Hello!

I have a challenge i want to solve.

I have a main report with a list, which contains a subreport. I set the list datasource to a table which generates dates from which the user have selected. Sometimes it is just 1 date, or the user can select a range from which is no limitations. So it can be 5 dates, 10 dates or 100 dates.

So far everything is good an the list gets on row pr date. So when the subreport is inside the list it also generates a subreport pr date.

I am using void LocalReport_SubreportProcessing and it gets fired one time pr date. I have then added logic which then makes a datatable pr date (details for the date) and i am putting this in the

void LocalReport_SubreportProcessing(object sender, Microsoft.Reporting.WinForms.SubreportProcessingEventArgs e)
        {
            var datoer = (from myrows in this.apoLogidose2DoseStudio.DS_Arbeidsplan.AsEnumerable()
                          select myrows.Dato).Distinct();
            DateTime datoSubReport = DateTime.Now;
            int tellenr = 0;
            foreach (var dato in datoer)
            {
                if (tellenr == subReportNr)
                {
                    datoSubReport = dato.Date;
                    break;
                }
                tellenr++;
            }
            var ArbeidsPlanRader = from myrows in this.apoLogidose2DoseStudio.DS_Arbeidsplan.AsEnumerable()
                                   where myrows.Dato.Equals(datoSubReport)
                                   select myrows;

            var a = new _002_Dataset.ApoLogidose2DoseStudio.DS_ArbeidsplanDataTable();
            foreach (var rad in ArbeidsPlanRader)
                a.ImportRow(rad);
            var dt = dtPrDag_(a,datoSubReport);

            e.DataSources.Add(new ReportDataSource("dsRptArbeidsplan",dt as DataTable));
            LocalReport re = sender as LocalReport;

            subReportNr++;
        }

the thing is that all the subreports gets the data from the first firing of subreportproccessing. IE when my logic is serving data from range dates 1 to 15 in a month i have checked the datatable dt that it contains the right data, IE increment the detail date from 1 to 15. But in all subreports it shows data from first date.

I cannot understand this so i have made a fix by making 10 copies of the subreport in the designer. But this limits the max number of dates to 10, i would like this to be completly dynamic, sometimes it is 1 date, sometimes it is 100.
