我一直在弄清楚如何将下拉列表绑定到我的绑定列表框。我想显示一个列表，其中包含下拉列表中显示的所有乘客及其座位号。管理员应该能够通过下拉列表更改乘客的座位号。

我曾尝试查看嵌套绑定，但找不到任何提及我的问题的内容。

XAML

<Page
    x:Class="FlightApplication.Passengers"

    <ListBox x:Name="ListBox1" Margin="5" Width="450" Height="200" HorizontalAlignment="Left" ItemsSource="{x:Bind PassengersList}" FontFamily="Segoe UI">
        <ListBox.ItemTemplate>
            <DataTemplate x:Name="PassengerLineTemplate" x:DataType="fdata:Passenger">
                <StackPanel Orientation="Vertical" Margin="2">

                        <Run Text="{x:Bind FirstName}"/>
                    </TextBlock>
                    <TextBlock>

                        <Run Text=" - "/>
                        <Run Text="{x:Bind SeatNr}"/>
                    </TextBlock>
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
        </ListBox>
</Page>

namespace FlightApplication
{
    public sealed partial class Passengers : Page
    {
        public ObservableCollection<Passenger> PassengersList = new ObservableCollection<Passenger>();
        public Passengers()
        {
            this.InitializeComponent();
            //ListBox1.DataContext = PassengersList; Do i use this?


        }
    }
}
