TcxGridChartSeries.OnValueClick Event

Occurs when a data marker is clicked.

Declaration

property OnValueClick: TcxGridChartValueClickEvent read; write;

Remarks

This event is fired when a drill-down is performed. Note that this event is fired even when:

• the drill-down functionality is disabled via the View’s OptionsCustomize.DataDrillDown property;

• a drill-down cannot be performed (the View’s Controller.IsDataDrillDownPossible function returns False).

The Sender and ASeries parameters identify the Chart View and the series whose value is clicked, respectively.

The AValueIndex corresponds to the index of the chart value being clicked in the VisibleValues collection of ASeries.

Set the AHandled parameter to True to cancel a drill-down operation. In this instance the View’s OnValueClick event for this series won’t be fired.
