如何使用 C# 从外部按钮单击查看Winrt应用程序中的特定设置页面？

在javascript中我发现这样 WinJS.UI.SettingsFlyout.showSettings("About", "/Settings/About.html")

但我无法在 c# 中找到它，我正在使用callisto设置 Flyouts

我也在使用 Callisto 和 C#，这就是我解决问题的方法。

    void OnCommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
    {
        var settings = new SettingsCommand("settings", "Settings", new UICommandInvokedHandler(showSettings));
        args.Request.ApplicationCommands.Add(settings);
        var credits = new SettingsCommand("credits", "Credits", new UICommandInvokedHandler(showCredits));
        args.Request.ApplicationCommands.Add(credits);
    }

    public void showSettings(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new SettingsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Settings";
        settings.IsOpen = true;
    }

    public void showCredits(IUICommand command)
    {
        var settings = new SettingsFlyout();
        settings.Content = new CreditsUserControl();
        settings.HeaderBrush = new SolidColorBrush(_background);
        settings.Background = new SolidColorBrush(_background);
        settings.HeaderText = "Credits";
        settings.IsOpen = true;
    }

然后从其他页面我可以打电话

((App)Application.Current).showCredits(null);

或者

((App)Application.Current).showSettings(null);

要调出我想查看的设置窗格 :o)

第一步是在您希望显示设置的页面的 SettingsPane 上为 CommandsRequest 事件添加一个侦听器。例如：

SettingsPane.GetForCurrentView().CommandsRequested += MainPage_CommandsRequested;

然后定义事件处理程序

void MainPage_CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
{
    SettingsCommand generalCommand = new SettingsCommand("GeneralSettings", ResourceLoader.GetString("GeneralText"), (x) =>
    {
        SettingsFlyout settings = new SettingsFlyout();
        settings.HeaderBrush = Resources["SettingsHeaderBrush"] as SolidColorBrush;
        settings.HeaderText = ResourceLoader.GetString("GeneralText");
        settings.Background = new SolidColorBrush(Windows.UI.Colors.White);
        settings.Content = new GeneralSettingsFlyout();
        settings.IsOpen = true;
        settings.Height = Window.Current.Bounds.Height;

        // Optionally, add a closed event handler
        settings.Closed += settings_Closed;
    });
}

请注意，在这种情况下，GeneralSettingsFlyout 只是一个页面，一旦选择了该特定设置，它将被加载到设置窗格中（Callisto 会自动处理这个）。

SettingsFlyout 是 Callisto 的类。

编辑您的 app.xaml 文件并为您的代码引用此代码段：

App::OnLaunched()
{
.
.
     var rootFrame = new CharmFrame { CharmContent = new CharmFlyouts() };
     SuspensionManager.RegisterFrame(rootFrame, "AppFrame");
.
.
}

然后，当您要显示该设置时，请执行以下操作：

SomeOtherMethod()
{
     ((Window.Current.Content as CharmFrame).CharmContent as CharmFlyouts).ShowSettings();
}
