Tree Layout and Reorgnaize nodes

Hi Stoyo

I am generating a orgnogram using "TreeLayout".
Now once the tree is generated, I am allowing user to re-position/resize the nodes.

For eq. allowing user to resize the nodes should re-arrange all downlevel nodes
Or
Re-positioning the node should re-arrange all nodes on same level and downlevel for all nodes.

I tried to re-arrange the nodes & links which are in downlevel but not working as expected.

-Regards
Rajesh

Hi Rajesh,

Changing the order of a node relatively to its siblings can be done by changing the index of the link that connects it to its parent in the parent's OutgoingLinks collection. E.g. if you want a node to become leftmost under its parent, remove the corresponding link from parent.OutgoingLinks and insert it at index 0.

I suppose you'll have to re-arrange the tree branch that starts from the parent node after that, by setting TreeLayout.Root and enabling KeepRootPosition.

Regards,
Stoyan
