Runtime Features
When you run this sample, the blank Viewer form appears, with the drop-down list of the sample reports on the top of the form. Select the report from the drop-down list to have it displayed in the Viewer control. You can select from the following options.
- Simple SubReport - the basic sample report that demonstrates how to embed a report into another report. See rptSimpleMain and rptSimpleSub for details.
- Nested SubReport - the report demonstrates how to nest subreports to display main, child, and grandchild levels in a report. See rptNestedParent, rptNestedChildMain and rptNestedChildSub for details.
- Hierarchical SubReport - the main report dataset with the SHAPE statement defines the hierarchical structure of the report that uses a subreport. See rptHierarchicalMain and rptHierarchicalSub for details.
- SubReport using the data set that contains relationship - the main report having dataset with the relation that is defined in code, in the DataSet.Relations property of the main rptDSRelationParent report. See rptDSRelationParent, rptDSRelationChildMain and rptDSRelationChildSub for details.
- Master-detail report containing a SubReport - the sample report that demonstrates how to create a master detail report that uses a subreport. See rptMasterMain and rptMasterSub for details.
- Bookmark in SubReport - the sample report that uses bookmarks from the subreport. See rptBookmarkMain and rptBookmarkSub for details.
- Use a parameter in the SubReport - the sample report demonstrates how to set up a parameter in the data source of the subreport. See rptParamMain and rptParamSub for details.
-
To view the Dataset with multiple tables using SubReports - the sample report with the dataset that contains multiple data tables. The main report uses subreports to output multiple tables in a single report. See rptUnboundDSMain and rptUnboundDSSub for details.
Note: To run this sample, you must have access to the Nwind.mdb. A copy is located at [User Documents folder]\GrapeCity Samples\ActiveReports 10\Data\NWIND.mdb. If you are unable to access the data files in the sample, create the Data folder and place all the data files to this folder, or change the reference path to the data files within the folder according to your environment.
