*Global variable
isExport = false;
data-bind="source: dataSource,events:{excelExport : onExcelExport}"
onExcelExport: function (e) {
var sheet = e.workbook.sheets[0];
for (var rowIndex = 1; rowIndex < sheet.rows.length; rowIndex++) {
var row = sheet.rows[rowIndex];
for (var cellIndex = 0; cellIndex < row.cells.length; cellIndex++) {
if (cellIndex === 6 || cellIndex === 8 || cellIndex === 20)
row.cells[cellIndex].format = "HH:mm"
}
}
var gridcolumn = e.sender.columns;
if (!isExport) {
$.each(gridcolumn, function (index, value) {
if (value.hidden)
e.sender.showColumn(index);
else if (value.hidden === false)
e.sender.hideColumn(index);
e.sender.hideColumn(0);
});
e.preventDefault();
isExport = true;
setTimeout(function () {
e.sender.saveAsExcel();
});
} else {
$.each(gridcolumn, function (index, value) {
if (value.hidden === false)
e.sender.hideColumn(index);
else
e.sender.showColumn(index);
});
isExport = false;
}
