Remarks
By default, if the node expand buttons are displayed in the first column, the tree list control does not draw horizontal gridlines for the tree indents, as shown in the figure below.
If the node expand buttons are displayed in any other column, these gridlines are drawn for the entire width of the column by default.
Use the ShowHierarchyIndentationLines property to explicitly specify whether to draw these gridlines. In the figure below, the gridlines are drawn in the first column for the entire column width.
To specify the column that displays the node expand buttons, use the TreeList.HierarchyColumn or TreeList.HierarchyFieldName property.
