Use the MenuItemStyleCollection.RemoveAt(int) method to remove the System.Web.UI.WebControls.MenuItemStyle object at the specified zero-based index location from the collection. All items that follow that node are then moved up to fill the vacant position. The indexes of the moved items are also updated.

As an alternative, you can remove a specific System.Web.UI.WebControls.MenuItemStyle object by using the MenuItemStyleCollection.Remove(MenuItemStyle) method.
