Fore Example

Public Class EventsClass: Parent
    Public Sub OnBeforeExportReport(Report: IPrxReport; Var Cancel: Boolean);

    Begin
        //Call system event redetermined in the Parent class
        Inherited OnBeforeExportReport(Report, Cancel);

    End Sub OnBeforeExportReport;
        Public Sub OnAfterExportReport(Report: IPrxReport);
    Begin
        //Call system event redetermined in the Parent class
        Inherited OnAfterExportReport(Report);
    End Sub OnAfterExportReport;
End Class EventsClass;
Public Class Parent: ReportEvents
    //Redetermine the EventOnBeforeExportReport system event
    Public Sub EventOnBeforeExportReport(Args: IUiPrxExportCancelEventArgs);
    Begin
        //Handle system event
    End Sub EventOnBeforeExportReport;
    //Redetermine the EventOnAfterExportReport system event
    Public Sub EventOnAfterExportReport(Args: IUiPrxExportEventArgs);
    Begin
        //Handle system event
    End Sub EventOnAfterExportReport;
End Class Parent;

The EventsClass class is a regular report events handler. On exporting a report the EventOnBeforeExportReport redetermined system event is called, in which export parameters can be changed.

Fore.NET Example

Imports Prognoz.Platform.Interop.Report;

Public Class EventsClass: Parent
    Public Override Sub OnBeforeExportReport(Report: IPrxReport; Var Cancel: Boolean);

    Begin
        //Call system event redetermined in the Parent class
        Inherited OnBeforeExportReport(Report, Var Cancel);

    End Sub OnBeforeExportReport;
    Public Override Sub OnAfterExportReport(Report: IPrxReport);
    Begin
        //Call system event redetermined in the Parent class
        Inherited OnAfterExportReport(Report);
    End Sub OnAfterExportReport;
End Class;
Public Class Parent: PrxForeNetReportUserEventsClass
    //Redetermine the EventOnBeforeExportReport system event
    Public Override Sub EventOnBeforeExportReport(Args: UiPrxExportCancelEventArgs);
    Begin
        //Handle system event
    End Sub EventOnBeforeExportReport;
    //Redetermine the EventOnAfterExportReport system event
    Public Override Sub EventOnAfterExportReport(Args: UiPrxExportEventArgs);
    Begin
        //Handle system event
    End Sub EventOnAfterExportReport;
End Class Parent;
