Hi,

I have created anchor points corresponding to radio buttons in my custom CompositeNode. There is a link emanating from each anchor point. Now I have an issue when arranging the chart using TreeLayout and its Anchoring value is set to Keep. For many nodes the order of child nodes in the tree does not correspond to the order of anchor points in the parent, and this makes the links all tangled up. Is there any way to make TreeLayout respect the order of my anchor points?
 
Thanks,

Thanks for the hint - connections will be drawn by our users in no definite order, so I ended up sorting them before arranging the tree. Hopefully this will be useful to somebody:

class SortByOAP : IComparer
{
     public int Compare(object x, object y)
     {
           DiagramLink l1 = (DiagramLink)x;
           DiagramLink l2 = (DiagramLink)y;
           return l1.OriginAnchor.CompareTo(l2.OriginAnchor);
     }
}

void OnTreeLayout(object sender, EventArgs e)
{
     foreach (DiagramNode n in diagram.Nodes)
     {
           ArrayList l = new ArrayList(n.OutgoingLinks);
           l.Sort(new SortByOAP());
           n.OutgoingLinks.Clear();
           foreach (DiagramLink dl in l)
                 n.OutgoingLinks.Add(dl);
     }
     TreeLayout tl = new TreeLayout();
     tl.Type = TreeLayoutType.Centered;
     tl.Direction = TreeLayoutDirections.LeftToRight;
     tl.LinkStyle = TreeLayoutLinkType.Rounded;
     tl.Anchoring = Anchoring.Keep;
     tl.Arrange(diagram);
}

It would be great to have this as a built-in sort option in TreeLayout May I also suggest you guys add methods to implement some common operations on the Diagram, for example SelectAll, InvertSelection, AlignSelection. They weren't too hard to code myself, but it should make a nice impression to your future evaluators
