如何在Windows 8样式应用程序中将对象从框架传递到另一个框架 [英] How to pass an object from a Frame to another Frame in a Windows 8 Style App

问题描述

我有一个问题，我现在无法解决.我正在尝试开发Windows-8风格的应用程序，并且无法实现此功能.

I have problem that i just cant figure out right now. I am trying to develop a Windows-8 style app and im stuck implementing this functionality.

我有一个 MainWindow ，其中包含一个ListBox和一个Button(让我们说 addButton ).

I have a MainWindow which contains a ListBox and a Button (lets say addButton).

当我单击按钮导航到新页面时，使用this.Frame.Navigate(typeof(addCustomerPage));说 AddCustomerPage ；

When i click the button i navigate to a new page, lets say AddCustomerPage with this.Frame.Navigate(typeof (AddCustomerPage));

AddCustomerPage 有1个文本框和1个按钮(让我们说 doneButton .当我单击该按钮时，我希望将文本框中的字符串添加到上一个列表框中.页面.

AddCustomerPage has 1 textBox and 1 button (lets say doneButton. When i click the button i want the string in the textBox to be added to the ListBox on the previous page.

这是我当前的功能:1.创建MainWindow.

This is my current functionality: 1. MainWindow is created.

1. 单击addButton

1. Click addButton

AddCustomer页面已创建.MainWindow被破坏(问题).

AddCustomer page is created. MainWindow is destroyed(problem).

点击完成按钮

使用包含1个项目的ListBox创建MainWindow对象.

A MainWindow object is created with a ListBox with 1 item.

重复添加过程，我总是得到一个带有1个项目的ListBox的MainWindow.

Repeat the add process, i always get a MainWindow with a ListBox with 1 item.

感谢您的帮助.这是代码:

Thanks for the help. Here is the code:

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();

        this.brainPageController = new PageController();

        // add items from the List<String> to the listBox
        listGoals.ItemsSource = brainPageController.GetListGoals();
    }

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        var parameter = e.Parameter as String;
        // a simple controller that adds a string to a List<string>
        brainPageController.AddGoal(parameter);
    }

    private void addButton_Click(object sender, RoutedEventArgs e)
    {
        this.Frame.Navigate(typeof (GoalsInfo));
    }

    // VARIABLES DECLARATION
    private PageController brainPageController;
}

public sealed partial class GoalsInfo : WinGoalsWIP.Common.LayoutAwarePage
{
    public GoalsInfo()
    {
        this.InitializeComponent();
        this.brainPageController = new PageController();
    }

    protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)
    {
    }
    protected override void SaveState(Dictionary<String, Object> pageState)
    {
    }

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        brainPageController.AddGoal(nameTextBox.Text);

        this.Frame.Navigate(typeof(MainPage), nameTextBox.Text);
    }
    // VARIABLES DECLARATION
    PageController brainPageController;
}
