Remarks
By default, in the column that displays the node expand buttons, the tree list displays the nearest (leftmost in left-to-right oriented layouts) vertical gridlines, as in the figure below.
Set the ShowFirstLines property to false to hide these gridlines.
To specify the column that displays the node expand buttons, use the TreeList.HierarchyColumn or TreeList.HierarchyFieldName property.
