Re: [Microsofts_C_Sharp] problem with crystal report parameters

Hello Koen,
 
I see that you want to pass parameters to your report. Please try using the followign code snippet and check if it helps you:
=======================================================================
ParameterFields crParameterFields;
CrystalDecisions.CrystalReports.Engine. ParameterFieldDefinitions parmdef;
ParameterField crParameterField;
ParameterValues crParameterValues;
ParameterDiscreteValue crParameterDiscreteValue; 
 

crParameterFields = CrystalReportViewer1.ParameterFieldInfo;
crParameterField = crParameterFields["pfCustomer"];   
crParameterValues = crParameterField.CurrentValues;
crParameterDiscreteValue = new ParameterDiscreteValue();
crParameterDiscreteValue.Value = "parameter value";
crParameterValues.Add(crParameterDiscreteValue);   
CrystalReportViewer1.ParameterFieldInfo = crParameterFields;
=======================================================================
 
Let me know if this works.
 
 
Regards,
Venkat

Hello everybody,

I'm trying to create a crystal report from my C# code. I call it the
way that I saw in a tutorial, but it seems that the parameter is not
passed, although, when I look in debug mode, the parameter gets a
value. Could anybody help? I've got a parameterfield in the report
called: pfCustomer

Now the code I use to set the parameters to the report is the
following:

// new report document object
                  ReportDocument oReport = new ReportDocument
();

                  // loading the ItemReport in report document
                  oReport.Load (reportLocation);

                  // set the selected report as the source
                  crystalReportViewer1.ReportSource = oReport;

                  // all the parameter fields will be added to
this collection
                  ParameterFields paramFields = new
ParameterFields();

                  // the parameter fields to be sent to the
report
                  ParameterField pfCustomer = new ParameterField
();

                  // setting the name of parameter fields with
wich they will be recieved in report
                  pfCustomer.ParameterFieldName = "pfCustomer";

                  // the above declared parameter fields accept
values as discrete objects
                  // so declaring discrete objects
                  ParameterDiscreteValue dcCustomer = new
ParameterDiscreteValue();

                  // setting the values of the discrete objects
                  dcCustomer.Value = reportParameters
["Customer"];

                  // now adding these discrete values to
parameters
                  pfCustomer.CurrentValues.Add(dcCustomer);

                  // now adding all these parameter fields to
the parameter collection
                  paramFields.Add(pfCustomer);

                  // finally add the parameter collection to
the crystal report viewer
                  crystalReportViewer1.ParameterFieldInfo =
paramFields;

I hope anyone can help me!

Thanks in advance!
Koen
