How to change crystal report document title dynamically?
Thanks,
Alex.Hi Alex,
i am new member of this forum...

you can try the following:

ReportDocument oRpt = new ReportDocument ();
oRpt.SummaryInfo.ReportTitle = yourinputcontrol.Text;

as in my case it was a checklist box so i did as follows

Reports.TIPSheetsSummary frmTIPSummaryReport = new TIPSheetsSummary();
frmTIPSummaryReport.oRpt.SummaryInfo.ReportTitle = "TIP Sheets Summary for Airplane Tab No. " + this.checkedListBox1.SelectedItem.ToString();
