ChartControl.SelectedItems Property

Gets the collection of selected items (chart points and series) and business data objects (in the case of using a data source) of the ChartControl object.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v22.1.UI.dll

NuGet Package: DevExpress.Win.Charts


public IList SelectedItems { get; }

Property Value

Type Description

A list which contains selected chart points, series and business data objects (in the case of using a data source).


Use the SelectedItems property to get the collection of chart points and series.


When the chart control is connected to a data source, the SelectedItems property returns a collection of business data objects (stored in the SeriesPoint.Tag property) instead of selected series points.


This example shows how to obtain currently selected series points and show them in another chart. To do this, the ChartControl.SelectedItemsChanged event should be used.

In this example, you can choose the selection behavior (Single, Multiple or Extended) from the Selection Mode combo box. When any country is selected in the pie chart, you can see the population dynamics for each country in the bar chart. To cancel pie segment selection, choose None in the Selection Mode combo box.

In addition, this example demonstrates how to colorize each bar series point in the pie specific color using the ChartControl.CustomDrawSeriesPoint event.
