To embed a subreport into a parent report, you add two reports (one parent and one child report) to a Visual Studio project, and from the ActiveReports 12 Section Report toolbox, drag the SubReport control onto the parent report. The following steps take you through the process of adding a subreport in a section report.

These steps assume that you have already added a Section Report (code-based) template in a Visual Studio project. See Adding an ActiveReport to a Project for further information.

To add code to create an instance of the child report in the parent report

1. Double-click the gray area around the parent report to create an event-handling method for the ReportStart event.
2. Add code like the following to the handler to create a new instance of the child report.

   To write the code in Visual Basic

   Visual Basic.NET code. Paste JUST ABOVE the ReportStart event.	Copy Code
   Dim rpt As rptYourChildReportName

   Visual Basic.NET code. Paste INSIDE the ReportStart event.	Copy Code
   rpt = New rptYourChildReportName()

   To write the code in C#

   C# code. Paste JUST ABOVE the ReportStart event.	Copy Code
   private rptYourChildReportName rpt;

   C# code. Paste INSIDE the ReportStart event.	Copy Code
   rpt = new rptYourChildReportName();

To add code to display the child report in a subreport control on a parent report

1. Add the SubReport control onto the design surface of the parent report.
2. Double-click the detail section of the report to create a detail_Format event.
3. Add code like the following to the handler to display a report in the SubReport control.

   To write the code in Visual Basic

   Visual Basic.NET code. Paste INSIDE the Format event.	Copy Code
   Me.SubReport1.Report = rpt

   To write the code in C#

   C# code. Paste INSIDE the Format event.	Copy Code
   this.subReport1.Report = rpt;
