Property Value

Type	Description
Object	The chart element that is currently selected or deselected.

Remarks

Use the e.ChangedElement property to get the series point whose selection state is changed. The e.IsSelected property returns this selection state. The following code calls a custom UpdateStatistics method for the last selected series point:

C#

private void chartOfCountriesArea_SelectionChanged(object sender, ChartElementSelectionChangedEventArgs e) {
    selectedItemsText.Text = String.Format("Total area of ​​selected countries: {0}", totalArea);
    if (e.IsSelected) {
        UpdateStatistics((CountryStatisticInfo)e.ChangedElement);
    }
}

VB.NET

Private Sub chartOfCountriesArea_SelectionChanged(ByVal sender As Object, ByVal e As ChartElementSelectionChangedEventArgs)
    selectedItemsText.Text = String.Format("Total area of ​​selected countries: {0}", totalArea)
    If e.IsSelected Then
        UpdateStatistics(CType(e.ChangedElement, CountryStatisticInfo))
    End If
End Sub
