Answer 1

A small example using rotativa package in asp.net mvc

We will create a function to populate the data. We will insert data for 7 days (Feb 1 2018 - Feb 7 2018) showing the first punch and the last punch for particular day with remarks.

public ReportViewModel PopulateData()
        {
            var attendances = new List
            {
                new Attendance{ClassName = "present",Day = new DateTime(2018, 02, 01).ToString("ffffd"),Date = new DateTime(2018, 02, 01).ToString("d"),FirstPunch = "09:01:00",LastPunch = "06:00:01",Remarks = ""},
                new Attendance{ClassName = "absent",Day = new DateTime(2018, 02, 02).ToString("ffffd"),Date = new DateTime(2018, 02, 02).ToString("d"),FirstPunch = "",LastPunch = "",Remarks = "Absent"},
                new Attendance{ClassName = "holiday",Day = new DateTime(2018, 02, 03).ToString("ffffd"),Date = new DateTime(2018, 02, 03).ToString("d"),FirstPunch = "",LastPunch = "",Remarks = "Democracy Day"},
                new Attendance{ClassName = "present",Day = new DateTime(2018, 02, 04).ToString("ffffd"),Date = new DateTime(2018, 02, 04).ToString("d"),FirstPunch = "09:05:00",LastPunch = "06:30:01",Remarks = ""},
                new Attendance{ClassName = "present",Day = new DateTime(2018, 02, 05).ToString("ffffd"),Date = new DateTime(2018, 02, 05).ToString("d"),FirstPunch = "09:01:00",LastPunch = "06:00:01",Remarks = ""},
                new Attendance{ClassName = "leave",Day = new DateTime(2018, 02, 06).ToString("ffffd"),Date = new DateTime(2018, 02, 06).ToString("d"),FirstPunch = "",LastPunch = "",Remarks = "Sick Leave"},
                new Attendance{ClassName = "present",Day = new DateTime(2018, 02, 07).ToString("ffffd"),Date = new DateTime(2018, 02, 07).ToString("d"),FirstPunch = "08:35:00",LastPunch = "06:15:01",Remarks = ""}
            };


            return new ReportViewModel
            {
                UserInformation = new UserInformation
                {
                    FullName = "Ritesh Man Chitrakar",
                    Department = "Information Science"
                },
                StartDate = new DateTime(2018, 02, 01),
                EndDate = new DateTime(2018, 02, 07),
                AttendanceData = attendances
            };
        }

We will then create a function to DownloadPdf. To download the pdf we will need to create 2 function. 1. to download pdf 2. to view pdf

public ActionResult DownloadPdf()
        {
            var filename = "attendance.pdf";

            /*get the current login cookie*/
            var cookies = Request.Cookies.AllKeys.ToDictionary(k => k, k => Request.Cookies[k]?.Value);

            return new ActionAsPdf("PdfView", new
            {
                startDate = Convert.ToDateTime(Request["StartDate"]),
                endDate = Convert.ToDateTime(Request["EndDate"])
            })
            {
                FileName = filename,
                /*pass the retrieved cookie inside the cookie option*/
                RotativaOptions = {Cookies = cookies}
            };
        }

public ActionResult PdfView()
        {
            var reportAttendanceData = PopulateData();

            return View(reportAttendanceData);
        }
