使ListView项目从FormItemSource选中

我有一个这样的ListView

 <ListView x:Name="lview" SelectionMode="Multiple">
        <ListView.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Name, Mode=OneWay}" />
            </DataTemplate>
        </ListView.ItemTemplate>
        </ListView>

我像这样将数据绑定到此Listview

        public MainPage()
    {
        this.InitializeComponent();
         ObservableCollection<OptionItem> io = new ObservableCollection<OptionItem>();
        io.Add(new OptionItem { Name = "11111111111", IsSelected=false });
        io.Add(new OptionItem { Name = "22222222222", IsSelected=true });
        io.Add(new OptionItem { Name = "33333333333", IsSelected=true });
        io.Add(new OptionItem { Name = "44444444444",IsSelected=false });

        lview.ItemsSource = io;
    }   

Now you can see inside my Model, I have a Property called IsSelected. How can I bind this to the listView, so that the Items selected int he ItemsSource comes as selected in ListView?
