如何在 Windows Phone 应用程序中保存复选框的值 [英] how to save the value of the checkbox in a windows phone application

问题描述

我正在尝试让我保持选中状态的复选框，即使我关闭应用程序或在页面之间移动也是如此.

I'm trying to get the Checkboxes that I have stay checked, even when I close the app or move from page to page.

有人可以帮我吗?

推荐答案

在 XAML 中一个快速的方法是:

An fast way would be this in XAML:

    <CheckBox x:Name="CheckBox1" Checked="CheckClick" Unchecked="UncheckClick" />

在代码后面:

    public MainPage()
    {
        InitializeComponent();
        Loaded += MainPage_Loaded;

    }

    void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        var settings = IsolatedStorageSettings.ApplicationSettings;
        if (settings.Contains("CheckBox1Checked"))
            CheckBox1.Checked = settings["CheckBox1Checked"];
    }

    private void OnChecked(object sender, RoutedEventArgs e)
    {
        var settings = IsolatedStorageSettings.ApplicationSettings;
        settings["CheckBox1Checked"] = true;
        settings.Save();
    }


    private void OnUnchecked(object sender, RoutedEventArgs e)
    {
        var settings = IsolatedStorageSettings.ApplicationSettings;
        settings["CheckBox1Checked"] = false;
        settings.Save();
    }

最好使用 MVVM 和像

Better would be using MVVM and binding like

    <CheckBox IsChecked="{Binding IsCheckbox1Checked" />
