Do you have samples for container node?

Thanks a lot.

Is there a way to resize the ContainerNode by mouse? But I don't want to resize other ShapeNodes in the same diagram.

Can I drag and drop a ShapeNode from the NodeListView directly to a ContainerNode? In the project FlowCharter, I can only drag a ShapeNode to the diagram, then drag it to the ContainerNode.

Would you please give some code snippet?

Thanks a lot.

As for dragging from the listview to a ContainerNode, first set

containerNode.AllowDrop = true;

Next download this version - it adds raising NodeCreated for nodes dropped from the NodeListView:

and handle NodeCreated like this

DiagramNodeCollection nodes = diagram.GetNodesAt(e.Node.Bounds.Location);
foreach (DiagramNode node in nodes)
{
     ContainerNode containerNode = node as ContainerNode;
     if (containerNode != null)
     {
           containerNode.Add(e.Node);
           break;
     }
}

I hope that helps,

You want the new nodes to move further down the diagram when you expand the container? or they should simply appear above the container on the Z order?

If each node in your diagram is in a container, that should be simple. You could handle the ContainerFolded and Unfolded events and run any of the layout algorithms from there. Set the layout's MultipleGraphsPlacement property to Vertical to order the containers in column, and pass a DiagramItemCollection containing all ContainerNodes as an argument to the Arrange method.

I hope that helps,

You could add all top-level nodes to an array or list, and offset all nodes whose Bounds.Y value is greater than the (un)folded container 's Y when the Folded/Unfolded event is raised. By top-level nodes I mean ones that are not in a container. The amount to offset the nodes below the container should be equal to the difference between the container's Bounds before folding it and its CaptionHeight.

I hope that helps,

It seems what you need is something like a vertical stackpanel -like layout, which we haven't considered using ContainreNodes for until now. I suppose we could implement it as a simple layout class, say StackLayout, rather than as a feature of the ContainerNode class.

In the ContainerFolded event handler, the height in the ContainerBound equals to the CaptionHeight.
How can I get the expanded height of the ContainerNode? I think it should be save somewhere inside the ContainerNode.

Also, how can I get the horizontal offset between the folded ContainerNode and the expanded ContainerNode?

Thanks.
