如何在框架 c# WPF 中禁用导航快捷方式

问题描述

如何禁用框架中的导航快捷方式(例如，用于向后导航的Backspace"和用于向前导航的Alt+右箭头").

How can I disable the navigation shortcuts in a frame (for example the "Backspace" for navigation backward and "Alt+Right arrow" for navigation forward).

我想使用其他键盘功能，所以我想禁用框架的导航快捷键.

I want to use other keyboard functions, so I want to disable the navigation shortcuts of the frame.

谁能帮帮我?

推荐答案

有一个更优雅的解决方案，可以使用附加行为来禁用导航，而无需实际扩展框架.

there is a more elegant solution where Attached behaviours can be used to disable navigation without actually extending a frame.

创建附加行为:

using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;

namespace A
{
    public static class DisableNavigation
    {
        public static bool GetDisable(DependencyObject o)
        {
            return (bool)o.GetValue(DisableProperty);
        }
        public static void SetDisable(DependencyObject o, bool value)
        {
            o.SetValue(DisableProperty, value);
        }

        public static readonly DependencyProperty DisableProperty =
            DependencyProperty.RegisterAttached("Disable", typeof(bool), typeof(DisableNavigation),
                                                new PropertyMetadata(false, DisableChanged));



        public static void DisableChanged(object sender, DependencyPropertyChangedEventArgs e)
        {
            var frame = (Frame)sender;
                       frame.Navigated += DontNavigate;
            frame.NavigationUIVisibility = NavigationUIVisibility.Hidden;
        }

        public static void DontNavigate(object sender, NavigationEventArgs e)
        {
            ((Frame)sender).NavigationService.RemoveBackEntry();
        }
    }
}

并且在 xaml 中添加这个每当你使用一个框架:

And in the xaml add this whenever you use a frame :

<Frame beha:DisableNavigation.Disable="True" />

并在 xaml 顶部添加导入:

and at the top of the xaml add the import :

xmlns:beha="clr-namespace:A"
