    });
</script>
controller:
  public ActionResult ExportMasterData(List<string> checkedRowsIndexes)
        {
            if (ModelState.IsValid)
            {
                //workbook creation
                Workbook currentWorkbook = new Workbook();
                ///region
                if (checkedRowsIndexes != null && checkedRowsIndexes.Contains("0"))
                { //export to excel}
if(checkedRowsIndexes.Contains("1"))
{//export to excel}
return View();
}
else
return View();
Export to excel code:
if (checkedRowsIndexes != null && checkedRowsIndexes.Contains("0"))
            {
                var service_region = ObjectFactory.GetInstance<IRegionControllerService>();
                var collection_region = service_region.GetRegionViewModel().ToList();
                Worksheet regionsheet = currentWorkbook.Worksheets.Add("Region");
                foreach (var cell in regionsheet.GetRegion("A1:C1"))
                {
                    cell.CellFormat.FillPattern = FillPatternStyle.Solid;
                    cell.CellFormat.Font.Bold = ExcelDefaultableBoolean.True;
                }
                regionsheet.Rows[0].Cells[0].Value = "Region Name";
                regionsheet.Rows[0].Cells[1].Value = "Region Code";

                    i++;
                }
