Answer 1

That format doesn't work for me. I'm forced to use:

// People often exclude the applicable "using" statements--so samples don't work!
using System.Web.UI.WebControls; 

// Create the MAIN menu item
MenuItem mnuMenuItem = new MenuItem();         

// Create the SUB menu item
MenuItem mnuSubMenuItem = new MenuItem();      

// Create the SUB menu item, "under" the MAIN menu item!
mnuMenuItem.ChildItems.Add(mnuSubMenuItem);
