Embed Subreports

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 8 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.

Caution: It is recommended that you do not create a new instance of the subreport in the Format event. Doing so creates a new subreport each time the section Format code is run, using a lot of memory.

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.
