hi Dipak.
u can use "Report Title" or "Report Comments" Or "File Author" Field in Special Fields Section of Crystal Report Designer and place them title section of your crystal report and set values of these fields in coding as shown example
Private Sub BtnOk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnOk.Click
Me.ViewReceiptTableAdapter.Connection = Connection
Me.ViewReceiptTableAdapter.FillByDate(Me.DSetFeeReports.ViewReceipt, Me.DtDate.Value)
CryDailyCollection1.SummaryInfo.ReportTitle = " Report Of " & ComboCity.text & "City"
CryDailyCollection1.SetDataSource(Me.DSetFeeReports)
Me.CrystalReportViewer1.ReportSource = CryDailyCollection1
End Sub
This is easiest way to set dynamic Title of any crystal report.
i hope this solve your problem
