WPF:如何在不禁用箭头键导航的情况下禁用选项卡导航？

public class CustomKeyboardNavigation : KeyboardNavigation
{
    protected override void OnGotKeyboardFocus(KeyboardFocusChangedEventArgs e)
    {
        base.OnGotKeyboardFocus(e);
        // 在这里添加自定义的逻辑，例如禁用选项卡导航
    }

    protected override void OnLostKeyboardFocus(KeyboardFocusChangedEventArgs e)
    {
        base.OnLostKeyboardFocus(e);
        // 在这里添加自定义的逻辑，例如恢复选项卡导航
    }
}

    xmlns:local="clr-namespace:YourNamespace">
   <Window.Resources>
       <local:CustomKeyboardNavigation x:Key="customKeyboardNavigation" />
    </Window.Resources>
    <Grid KeyboardNavigation.TabNavigation="Local">
       <Button Content="Button 1" TabIndex="1" />
       <Button Content="Button 2" TabIndex="2" KeyboardNavigation.TabNavigation="None" />
       <Button Content="Button 3" TabIndex="3" />
    </Grid>
</Window>

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        KeyboardNavigation.SetTabNavigation(button2, KeyboardNavigationMode.None);
    }
}
