MenuItem.Depth Property
.NET Framework (current version)
Gets the level at which a menu item is displayed.
Assembly: System.Web (in System.Web.dll)
Use the Depth property to determine the depth of the menu item. The depth indicates the level at which a menu item is displayed and represents the number of levels of hierarchy between the current menu item and the root menu item. For example, a root menu item has a depth of 0. A submenu item of the root menu item has a depth of 1, and so on.
The following example demonstrates how to use the Depth property to determine the depth of a menu item.
