I am dynamically creating tables and anchor points and linking arrows to output and input anchor points.  First I create all the tables and then I create the arrow by calling the createarrow method.  After each createarrow method call i call the rearrange function which uses the treelayout object's arrange method.  But some how the arrows are no longer pointing to the anchor points on the chart. All arrows are pointing to the center of the table instead.  This is the settings I use on the treeLayout object.

           treeLayout.Type = TreeLayoutType.Centered;
           treeLayout.ArrowStyle = TreeLayoutArrowType.Straight;
           treeLayout.Direction = TreeLayoutDirection.RightToLeft;
           treeLayout.ReversedArrows = false;
           treeLayout.LevelDistance = 10;
           treeLayout.NodeDistance = 10;
           treeLayout.XGap = 10;
           treeLayout.YGap = 30;
           //treeLayout.KeepRootPosition = false;
           treeLayout.Anchoring = Anchoring.Keep;
          //treeLayout.IgnoreArrowDirection = true;
           treeLayout.Root = Root;
           treeLayout.Arrange(AssessmentTree);

I follow the sample code in the Entities sample for the most part in creating anchor points.

          // set connection points
           ArrayList al = new ArrayList();
//t is the Mindfusion table control
           for (int i = 0; i < t.RowCount; i++)
           {
               al.Clear();
//B.block.InputList contains the collection of inputs.
//There could be several outputs
               if (i < B.block.InputsList.Count)
               {
                   t[0, i].PicturePos = ImageAlign.Center;
                   t[0, i].Picture = images.Images[0];
                   IOInfo input = B.block.InputsList[i] as IOInfo;
                   t[1, i].Text = input.Id.ToString();
                   AnchorPoint ptin = new AnchorPoint(50, 50, false, true, Color.Red, 0, input.Id);
                   ptin.MarkStyle = MarkStyle.None;
                   al.Add(ptin);
               }
//B.block.OutputList contains the collection of
//outputs. Usally there will be only one output.

               if (i < B.block.OutputsList.Count)
               {
                   t[3, i].PicturePos = ImageAlign.Center;
                   t[3, i].Picture = images.Images[1];
                   IOInfo output = B.block.OutputsList[i] as IOInfo;
                   t[2, i].Text = output.Id.ToString();
                   t[2, i].TextFormat.Alignment = StringAlignment.Far;
                   AnchorPoint ptout = new AnchorPoint(50, 50, true, false, Color.Red, 3, output.Id);
                   ptout.MarkStyle = MarkStyle.None;
                   al.Add(ptout);
               }

               t.Rows[i].AnchorPattern = new AnchorPattern(
               (AnchorPoint[])al.ToArray(typeof(AnchorPoint)));

Thanks. We create a large tree and this feature is necessary to have keep the tree ordered.
