directedtreelayout

[Mary Fontana]

I am displaying nodes with directed tree layout.
I am allowing option to display the nodes top-to-bottom and left-to-right.


DirectedTreeLayout tree = new DirectedTreeLayout(diagramModel, diagramView);

//treeOrientation = TreeOrientation.TopBottom or
// TreeOrientation.LeftRight
diagramModel.Orientation = treeOrientation; //

tree.PrepareActivity(tree);
tree.StartNodeArrangement();
tree.RefreshLayout();

(diagramView.Page as DiagramPage).InvalidateMeasure();
(diagramView.Page as DiagramPage).InvalidateArrange();



When display top-to-bottom the top node is always at the middle of the diagramview. and the bottom nodes are always at the very bottom of bounds for the diagram view. I would like the top node to start at the top, but horizontal center.
Or if top node is not at very top, the entire tree centered in the view.

Similarly, when displaying from left to right I want the top node and bottom nodes to be centered horizontally in the view.

Thanks,
mary

Hi Mary,

With regards to displaying nodes with directed tree layout, Directed-Tree layout will position the nodes based on the layout root. The Bounds property of the Diagram View class enables to specify the rectangular area where the tree layout is to be displayed. The root of the tree layout is placed at the center of the bounds value.

For further details please refer the dashboard sample ,
