Highlighting Support

While selecting a leaf node, you can highlight it by setting HighlightOnSelection property of SfTreeMap to “True”. The border of highlight on selection can be customized by HighlightBorderBrush and HighlightBorderThickness properties of SfTreeMap.

Code Sample:

xaml

<syncfusion:SfTreeMap ItemsSource="{Binding PopulationDetails}"

                      WeightValuePath="Population" ColorValuePath="Growth"

                      HighlightOnSelection="True" 

                      HighlightBorderBrush="Yellow" 

                      HighlightBorderThickness="5">

    <syncfusion:SfTreeMap.Levels>

        <syncfusion:TreeMapFlatLevel GroupPath="Continent" GroupGap="10"/>

    </syncfusion:SfTreeMap.Levels>

</syncfusion:SfTreeMap>
