I am doing similar thing as FlowCharter example.
I need help in two things:
1. I tried to use "delete" key on keyboard to delete a selected node. It works in the example, but doesn't work in mine. What I am missing? I tried the same thing as FlowChater for context menu delete, that works.

2. I tried to place nodes at certain coordinate on the diagram because I have comment box placed close to certain node, so I need ability to place node at exact location on diagram. I am reading those X, Y in from XML. I am trying to place on diagram by diagram.factory.createshapenode(point, size). This doesn't work. It only controls the bounds of the node. Which method controls the node location in the diagram?

Thanks,

Thank you, Stoyan!
1st one works!

2nd one, I tried things like:
double yloc =0;
for (var node in nodes)
{
yloc += 50;
Point pt = new Point(50, yloc);
var diagramnode = diagram.Factory.CreateShapeNode(pt, new Size(120, 40));
}

I thought the nodes should line up from top to bottom since y increases vertically, but what I got is a line from left to right horizontally. I switched x, y, I still got the same thing. For now, no link involved in. Any ideas what I did wrong?

Thank you, Stoyan!
Now I understand what you mean by "Check if something else doesn't move the nodes later". I used LayerLayout.arrange(diagram).

You cannot reuse FlowchartLayout link arrangement for other layout classes, since it relies too much on links' and nodes' correspondence to source code constructs.

If you need to arrange only links after nodes have been arranged, try calling:

diagram.RouteAllLinks();

or:

new OrthogonalRouter().Arrange(diagram);

I hope that helps,
Stoyan
