Hi,

If you mean the order of child nodes in TreeLayout, this depends on the order of links from parent to child nodes in the parent' OutgoingLinks collection. So you could rearrange OutgoingLinks before applying TreeLayout and will get the child nodes in the same order as the links in that collection.

Stoyan

The last link that you create to connect a parent node to a child goes last in the parent's OutgoingLinks collection, and applying TreeLayout moves that last child to the right of the other children of that node. If you remove the link from OutgoingLinks and insert it again at a different position, applying the layout would result in moving the respective child node to the same position in the row of children.

I hope that helps,

The links coming out from a parent are placed in the same order they are in OutgoingLinks, and as consequence, their Destination nodes (the children) are in that order too. To change the order of sibling nodes, find their parent and set the positions of the siblings' incoming links inside the parent's OutgoingLinks list.

node.OutgoingLinks.Clear(), and then call node.OutgoingLinks.Add() for each link in the order you need them. That probably would require you to keep a copy of the outgoing links collection so you don't lose the link references.

I hope that helps,
Stoyan

There is the TreeLayout.Direction property, but left-to-right and right-to-left there define the order from parent to child node, and not the relative order of child nodes. So you might have to reverse the order of OutgoingLinks if what you need is reversing the order of children.

I hope that helps,

Hi,

Seems we broke this while implementing your 'assistant' nodes. We'll upload a fix tomorrow.

Hello,
I checked the new dlls you sent me, but my problem was not fixed. I want explain again what is my problem: I have a DiagramNode that its OutGoingLinks property contains 4 links. I want that the links will be ordered in the same order they are in the OutGoingLinks list, but they aren't: The OutGoingLinks list contains the following nodes in this order: Node A, Node B, Node C and Node D, but in the diagram, after I added the links and did TreeLayout.Arrange operation the nodes are displayed in the following order from left to right: Node C, Node D, Node A, Node B. Why it is so? Why the nodes are not displayed in the same order their links are ordered in the OutGoingLinks  list??? 
Thanks
