Using NetAdvantage 2010 volume 2.
I want to display the list of selected nodes in the same order that they appear in the tree instead of the selected order which is the default behaviour.
The description of the function "SortByPosition" of the SelectedNodes collection is "Sorts the SelectedNodes collection such that members appear in the same order that they do in the tree."
So I would expect the nodes in the collection to be sorted in the same way that they appear in the tree from top-down but that does not seem to be the case.
In the following example, I would have expect the nodes to be sorted this way :
"Node0, Node6, Node8, Node10, Node3"
But the result is far different and I cannot figure the resulting sorting that is applied.
Is this a bug, or did I misunderstood the behaviour of that function?
Thanks
Sylvain
Hi,
I have created the following case for you: CAS-62698-9W9W9X. I have logged this behavior in our internal tracking system with a Development ID of 70351. If you have any other questions, do not hesitate to let us know through your case ot here in the forum.

Hi Sylvain,
SortByPosition is supposed to sort the nodes in the order in which they appear on the tree. If they are coming out in the order you show in the screen shot here, then something is clearly wrong.
I suspect the issue is that the SortByPosition method was added long before the tree had the ability to allow selection across different nodes collections. To test this out, I tried selecting nodes in the same collection, like Node3, Node2, and Node0. When I do this, it works fine.
So I consider this a bug and I'm going to ask Infragistics Developer Support to write this up for developer review.
Hello Sylvain,
Unfortunatelly the function "SortByPosition" have a different behavior and may be can not solve your issue. By default, the nodes in the UltraTree.SelectedNodes collection are in the order in which they were added to the collection. This generally means they are in the order in which they were UltraTreeNode.Selected. Calling the SortByPosition method will sort the TreeNodes so that they are in the same order as they appear in the UltraTree.
I made small exapmle for you with recursive method which do the same that you expect. Please look the example and send me a feedback. If you have any questions, do not hesitate to ask me
