Hello

I have a report with 10 data fields, I would like users to run a report and give them the option to include the data fileds they desire by checking their title on a check box. How do I include the fields on a report based on which checkbox is checked?

Thanks,

Victor

There is no easy way to do that.

One way which leaves much whote space is to put all the fields on the report then using parameters suppress the ones not chosen.

Are all fields the same data type? For example all text ot numeric?

Yes the are all text, datasource is an XML file. How would you suppress the fields and how would it impact the spacing between the fields? Would they automatically rearrange?

No they would not rearrange.

If they are all text fields then you could use formulas for the report

How will you call the report?
Formulas can be changed from the application.

I'm using the following approach with VB.NET:

DonorXML1.RecordSelectionFormula = "{Donor.DonorName} like " & "'*" & TextBox1.Text & "*'" & ""
With DonorXML1
CrystalReportViewer1.ReportSource = DonorXML1
End With

Thanks,

V.

Is that the standalone or the version that comes with VS2008?

Try this idea

In the report create 10 formulas
They can simply be an empty string " "
Name the checkboxes as an array of checkboxes
Declare 2 integer variables
Index
FormulaIndex
Syntax for the application is approximate since I don't know .Net

In the application
DonorXML1.RecordSelectionFormula = "{Donor.DonorName} like " & "'*" & TextBox1.Text & "*'" & ""
FormulaIndex = 0
For Index = 0 to 9
    If CheckBox(Index) = CHCECKED then
          FormulaIndex  = FormulaIndex  + 1
          DonorXML1.Formulas(FormulaIndex 0.Text = CheckBox(Index).FieldName - Not Sure how you do this
    End if
With DonorXML1
CrystalReportViewer1.ReportSource = DonorXML1
End With

Hi,

Main problem is I need to rearrage the columns when I remove certain columns, is that at all possible in Crystal Reports?

Thanks for the code.

No.

However the code I provided uses the formulas from left to right assuming they are put on the report in that order.
