QUESTION:
How do I get my Crystal Reports report to drill-down when using the cCrystal class?

ANSWER:
There are a list of properties for the ActiveX preview that have been defaulted. You can change these defaults using the following code in your report object:

Procedure OnDisplayReport Handle hoReport
    Handle hoViewer

    Get ActiveXReportViewerObject of hoReport to hoViewer

    Set ComEnableDrillDown of hoViewer to TRUE

    Set ComDisplayTabs of hoViewer to TRUE

    Set ComEnableCloseButton of hoViewer to TRUE

End_Procedure // OnDisplayReport


The Order Entry sample includes an example of the use of those properties in the ReportPreviewCR.rv report view.


This is a list of properties that are available:
        Set ComDisplayToolbar           of hoViewer To True

        Set ComDisplayBorder            of hoViewer To False

        Set ComDisplayTabs              of hoViewer To False

        Set ComDisplayBackgroundEdge    of hoViewer To True

        Set ComDisplayGroupTree         of hoViewer To False

        Set ComEnableGroupTree          of hoViewer To False

        Set ComEnableStopButton         of hoViewer To False

        Set ComEnablePrintButton        of hoViewer To True

        Set ComEnableCloseButton        of hoViewer To False

        Set ComEnableRefreshButton      of hoViewer To False

        Set ComEnableExportButton       of hoViewer To True

        Set ComEnableSearchExpertButton of hoViewer To True

        Set ComEnableHelpButton         of hoViewer To False

        Set ComEnableZoomControl        of hoViewer To True

        Set ComEnableSearchControl      of hoViewer To True

        Set ComEnableNavigationControls of hoViewer To True
