Grouping

Hierarchical Reporting

You may now use hierarchical grouping to arrange data in a report to show hierarchical relationships. You still keep all the elements of the hierarchy in the same table, but you can now display the relationships between the elements. This can be useful, for example, when reporting off a Human Resources database, to show the organizational hierarchy within a company.

In the Report Designer Component runtime, the following properties have been added to implement this grouping under the Area class:

You can use the InstanceIDField and ParentIDField properties to organize the group sorting tree, use the GroupIndent property to design the layout, and use the EnableHierarchicalGroupSorting property to enable or disable hierarchical group sorting.

At design time you may select hierarchical grouping for your report in the Report Designer Component, by right-clicking and choosing Report|Hierarchical Grouping Options. This will invoke the Change Hierarchical Options dialog box.

For more information and an example of how to use this feature, please refer to the Crystal Reports User's Guide.
