Setting the ZIndex for CartesianPlotBandAnnotation while using AnnotationsProvider

[Deepak]

I am using the following AnnotationsProvider to generate annotations using data bindings:

<code>
<telerik:RadCartesianChart.AnnotationsProvider>

                                            <telerik:ChartAnnotationsProvider Source="{Binding LocationHistory}">
                                                <telerik:ChartAnnotationDescriptor>
                                                    <telerik:ChartAnnotationDescriptor.Style>
                                                        <Style TargetType="telerik:CartesianPlotBandAnnotation">
                                                            <Setter Property="Axis" Value="{Binding HorizontalAxis, RelativeSource={RelativeSource AncestorType=telerik:RadCartesianChart}}" />
                                                            <Setter Property="From" Value="{Binding Item2}" />
                                                            <Setter Property="To" Value="{Binding Item3}" />
                                                            <Setter Property="Fill" Value="{Binding Item1, Converter={StaticResource LocationToBrushConverter}}" />
                                                        </Style>
                                                    </telerik:ChartAnnotationDescriptor.Style>
                                                </telerik:ChartAnnotationDescriptor>
                                            </telerik:ChartAnnotationsProvider>
                                        </telerik:RadCartesianChart.AnnotationsProvider>
</code>

I have a bunch of LineSeries elements as well inside the RadCartesianChart element which is the parent of this AnnotationsProvider.

I am trying to get these annotations to render below all the LineSeries elements. But I am unable to set the ZIndex propery through ChartAnnotationDescriptor.Style. Could you please let me know if there is a workaround for this issue?

Hello Deepak,

You can set the ZIndex property of the annotations like so:

<Setter Property="ZIndex" Value="-10" />

Or alternatively, you can set the Panel.ZIndex attached property.

<Setter Property="Panel.ZIndex" Value="-10" />
