How to set Edge color ?

Jun 2, 2012 at 8:29 PM


I need to give each edge a weight and i have to set each edge color depends on it's weight .

I think the best way would be by setting the style of the EdgeControl , but i'm making something wrong . plz help !

Or at least if there is a way to do it by code ..

Like graphLayout.HighLightEdge(myEdge);

but it's not working for me !


Any help will be appreciated

If your custom edge has an int Weight property you could use the EdgeControl style to set the edge Foreground by binding to the Weight and using a converter to convert it into a color.


<Setter Property="Foreground" Value="{Binding Path=Weight, Converter={StaticResource MyConverter}}"/>


And then in MyConverter's Convert method:


        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
            int weight = value as int;
            if(weight < 10) return new SolidColorBrush(Colors.Blue);
            else if(weight<50) return new SolidColorBrush(Colors.Yellow);
            else if(weight<100) return new SolidColorBrush(Colors.Red);
            // or whatever other colors need to be returned
