Hide AllActiveReports allows you to use scripting to permit reports saved to an XML file to contain code. By including scripting when reports are saved into XML, the reports later can be loaded, run, and displayed directly to the viewer control without needing to use the designer.
This walkthrough illustrates how to use scripting when creating a subreport.
This walkthrough is split up into the following activities:
- Temporarily connecting the main report to a data source
- Connecting the subreport to a data source
- Adding controls to each report to display data
- Adding the scripting code for rptMain
- Viewing the report
 |
Tip: For basic steps like adding a report to a Visual Studio project and viewing a report, please see the Basic Data Bound Reports walkthrough. |
 |
Note: This walkthrough uses the Northwind database. By default, in ActiveReports, the Northwind.mdb file is located at [User Documents folder]\ComponentOne Samples\ActiveReports 9\Data\NWIND.mdb. |
When you have finished this walkthrough, you will have a report that looks similar to the following at design time and at runtime.
Design Time Layout (main report)

Runtime Layout (main report)

To add an ActiveReport to the Visual Studio project
- Create a new Visual Studio project.
- From the Project menu, select Add New Item.
- In the Add New Item dialog that appears, select ActiveReports 9 Section Report (xml-based) and in the Name field, rename the file as rptMain.
- Click the Add button to open a new section report in the designer.
See Adding an ActiveReport to a Project for information on adding different report layouts.
To connect the report to a data source
|
Note: The following steps are just for convenience so that the fields list in the Report Explorer can be populated at design time. |
- In the Report Data Source dialog, on the OLE DB tab, next to Connection String, click the Build button.
- In the Data Link Properties window that appears, select Microsoft Jet 4.0 OLE DB Provider and click the Next button to move to the Connection tab.
- Click the ellipsis (...) button to browse to your database, for example the NWind.mdb sample database. Click Open once you have selected the appropriate database path.
- Click the Test Connection button to see if you have successfully connected to the database.
- Click OK to close the Data Link Properties window and return to the Report Data Source dialog. Notice that the Connection String field gets filled automatically.
- In the Query field on the OLE DB tab, enter the following SQL query.
SQL Query Copy CodeSELECT * FROM Orders INNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID ORDER BY CompanyName, OrderDate - Click OK to save the data source and return to the report design surface.
To add a report for the subreport
- From the Project menu, select Add New Item.
- In the Add New Item dialog that appears, select ActiveReports 9 Section Report (xml-based) and in the Name field, rename the file as rptSub.
- Click the Add button to open a new section report in the designer.
- Right-click the PageHeader or PageFooter section and select Delete. Subreports do not render these sections, so deleting them saves processing time.
- Click in the grey area below the report to select it, and in the Properties window, change the report's ShowParameterUI property to False. This prevents the subreport from requesting a parameter from the user.

- Click OK to save the data source and return to the report design surface.
To create a layout for the main report
- Right-click the design surface of rptMain and select Insert then Group Header/Footer to add group header and footer sections to the report.
- In the Properties Window, make the following changes to the group header.
Property Name Property Value Name ghCompanies BackColor LemonChiffon CanShrink True DataField CompanyName GroupKeepTogether All KeepTogether True - In the Report Explorer, expand the Fields node, then the Bound node. Drag the CompanyName field onto ghCompanies and in the Properties window, set the properties as follows.
Property Name Property Value Size 4, 0.2 in Location 0, 0 in Font Bold True Font Size 12 - Right-click the design surface of rptMain and select Insert then Group Header/Footer to add the second group header and footer sections to the report.
- In the Properties Window, make the following changes to the second group header.
