adressing Detailsection of subreport

[Mark]

Hello

Im having trouble reaching the detailsection of a loaded subreport, in my mainreport contructor.

 

here is my subreport loading procedure:

 

   this.subLP5.ReportSource = new subLP5a();

//change pagebreak of subreport detailsection

     DetailSection ds = (DetailSection)this.subLP5.Report.Items["detaillp5a"];
     ds.PageBreak = PageBreak.None;

 

I get ds=null despite "detaillp5a" is the existing name for subLP5a detailsection.

Should I adress the detailarea in another manner?

 

regards

Mark

Hello Mark,

If you need to modify a report before displaying, the recommended approach is:

1. Get an instance of the master report;
2. Find the SubReport item;
3. Extract an instance of the sub report from the SubReport item;
4. Find the sub report's Detail section and modify it;
5. Set again the SubReport item's ReportSource to the modified sub report instance;
6. Display the master report;

For example:

InvoiceReport report = new InvoiceReport();



    //get the SubReport item
    var subReportItem = (Telerik.Reporting.SubReport)report.Items.Find("SubReport1", true)(0);

    //can be any type of report source
    var subReportItemReportSource = DirectCats(subReportItem.ReportSource, TypeReportSource);
    var typeName = typeReportSource.TypeName;
    var reportType = Type.GetType(typeName);
    //get the sub report instance
    var subReportInstance = (Report)Activator.CreateInstance(reportType);

    //update the sub report
    (subReportInstance.Items.Find("detail",true)[0] as Telerik.Reporting.DetailSection).PageBreak=.....;

    //set the updated sub report back to the SubReport item's ReportSource
    InstanceReportSource subIRS = new InstanceReportSource();
    subIRS.ReportDocument = subReportInstance;
    subReportItem.ReportSource = subIRS;

    //wrap the final report in a report source
    InstanceReportSource IRS = new InstanceReportSource();
    IRS.ReportDocument = report;

I hope this information is helpful.
