Win - Show a full member path in the Customization Form - for a TreeList

Hello Support,

I've been following your two tickets, the first one How to show a full member path in the LayoutControl's Customization Form to avoid similar captions for properties with the same last member, which works for DetailView and the second one How to show a full member path in the Customization Form - for list views? which solves this for a ListView. However I've not been able to find a solution which would work for a TreeList.

Here is my code sample:

C#
// one mistake - the event has to be OnActivated() for grid to work
//protected override void OnViewControlsCreated()

protected override void OnActivated()
{
    base.OnViewControlsCreated();

    if (View is DetailView detailView)
    {
    ((WinLayoutManager)detailView.LayoutManager).ItemCreated += CustomizationFormCaptionController_ItemCreated;
    }
    else if (View is ListView listView)
    {
        if (listView.Editor is GridListEditor gridListEditor)
        {
            defaultEnablePropertyPathToolTip = GridEditorColumnChooserController.EnablePropertyPathToolTip;
            GridEditorColumnChooserController.EnablePropertyPathToolTip = false;
            gridListEditor.CustomizeGridColumn += GridListEditor_CustomizeGridColumn;
        }
        else if (listView.Editor is TreeListEditor treeListEditor)
        {
            defaultEnablePropertyPathToolTip = TreeListEditorColumnChooserController.EnablePropertyPathToolTip;
            TreeListEditorColumnChooserController.EnablePropertyPathToolTip = false;
            // what to do here?
        }
    }
}

private void GridListEditor_CustomizeGridColumn(object sender, CustomizeGridColumnEventArgs e)
{
    e.GridColumn.CustomizationCaption = CaptionHelper.GetFullMemberCaption(View.ObjectTypeInfo, e.GridColumn.FieldName);
}

private void CustomizationFormCaptionController_ItemCreated(object sender, ItemCreatedEventArgs e)
{
    if (e.ViewItem is PropertyEditor)
    {
        e.Item.CustomizationFormText = CaptionHelper.GetFullMemberCaption(View.ObjectTypeInfo, ((PropertyEditor)e.ViewItem).MemberInfo.Name);
    }
}

Could you give me an advice on how to solve this scenario for a TreeList?

Thank you.
