Programmatically change selected edge color

Jan 20, 2012 at 3:27 PM

Hi all,

i found these method "graphLayout.HighlightEdge(Edge<object, object> edge, Object highlightInfo)" and "graphLayout.RemoveHighlightFromEdge(Edge<object, object> edge)"  to change selected edge color, and it works.

But the colors I want are different from Black and Silver that these methods produce. So i ask is possible to change these colors?

Or are there another functions to call or xaml to write to programmatically change the color of an edge?

Find it!

Probably it can be done by xaml code, but i don't know WPF very well; so i found a solution via c# code.

If for example e1 is the variable that contain edge to modify color, and Acqua is the color you want..:

EdgeControl ec1 = graphLayout.GetEdgeControl(e1);
Brush pp1 = new SolidColorBrush(Colors.Aqua);
ec1.Foreground = pp1;

You can also define different styles for EdgeControl in XAML as resources.

Then you just get an EdgeControl object for the targeted edge and change its Style property.
