示例1: ZoneSelectationViewModel
public ZoneSelectationViewModel(Device device)
{
Title = "Выбор зоны устройства " + device.PresentationAddressAndName;
CreateCommand = new RelayCommand(OnCreate);
EditCommand = new RelayCommand(OnEdit, CanEdit);
Device = device;
IsGuardDevice = (device.Driver.DeviceType == DeviceType.Sequrity);
Zones = new BindingList<ZoneViewModel>();
foreach (var zone in from zone in FiresecManager.Zones orderby zone.No select zone)
{
var isGuardZone = (zone.ZoneType == ZoneType.Guard);
if (isGuardZone ^ IsGuardDevice)
continue;
