How can I pass the datatable parameter to my controller for my crystal report for saving file name with parameters of the table in ASP.Net MVC?

Question

I want to pass my javascript datatable data to my crystal report controller to save my filename with employeename and date from datatable. How can I do that? For example. I will save it with a filename named as

Payroll-08292020-Lastname

This is my datatable script.

  var dataTable;
    $(function () {
        dataTable = $('#payrollTable').DataTable({
            "ajax": "@Url.Action("getdata", "payroll")",
            "scrollX": true,
            "columns": [
                { "data": "EmployeeName" },
                { "data": "ShiftName" },
                {
                    "data": "StartDate", "render": function (value) {
                        if (value === null) return "";
                        return moment(value).format('DD/MM/YYYY');
                    }
                },
                {
                    "data": "EndDate", "render": function (value) {
                        if (value === null) return "";
                        return moment(value).format('DD/MM/YYYY');
                    }
                },
                {
                    "data": "PayDate", "render": function (value) {
                        if (value === null) return "";
                        return moment(value).format('DD/MM/YYYY');
                    }
                },

                { "data": "DoubleHolidayOTDaysWork" },
                { "data": "DoubleHolidayOTTotal" },
                { "data": "DoubleWithRestdayOTDaysWork" },
                { "data": "DoubleWithRestdayOTTotal" },

                { "data": "OtherDeductionsTotal" },
                { "data": "LeaveDays" },

                        return "<a class='btn btn-default btn-sm' onclick=edit(" + data + ")><i class='fa fa-pencil'></i>Edit</a>&nbsp;<a class='btn btn-default btn-sm' onclick=printpreview(" + data + ")><i class='fa fa-print'></i>Print Payslip</a>"

            ],
            "language": {
                "emptyTable": "No data found"
            }
     });

and this is my function to trigger printpreview in datatable.

   function printpreview(id)
    {
        window.location.href = "@Url.Action("export", "payroll")?id=" + id;
    }

This is my controller for crystal report.

public ActionResult Export(int? id)
{
    ReportDocument rd = new ReportDocument();
    rd.Load(Path.Combine(Server.MapPath("~/Reports/CrystalReportPayroll.rpt")));
    rd.SetDataSource(db.Payrolls

Try this:

in your View:

  
  
 
   
 
    
    <script>var url_reports = "@Url.Action("Export", "Payroll")"</script>
 
   
 
  

in your JS script:

  
  
 
   
 
    
function printpreview(id)
    {
        window.open(url_reports + "/" + id);
    }
    
 
   
 
  

In your RouteConfig make sure that you have this:

routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

Or create a custom route for you controller

routes.MapRoute(
            "ExportPayroll",
            "Payroll/Export/{id}",
            new { controller = "Payroll", action = "Export", id = UrlParameter.Optional }
        );
