRecord.val());
// show the popup window.
$(“#popupWindow”).jqxWindow(‘open’);
