Force show tree lines for all the TreeListBoxItem's even when hiding the root item

Grids for WPF Forum

I have a TreeListBox in where the IsRootItemVisible="False" because I do not need it and also HasTreeLines="True". For the children of the root Item I would like to force show the tree lines for them. Currently those tree lines are not shown.

Can I somehow do that ?

Kind regards,

Hi Daniel,

Sorry, but tree lines are only supported when the child nodes are nested below a visible parent node.  Since the root node is being hidden, the children do not have an anchor from which the tree lines can be drawn.
