RadPieChart DoughnutSeries selection does not work

[Stevo]

Hi Guys,

we are showing a simple doughnut series chart and would like to implement drilldown after user selects a part

<telerik:RadPieChart>
            <telerik:RadPieChart.Series>
            <telerik:DoughnutSeries  ShowLabels="False" ItemsSource="{Binding Items}" ValueBinding="Value">

                <telerik:DoughnutSeries.LabelDefinitions>
                        <telerik:ChartSeriesLabelDefinition Binding="Name"/>
                    </telerik:DoughnutSeries.LabelDefinitions>

                    <telerik:DoughnutSeries.LegendSettings>
                        <telerik:DataPointLegendSettings TitleBinding="Name" />
                </telerik:DoughnutSeries.LegendSettings>

                </telerik:DoughnutSeries>
            </telerik:RadPieChart.Series>

            <telerik:RadPieChart.Behaviors>
                <telerik:ChartSelectionBehavior DataPointSelectionMode="Single"
                                                SelectionChanged="ChartSelectionBehavior_SelectionChanged"   />
            </telerik:RadPieChart.Behaviors>
        </telerik:RadPieChart>

The ChartSelectionBehavior_SelectionChanged is never fired.

Note that this works fine with PieSeries, but does not work with DoughnutSeries

Any ideas?

Hello Stevo,

The issue you observed was fixed last week. Selection will work properly in the next official release, scheduled for the end of February. Until then you can manually set the IsHitTestVisible property of the series to true.
