ItemTemplate

The RadLegend control exposes an ItemTemplate property which you can use to change the default ItemTemplate. The DataContext of the template is a LegendItem object.

Note that a GeometryCloneConverter is used in the Path.Data Binding. This is to work around a limitation in the Silverlight framework, where an exception is thrown when a static resource is used to set the Data property of a Path.

A simple demonstration how to use the ItemTemplate property is given below:

<telerik:RadLegend HorizontalAlignment="Center" UseLayoutRounding="True"> 
    <telerik:RadLegend.ItemTemplate> 
        <DataTemplate> 
            <Border Background="{Binding MarkerFill}" BorderThickness="1" BorderBrush="{Binding MarkerStroke}"> 
                <Grid> 
                    <TextBlock Text="{Binding Title}" Foreground="White" Margin="15 0 0 0" /> 
                    <Path Width="12"  
                          Height="12"  
                          Fill="White"  
                          HorizontalAlignment="Left"> 
                        <Path.Data> 
                            <Binding Path="ActualMarkerGeometry" 
                                 RelativeSource="{RelativeSource AncestorType=telerik:LegendItemControl}"> 
                                <Binding.Converter> 
                                    <telerik:GeometryCloneConverter /> 
                                </Binding.Converter> 
                            </Binding> 
                        </Path.Data> 
                    </Path> 
                </Grid> 
            </Border> 
        </DataTemplate> 
    </telerik:RadLegend.ItemTemplate> 
    <telerik:RadLegend.Items> 
        <telerik:LegendItemCollection> 
            <telerik:LegendItem MarkerFill="#FF55AA33" MarkerStroke="Black" Title="Legend item 1" /> 
            <telerik:LegendItem MarkerFill="#FFCC3399" MarkerStroke="Black" Title="Legend item 2" /> 
            <telerik:LegendItem MarkerFill="#FF5511BB" MarkerStroke="Black" Title="Legend item 3" /> 
        </telerik:LegendItemCollection> 
    </telerik:RadLegend.Items> 
</telerik:RadLegend> 

And here is the end result:
