How to create a master-detail report using a Subreport

The Master-Detail Report article in the XtraReports documentation describes how to create master-detail reports in two ways - via the DetailReportBand and XRSubreport controls. The first approach is preferable and can be easily used in XAF. However, if you need to use the second approach, steps required to implement it in XAF should be slightly modified, because generally the class on the Many side of an association does not have a simple property with the master's ID. You can filter a detail report by the master object's ID:

[C#]
usingDevExpress.ExpressApp.Reports;privatevoidsubreport1_BeforePrint(objectsender,System.Drawing.Printing.PrintEventArgse){XRSubreportsubreport=(XRSubreport)sender;subreport.ReportSource.Parameters["MasterID"].Value=((XafReport)xafReport1).ObjectSpace.GetKeyValue(GetCurrentRow());}

For additional information, please see reports in the attached example.

Note, this example is now included as a part of the FeatureCenter demo.

IMPORTANT NOTES
If you use the ViewDataSource (from the ReportsV2 module) for the master report, then you will have to modify your script as follows:

[C#]
usingDevExpress.Xpo;privatevoidsubreport2_BeforePrint(objectsender,System.Drawing.Printing.PrintEventArgse){XRSubreportsubreport=(XRSubreport)sender;subreport.ReportSource.Parameters["MasterID"].Value=((ViewRecord)GetCurrentRow())["Oid"];}
