TcxGridChartView.OnValueClick Event

Occurs when a data marker for a particular chart value is clicked.

Declaration

property OnValueClick: TcxGridChartValueClickEvent read; write;

Remarks

The OnValueClick event also occurs 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).

Event Parameters

The Sender parameter provides access to the Chart View that raised the OnValueClick event.

The ASeries parameter identifies the series whose value has been clicked.

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 the pending drill-down operation.

Note

The OnValueClick event of a series can override the View’s OnValueClick event since the series OnValueClick event occurs last.
