有一个转换器像如下，

public sealed class NullToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value == null ? Visibility.Hidden: Visibility.Visible;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

现在，随着能见度属性的属性绑定为好。就像，

Now, bind the property with the Visibility property as well. Like,

<ListBox ItemsSource="{Binding Path=Squad}" 
         Visibility="{Binding Converter={StaticResource nullToVisibilityConverter}, 
                              Path=Squad}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <CheckBox Content="{Binding}" />
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>
