use variables from winform in the CrystalReportViewer

in my win form i have two datetimepickers.

first user selects dates from those two controls to filter the data between 2 dates.

and then click a button to generate the report.

in the same form i have CrystalReportViewer control.

when the user clicks the button i can get the data and show it in the CrystalReportViewer.

what i can't do is add a title to report header using those 2 dates selected by the user.

like this,
All Item In Inventory From 20/2/2010 To 28/2/2010

One way could be using a formula field...
Insert a new Formula Field, let's say MySubTitle
This formula's text could be "Trim('From dd/mmm/yyyy To dd/mmm/yyy')" or anything else
Now in your print code, before to view the report, place the next code

Code:

---

Dim CRCount as Integer
For CRCount = 0 To CRReport.DataDefinition.FormulaFields.Count - 1
  Select Case CRReport.DataDefinition.FormulaFields.Item(CRCount).Name.ToString
    Case "MySubTitle"
      CRReport.DataDefinition.FormulaFields.Item(CRCount).Text = "Trim(" & Chr(39) & "From:  " & Format(MyDate1, "dd/MMM/yyyy") & "  To:  " & Format(MyDate2, "dd/MMM/yyyy") & Chr(39) & ")"
    End Select
  Next CRCount

---

MyDate1 and MyDate2 come from the DatePickers
Chr(39) ---> single quote

thanks for replying. i have found a way to do it.

here is how.

i added a special filed (Report Title) to my report at design time.

then in my win form which contains the crystal report viewer i added this code

objRpt1.SummaryInfo.ReportTitle = "Item Issued Between " & DTP1.Value.Date & " and " & DTP2.Value.Date & "."

this works, but might not be the best way.

Thank you
I learn another way to do it
