Hello, Actipro developers. When I use TreeListBox to dynamically load data, I find that when I set IsSelected in ViewModel to true, the selected highlight style does not take effect.
After my inspection, my ViewModel is correct before it is passed to the control, but when the control accepts ViewModel to create a "TreeNode" object (you seem to use "TreeNode" as an intermediate layer, my guess), the "IsSelected" of the returned "TreeNode" is false, which seems to notify my ViewModel data back, causing the failure of setting IsSelected to true.
I don't know if my inference is correct, here I give my simplest case to support you in checking this issue.
