void DisableMyChildMenus()
{
   
   // Determine if menuItem2 is a parent menu.
   if ( menuItem2->IsParent)
   {
      
      // Loop through all the submenus.
      for ( int i = 0; i < menuItem2->MenuItems->Count; i++ )
      {
         
         // Disable all of the submenus of menuItem2.
         menuItem2->MenuItems[ i ]->Enabled = false;

      }
   }
}

public void DisableMyChildMenus ()
{
   // Determine if menuItem2 is a parent menu.
   if (menuItem2.IsParent)
   {
      // Loop through all the submenus.
      for(int i = 0; i < menuItem2.MenuItems.Count; i++)
      {
         // Disable all of the submenus of menuItem2.
         menuItem2.MenuItems[i].Enabled = false;
      }
   }

Public Sub DisableMyChildMenus()
    ' Determine if menuItem2 is a parent menu.
    If menuItem2.IsParent = True Then
        ' Loop through all the submenus.
        Dim i As Integer
        For i = 0 To menuItem2.MenuItems.Count - 1
            ' Disable all of the submenus of menuItem2.
            menuItem2.MenuItems(i).Enabled = False
        Next i
    End If
End Sub
