How to create layout dynamicly (Web)

I created my boxes but they will not lay out like I would like.  I tried this code but id does not work.
     LayeredLayout ll = new LayeredLayout();
     ll.SplitLayers = true;
     ll.LayerDistance = 50;
     ll.NodeDistance = 60;
     ll.Orientation =
          MindFusion.WebChart.LayoutSystem.Orientation.Vertical;
     ll.Arrange(fc);

Any and all help would be greatly appreciated.

Thanks
Nick

Hi,

Doesn't that code move the nodes at all, or it moves them to wrong positions ?

Are all nodes in the same graph? If the diagram has several graphs, the nodes in each graph will be laid out using vertical layout, but the graphs themselves are just stringed in a single row.

Hi,

Please send me the diagram data too - use SaveToFile or XmlWriter and email me the saved diagram.

Thanks

Now that I centered all nodes(boxes) the arrows are not in the center and I can not figure how to change them.  I emailed you the JPG to show you what I mean.  Thanks

Hi,

Assign to all boxes an AnchorPattern object that allows one incoming arrow at position (50, 0) and one outgoing arrow at (50, 100). Then the arrows will always go out from / come into exactly the centers of node top and bottom sides.

Another possibility is to explicitly set the positions of arrow.ControlPoints[0] and arrow.ControlPoints[arrow.ControlPoints.Count - 1]. After doing that call arrow.UpdateFromPoints so the arrowhead direction is recalculated.

I hope that helps,
Stoyan

The following code is how I tried to implement your sugestion but it did not change anything.  What am I doing wrong?

public class ScheduleDisplay : System.Web.UI.Page
{    
     .
     .
     .
     private AnchorPattern ap = new AnchorPattern(new AnchorPoint[]{
new AnchorPoint(50, 0, true, false),
new AnchorPoint(50, 100, false, true)});
     .
     .
     .
     public void buildStartTerm(DataSet dsSchedule)
         {
.
.
.
Box boxStart = fc.CreateBox(0, 0, 100, 50);
boxStart.AnchorPattern = ap;
.
.
.
fc.FitDocToObjects(10);
         }

.
.
.
public void buildBox(DataSet dsSchedule, int i)
{
Box bx = fc.CreateBox(0,0,200,100);
bx.AnchorPattern = ap;
.
.
.
}

}

Try setting the layout's Anchoring property to 'Reassign'. The default value is 'Ignore', which makes the layout not use anchor points at all.
