Hello Nirmal,

Setting the Foreground property of ChartLegend is applied only to the legend header and not to the items. In order to change the foreground of the legend items, you should extend the default legend item style. Here is how you can do this:
xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting" 
 
        <telerik:RadChart x:Name="RadChart1" > 
            <telerik:RadChart.Resources> 
                <ResourceDictionary> 
                    <ResourceDictionary.MergedDictionaries> 
                        <ResourceDictionary Source="/Telerik.Windows.Controls.Charting;component/Themes/Chart/OfficeBlack/Styles.xaml" /> 
                    </ResourceDictionary.MergedDictionaries> 
                </ResourceDictionary> 
                <Style x:Name="LegendItemStyle" BasedOn="{StaticResource Telerik.Windows.Controls.Charting.ChartLegendItem}" TargetType="chart:ChartLegendItem"
                    <Setter Property="Foreground" Value="Black"/> 
                </Style> 
            </telerik:RadChart.Resources> 
        </telerik:RadChart> 
 
RadChart1.DefaultView.ChartLegend.LegendItemStyle = this.LegendItemStyle;
