[Solved] How do i bind a legend in a datatemplate?

[Bill]

I have a datatemplate with a number of pie charts.  
I'd like to show a legend with each one of them.  
The samples show binding to a chart by name which is not available in the datatemplate.  
Do you have any suggestions for how to bind the legend?  


<DataTemplate x:Key="PieGraphTemplate1">

     <Grid HorizontalAlignment="Left" Width="400" Height="400">

         <Border>

             <TelerikChart:RadPieChart PaletteName="DefaultDark" Margin="10,0">

                     <TelerikChart:DoughnutSeries ItemsSource="{Binding Items}">

                         <TelerikChart:DoughnutSeries.ValueBinding>

                             <TelerikChart:PropertyNameDataPointBinding PropertyName="Value"/>

                         </TelerikChart:DoughnutSeries.ValueBinding>

                     <TelerikChart:DoughnutSeries.LegendTitleBinding >

                         <TelerikChart:PropertyNameDataPointBinding PropertyName="Name"/>

                     </TelerikChart:DoughnutSeries.LegendTitleBinding>

                 </TelerikChart:DoughnutSeries>

             </TelerikChart:RadPieChart>

         </Border>

         <TelerikPrimitives:RadLegendControl LegendProvider="{Binding ????}"  >

             <TelerikPrimitives:RadLegendControl.ItemsPanel>

                 <ItemsPanelTemplate>

                     <StackPanel Orientation="Vertical"/>

                 </ItemsPanelTemplate>

             </TelerikPrimitives:RadLegendControl.ItemsPanel>

             <TelerikPrimitives:RadLegendControl.ItemTemplate>

                 <DataTemplate>

                     <StackPanel Orientation="Horizontal">

                         <Ellipse Fill="{Binding Fill}" Stroke="{Binding Stroke}" StrokeThickness="1" Width="20" Height="20"/>

                         <TextBlock Text="{Binding Title}" Foreground="{Binding Fill}"  Margin="10" FontStyle="Italic" FontSize="22"/>

                     </StackPanel>

                 </DataTemplate>

                 </TelerikPrimitives:RadLegendControl.ItemTemplate>

         </TelerikPrimitives:RadLegendControl>

     </Grid>

 </DataTemplate>

Hello Bill,

Thank you for your interest.

In the current scenario I can see that both the LegendControl and the Chart are in the DataTemplate, so ElementName binding should work as expected. For your convenience, I have attached a project that demonstrates this scenario. Please, see the attached file.

I hope this helps. Let me know should you have any further questions.
