multiple-series-types combine with Rangebar and LineSeries

[Sivakumar]

I am working on multiple-series-types-with-chartseriesprovider-and-typepath , I am using RangeBarSeries and lineseries Type. i am getting compile error as below.Please advice the right approach to add mixed series.

Additional information: Unable to cast object of type 'Telerik.Windows.Controls.ChartView.RangeBarSeries' to type 'Telerik.Windows.Controls.ChartView.CategoricalSeries'.

Hello Sivakumar,

The error appears because the CategoricalSeriesDescriptor doesn't support RangeSeries. Instead, you can use the base ChartCategoricalDescriptor.

<telerik:ChartSeriesDescriptor ItemsSourcePath="MyDataPointsCollection">
    <telerik:ChartSeriesDescriptor.Style>
        <Style TargetType="telerik:RangeSeries">
            <Setter Property="CategoryBinding" Value="MyCategory"/>
            <Setter Property="HighBinding" Value="MyHighValue"/>
            <Setter Property="LowBinding" Value="MyLowValue"/>
        </Style>
    </telerik:ChartSeriesDescriptor.Style>
</telerik:ChartSeriesDescriptor>

You can use this descriptor for all chart series.
