    Hello Sivakumar,

    The error appears because the CategoricalSeriesDescriptor doesn't support RangeSeries. Instead, you can use the base ChartCategoricalDescriptor.
    <telerik:ChartSeriesDescriptor ItemsSourcePath="MyDataPointsCollection">
            <Style TargetType="telerik:RangeSeries">
                <Setter Property="CategoryBinding" Value="MyCategory"/>
                <Setter Property="HighBinding" Value="MyHighValue"/>
                <Setter Property="LowBinding" Value="MyLowValue"/>                                   
    You can use this descriptor for all chart series.

    Do you need help with upgrading your AJAX, WPF or WinForms project? Check the Telerik API Analyzer and share your thoughts.
