How do I change the color of a connector programmatically?

From within a menu handler I wish to change the color of all the connectors from a shape? ClassStyleSet seems to a protected class when I access it from a ShapeElement.

You can write an internal method to change the pen color based on your own criteria. e.g. You can create a parital class for AggregrationColor class (a language based on ClassDiagram) and provide an internal method.

public partial class AggregationConnector
{

internal void SetConnectorColor ( System.Drawing.KnownColor color)
{
StyleSet classStyleSet = base.StyleSet;
DslDiagrams::PenSettings linePen = new DslDiagrams::PenSettings();
linePen.Color = global::System.Drawing.Color.FromKnownColor(color);
classStyleSet.OverridePen(DslDiagrams::DiagramPens.ConnectionLineDecorator, linePen);
classStyleSet.OverridePen(DslDiagrams::DiagramPens.ConnectionLine, linePen);

}
}

In your menu handler, you can find the right connect and call the SetConnectorColor method. When the diagram is being repainted, it will display the color you specified.
