Hi,

You cannot set the number of segments if AutoRoute is enabled, so you might have to set AutoRoute = false before the SegmentCount assignment. This also depends on the Style - Bezier links have 3 * SegmentCount + 1 control points. Additionally, the SegmentCount setter automatically sets the number of points, so you must not add new points to the collection. E.g. for polyline and cascading links, you can set the point coordinates like this

link.SegmentCount = (short) (arrayOfPoints.Length - 1);
for (int i = 0; i < arrayOfPoint.Length; ++i)
   link.ControlPoints[i] = arrayOfPoint[i];

I hope that helps,
Stoyan
