    Hi Telerik,
    I am tryint create PieChart. I could able to generate the chart,but have difficulty in customizing label.
    Please go throught the attached code.
    I don't want default % values to display as a label's. if you locate DataItem.MainCode,that is where i am trying to change lable data. I get empty label's on chart.

    <telerik:PieSeries x:Name="PieSeries1" ShowLabels="True"    RadiusFactor="0.7" AllowSelect="True" SelectedPointOffset="0.2" 
                           IsSelected="True"  ItemsSource="{Binding PendingCertificationSatusInfosColl}" IsHitTestVisible="True"
                           ValueBinding="PendingCount"  >         
            <!--<telerik:ChartSeriesLabelDefinition Margin="-5,0,0,0" DefaultVisualStyle="{StaticResource LabelStyle}" />-->
            <telerik:ChartSeriesLabelDefinition Margin="-15,0,0,0" DefaultVisualStyle="{StaticResource LabelStyle}" 
                            <TextBlock Text="{Binding DataItem.MainCode}" 
                                           Foreground="White" /> 
                            <TextBlock Text="{Binding DataItem.PendingCount}" 
                                           Foreground="White"  /> 
            <telerik:AngleRange StartAngle="270"
                                        SweepAngle="360" /> 
            <DropShadowEffect BlurRadius="5" ShadowDepth="0"  Direction="315" Color="White"/>

    Hi Rakesh,

    I created a small project based on your code snippet. I altered just a few things in order to compile and run the project. Everything seems ok, I see a properly displayed pie chart with labels. Check the attached image and project for a reference. Is it possible that the Background of your project is White? Both of the TextBlocks have White foreground, so this might be the reason you do not see the labels even though they are there. Let us know how it goes.

    Kind regards,
