If I create a splitted/segmented arrow with the following code and try to select and move the arrow I get "Index out of range for PointCollection" collection.
Following is the code:

Arrow ar=flowchart.CreateArrow(startbox, -1,endbox, -1);
ar.ControlPoints.RemoveAt(0);
ar.ControlPoints.RemoveAt(0);
for(int i=0i<mycol.count;i++)
{
ar.ControlPoints.Add(mycol[i]);
}
ar.UpdateFromPoints();

mycol is collection of PointF objects that are saved previously from the same arrow.ControlPoints before deleting the arrow. I am try to recreate the arrow with the same split points. I know the reason is with SegmentCount not update properly. Can anyone advise me the proper way to recreate a split arrow so that when I move the arrow I do not get the exception messages like above.
