The DevExpress ASP.NET Tree List (ASPxTreeList) provides multiple options that control the visibility of:

  • border;
  • tree lines;
  • grid lines.

In this demo, toggle the Show tree lines and Show control's border check boxes to show/hide the tree lines and border, respectively.

The ASPxTreeList provides multiple gridline styles. It can render horizontal or vertical lines only, or both horizontal and vertical lines. This is controlled by the Settings.GridLines property.

In this demo, use the 'Grid lines' combo box to select the required gridline style.
