Question

我在启动时有一个窗口，您可以从2个组合框中选择一个接口和端口。单击“完成”后，它将转到主窗口，您可以在其中看到另外两个相同的COMbox。它们具有您在弹出窗口中选择的选定值。我可以在后面的代码中执行此操作吗？

这是我的弹出窗口winResetInterface.xaml：

Window x:Class="simpliphy.winResetInterface"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="winResetInterface" Height="280" Width="259">
<Grid Margin="0,-1,2,1">
    <ComboBox Name="cmbInterface" ItemsSource="{Binding Interface}" DisplayMemberPath="Name" HorizontalAlignment="Left" Margin="94,52,0,0" VerticalAlignment="Top" Width="91"/>
    <Button x:Name="btnFinishSetup" Click="btnFinishSetup_Click" Content="Done" HorizontalAlignment="Left" Margin="76,173,0,0" VerticalAlignment="Top" Width="75"/>
   <ComboBox x:Name="cmbPort"  ItemsSource="{Binding SelectedItem.Port, ElementName=cmbInterface}" HorizontalAlignment="Left" Margin="94,88,0,0" VerticalAlignment="Top" Width="91"/>
</Grid>

在我的代码背后：

     namespace project
    {

        public partial class winResetInterface : Window
        {
            public ObservableCollection<Model.Device_Class> Interface { get; set; }

                public winResetInterface()
                {
                   InitializeComponent();
                   DataContext = this;
                   Interface = new ObservableCollection<Model.Device_Class>();
                   Interface.Add(new Device_Class() { Name = "XGBE", Port = new ObservableCollection<string>() { "0" } });
                   Interface.Add(new Device_Class() { Name = "SATA0", Port = new ObservableCollection<string>() { "0", "1", "2", "3" } });
                 }
          }

        private void btnFinishSetup_Click(object sender, RoutedEventArgs e)
        {
            MainWindow main = new MainWindow();
            App.Current.MainWindow = main;
            this.Close();
            main.Show();

            //Set the selected options on the device stats sidebar
            ///THIS IS WHERE I'M STUCK!
            main.cmbInterface_main.SelectedItem = cmbInterface.SelectedItem;


        }
    }

在我的MainWindow中，我有一个组合框，其填充方式与box1，cmbInterface相同。我可以不只是将2个选定项目设置为彼此相等吗？

你可以这样做：

main.cmbInterface_main.SelectedIndex = cmbInterface_main.FindStringExact(cmbInterface.Text, 0);

虽然循环代码的评论是一个更好的答案。

WPF将combox的选定值发送到另一个窗口的相同组合框
