OnBeforeChangeControlValue (Control: Prognoz.Platform.Interop.Report.IPrxControl; Var Cancel: Boolean)
Control. Regular report control that generated event.
Cancel. The parameter that determines whether the event is fired. The property is set to False by default.
The OnBeforeChangeControlValue method implements the event that occurs before the value of a regular report control is changed.
On calling the method, the IPrxReportUserEvents.EventOnBeforeChangeControlValue event that can be redefined, if required, is processed in parallel.
The property use is given in the example for IPrxReportUserEvents.EventOnBeforeChangeControlValue.
