TcxGridChartSeries.OnValueClick Event

Occurs when a data marker is clicked.

Declaration

property OnValueClick: TcxGridChartValueClickEvent read; write;

Remarks

The OnValueClick event also occurs when:

• Drill-down functionality is disabled through the View’s OptionsCustomize.DataDrillDown property.
• A drill-down operation is not available (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 does not occur.
