TreeList_ShowTreeLines

By default, tree lines are displayed or hidden depending on the currently applied skin. Use the ShowTreeLines property to explicitly specify whether to display tree lines. If the this option is enabled, you can specify the style of node hierarchy lines using the TreeListOptionsView.TreeLineStyle property.

By default, node expand/collapse buttons are drawn on a background that detaches the buttons from the tree lines. You can hide this background by setting the CustomDrawNodeButtonEventArgs.AllowDrawBackground property to false in a TreeList.CustomDrawNodeButton event handler.
