Add parameters programmatically for printing report

[Inge]

I'm trying to set my parameters trough my WPF application and after print my report. The printing works but the parameters are empty.

var report = new Badge();

report.ReportParameters["VisitId"].Value = code;
report.ReportParameters["VisitorName"].Value = visitorName;
report.ReportParameters["CompanyName"].Value = companyName;
report.ReportParameters["RegularVisitor"].Value = regularVisitor ? "REGULAR" : "VISITOR";

PrinterSettings printerSettings = new PrinterSettings();
printerSettings.PrinterName = ConfigurationManager.AppSettings["PrinterNameLabel"]);

PrintController standardPrintController = new StandardPrintController();
ReportProcessor reportProcessor = new ReportProcessor();
reportProcessor.PrintController = standardPrintController;
TypeReportSource typeReportSource = new TypeReportSource();

typeReportSource.TypeName = report.GetType().AssemblyQualifiedName;

reportProcessor.PrintReport(typeReportSource, printerSettings);

 

As attached file my parameter settings. Any ideas? Thanks for the help

Hello Inge,

Once the type name of the report is passed to the TypeReportSource, a new instance of the Badge report will be created internally by the reporting engine.

Thus, you need to set the report parameters via the TypeReportSource object, and not via the report instance. This way they will be passed correctly to the report:

var typeReportSource = new Telerik.Reporting.TypeReportSource();

// Specifying the assembly qualified name of the Report class for the TypeName of the report source
typeReportSource.TypeName = typeof(Invoice).AssemblyQualifiedName;

// Adding the initial parameter values
typeReportSource.Parameters.Add(new Telerik.Reporting.Parameter("OrderNumber", "SO43659"));

Thanks for the help! This solution made it work.

Is it possible to do the same for a list of objects? For example insert this list into rows for a table: 

public static void PrintVisitList(List<Visit> visits)
        {
            try
            {
                //print en report objects
                PrinterSettings printerSettings = new PrinterSettings();
                PrintController standardPrintController = new StandardPrintController();
                ReportProcessor reportProcessor = new ReportProcessor();
                TypeReportSource typeReportSource = new TypeReportSource();

                //set printersettings
                printerSettings.PrinterName = ConfigurationManager.AppSettings["PrinterNameLabel"];
                reportProcessor.PrintController = standardPrintController;
                // Specifying the assembly qualified name of the Report class for the TypeName of the report source
                typeReportSource.TypeName = typeof(VisitList).AssemblyQualifiedName;

                //Adding data
                foreach (var visit in visits)
                {
                    VisitList.tblVisitorsRow row = ds.tblVisitors.NewtblVisitorsRow();
                    row.VisitorKey = visit.VisitId;
                    row.Arrival = visit.Arrival;
                    row.FirstName = visit.FirstName;
                    row.LastName = visit.LastName;
                    row.CompanyName = visit.CompanyName;
                    row.PhoneMobile = visit.PhoneMobile;
                    row.VehicleLicensePlate = visit.VehicleLicensePlate;
                    row.AppointmentWith = visit.AppointmentWith;

                    ds.tblVisitors.Rows.Add(row);
                }

                //print command
                reportProcessor.PrintReport(typeReportSource, printerSettings);
            }
            catch (Exception ex)
            {
                LogRepository.AddLog(new Log
                {
                    Data = ex.InnerException?.Message ?? ex.Message
                });
            }
        }

 

For example the foreach loop?

Hi Inge,

In your code snippet you are updating data at run-time. This will require you to modify the report before processing it and to use an InstanceReportSource instead of the TypeReportSource.

For example:

//create an instance of the report that can be modified
var reportInstance = new VisitList();
reportInstance.DataSource=ds.tblVisitors;
//or if data is visualized by a nested data item like a Table/List/Crosstab
//we use the Find method - http://docs.telerik.com/reporting/overload-telerik-reporting-reportitembase-itemcollection-find
//(reportInstance.Items.Find("table1",true) as Telerik.Reporting.Table).DataSource = ds.tblVisitors;

//use an InstanceReportSource to wrap the modified report instance
var IRS = new InstanceReportSource { ReportDocument = reportInstance};

Report parameters' values can be updated through the report instance's ReprotParameters collection or the InstanceReportSource.Parameters collection.

Thanks for the help but the find won't work for me. I fixed it this way:

//create an instance of the report that can be modified
                var reportInstance = new VisitList
                {
                    //add visitlist
                    table1 = {DataSource = visits}
                };

                //use an InstanceReportSource to wrap the modified report instance
                var instanceReportSource = new InstanceReportSource { ReportDocument = reportInstance };

 

Problem solved for me!
