Question

我使用页面和NavigationWindow：

navigationWindow = new NavigationWindow();
            navigationWindow.Height = 200;
            navigationWindow.Width = 100;
            navigationWindow.WindowState = WindowState.Maximized;
            page = new IntroPage();
            navigationWindow.Navigate(page);
            navigationWindow.Show();

我使用GoBack和GoForward方法进行导航，但我不想通过快捷方式（鼠标中的功能按钮等）使用它们。如何禁用这些快捷方式？

在导航窗口XAML中，您可以添加：

<NavigationWindow.InputBindings>
    <KeyBinding Key="Back" Command="NotACommand" />
    <KeyBinding Key="Next" Command="NotACommand" />
    <KeyBinding Key="BrowserBack" Command="NotACommand" />
    <KeyBinding Key="BrowserForward" Command="NotACommand" />
    <KeyBinding Key="Left" Modifiers="Alt" Command="NotACommand" />
    <KeyBinding Key="Right" Modifiers="Alt" Command="NotACommand" />
</NavigationWindow.InputBindings>

在代码中你可以这样做：

navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.Back, ModifierKeys.None));
navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.Next, ModifierKeys.None));
navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.BrowserBack, ModifierKeys.None));
navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.BrowserForward, ModifierKeys.None));
navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.Left, ModifierKeys.Alt));
navigationWindow.InputBindings.Add(new KeyBinding(ApplicationCommands.NotACommand, Key.Right, ModifierKeys.Alt));

还可以阻止其他键，例如BrowserHome和BrowserRefresh。

如果正在显示导航UI，则会阻止热键，而不是鼠标导航。如果您只想以编程方式控制导航，则应在XAML中隐藏导航用户界面ShowsNavigationUI="False"（作为NavigationWindow标记的参数）或在代码中隐藏mainWindow.ShowsNavigationUI = false;。

此外，您可以像上面对KeyBindings一样阻止MouseBindings，添加具有MouseAction属性集的新MouseBinding对象。
