The following properties accept/return ChartSeriesPointSelectionMode values:

• DxChartBarSeriesBase<T, TArgument, TValue>.SelectionMode
• DxChartBubbleSeries<T, TArgument, TValue, TSize>.SelectionMode
• DxChartFinancialSeriesBase<T, TArgument, TValue>.SelectionMode
• DxChartRangeBarSeries<T, TArgument, TValue>.SelectionMode
• DxChartScatterSeries<T, TArgument, TValue>.SelectionMode
• DxChartSeriesPoint.SelectionMode
• DxPolarChartBarSeries<T, TArgument, TValue>.SelectionMode

Remarks

Specify the DxChart.PointSelectionMode property to enable point selection at the chart level.

You can also specify the DxChart.SeriesSelectionMode property to allow users to select entire series.

Note

For discrete series (for example, bars), the DxChart.PointSelectionMode property has a higher priority over the DxChart.SeriesSelectionMode property. This means that these properties are not applied simultaneously.

Example

The following example enables selection for a line chart:

• A user can select multiple points. Points with the same argument are selected when the user selects a point.
• A user can select an entire series by clicking a line segment. When the user selects a series, the selection of the previously selected series is reset.
