Hello Praveen,

You could access the Brush of the Appointment's Category using the CategoryBrush property. Please, check the attached sample project that demonstrates how that could be achieved.

Hopes this helps.

Hi Team,

     <telerik:RadPieChart.Series>
                    <telerik:DoughnutSeries AngleRange="180,180"  >
                        <telerik:DoughnutSeries.DataPoints >
                            <telerik:PieDataPoint  Value="43.46"  Label=""/>
                                      </telerik:DoughnutSeries.DataPoints>
                    </telerik:DoughnutSeries>
                   </telerik:RadPieChart.Series>
               </telerik:RadPieChart>

Hi srivatshan,

You can change the color of the selected area of the DoughnutSeries by specifying the following style as the DefaultSliceStyle:

<telerik:DoughnutSeries.DefaultSliceStyle>
    <Style TargetType="Path">
        <Setter Property="Fill" Value="Blue" />
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsSelected}" Value="True">
                <Setter Property="Fill" Value="Yellow"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</telerik:DoughnutSeries.DefaultSliceStyle>

For your convenience, I've prepared a small sample project demonstrating this approach.

Please have a look and let me know whether this would work for you.

Hi Dilyan,

  <telerik:RadPieChart Grid.Column="1" Grid.Row="0" >
                <telerik:RadPieChart.Series>
                    <telerik:DoughnutSeries AngleRange="180,180" SelectedPointOffset="0"  ItemsSource="{Binding SelectedItems}" ValueBinding="nsv"   ShowLabels="True">
                        <telerik:PieSeries.LabelDefinitions>
                            <telerik:ChartSeriesLabelDefinition Margin="50,0,0,0" >

                                <telerik:ChartSeriesLabelDefinition.Template>
                                    <DataTemplate>
                                        <TextBlock Text="5" VerticalAlignment="Bottom" FontWeight="Bold" FontSize="20"/>
                                    </DataTemplate>

Hello sri,

As accessing the first label of the series will not be that straightforward, I can suggest simply defining a TextBlock below the chart, bound to the value of the first data point, like so:

<StackPanel>
    <telerik:RadPieChart Grid.Column="1" Grid.Row="0" >
        <telerik:RadPieChart.Series>
            <telerik:DoughnutSeries AngleRange="180,180" SelectedPointOffset="0"  ItemsSource="{Binding SelectedItems}" ValueBinding="nsv" ShowLabels="False">
                <telerik:DoughnutSeries.SliceStyles>
                    <Style TargetType="Path">
                        <Setter Property="Fill" Value="YellowGreen"/>
                    </Style>
                    <Style TargetType="Path">
                        <Setter Property="Fill" Value="Gray"/>
                    </Style>
                </telerik:DoughnutSeries.SliceStyles>
            </telerik:DoughnutSeries>
        </telerik:RadPieChart.Series>
    </telerik:RadPieChart>
    <TextBlock Margin="0 -50 0 0" Text="{Binding SelectedItems[0].nsv}" HorizontalAlignment="Center" />
</StackPanel>

Please note, however, that you may be able to achieve the same result by using the RadGauge control instead.

Could you please have a look at the documentation of the radial gauge control, check the available demos in our WPF Controls Samples application as well as in the SDK Samples Browser and let me know if it would work for you?

I'm looking forward to your reply.
