insert node in treelist at specific position

[lugan2]

Dear all
I am trying to insert a node into a TreeListMenu. It can successfully add nodes into a tree, at different level - using parent and child relationship. The function I am using is:
[pre]this->tree_control0->InsertNode(CurrentNOde, ParentNode, NULL, Tree::NodeInsertOptionAlwaysFirst);[/pre]

However, the order of the nodes within the same level goes as the default order, no matter how I insert them. For example, if I would like to list a tree as (L0=level 0, L1=level 1):
_L0: a
___L1: b
___L1: c
_L0: d

where 'a' and 'b' are parent nodes, but 'b' and 'c' are child nodes of node 'a'. The problem is, no matter I insert 'b' first or 'c' first, it will always be displayed as 'c' listed after 'b'. This seems to follow apathetic order. (if I change the name of 'b' to be 'm' for example, the list will automatically updated as 'm' after 'c' in Level 1(L1).


Could anyone suggest a method that I may list the tree nodes in the way the user wanted but rather than default? I tried to change the option 'NodeInsertOptionAlwaysFirst' as other options, it doesn't help.

Many thanks

While inserting a column the default is 'ColumnSortOptionAscending'. After inserting the column set 'columnsortoption' to 'unsorted'.
