这是我的菜单:

<Menu Name="menuInterfaces" ItemsSource="{Binding MenuItems}" Margin="0,8,0,0" Style="{StaticResource StandardMenu}">
    <Menu.ItemTemplate>
        <HierarchicalDataTemplate DataType="{x:Type Menu:MenuItemViewModel}" ItemsSource="{Binding Path=MenuItems}">
            <Grid>
                <TextBlock Text="{Binding Description}"/>
            </Grid>
        </HierarchicalDataTemplate>
    </Menu.ItemTemplate>
</Menu>

还有我的 Style :

<Style TargetType="{x:Type Menu}" x:Key="StandardMenu">
        <Style.Resources>
            <Style x:Key="{x:Static MenuItem.SeparatorStyleKey}" TargetType="Separator">
                <Setter Property="Height" Value="1"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="Separator">
                            <Border BorderBrush="{StaticResource MenuSeparatorBorderBrush}" BorderThickness="1" Margin="25,0,0,0"/>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
            <Style TargetType="{x:Type MenuItem}">
                <Setter Property="Foreground" Value="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType={x:Type Menu}}}"/>

视图模型:

public class MenuItemViewModel : INotifyPropertyChanged
    {
        private readonly ICommand _command;
        public event PropertyChangedEventHandler PropertyChanged;

        public string Name { get; set; }
        public string Description { get; set; }
        public string Id { get; set; }
        public bool _isSelected { get; set; }

        public MenuItemViewModel()
        {
            _command = new CommandViewModel(Execute);
        }

        public bool IsSelected
        {
            get { return _isSelected; }
            set
            {
                _isSelected = value;
                OnPropertyChanged("IsSelected");
            }
        }

        protected void OnPropertyChanged(string name)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
        }

        public ObservableCollection<MenuItemViewModel> MenuItems { get; set; }

        public ICommand Command
        {
            get { return _command; }
        }

        private void Execute()
        {
            // (NOTE: In a view model, you normally should not use 
        }
    }

现在我要做的就是添加 ToolTip 所以低于 Menu 我的分区 XAML 我添加了这个部分:

<Menu.ToolTip>
    <ToolTip>
         <StackPanel Orientation="Vertical">
               <TextBlock Text="{Binding Description}"/>
               <TextBlock Text="{Binding Name}"/>
               <TextBlock Text="{Binding Id}"/>
         </StackPanel>
     </ToolTip>
</Menu.ToolTip>

但是什么都没有显示所以我的怀疑是我的 风格 但我不知道在哪里……

有什么建议吗?

<Style TargetType="{x:Type MenuItem}">
    <Setter Property="ToolTip">
        <Setter.Value>
            <ToolTip>
                <StackPanel Orientation="Vertical">
                    <TextBlock Text="{Binding Description}"/>
                    <TextBlock Text="{Binding Name}"/>
                    <TextBlock Text="{Binding Id}"/>
                </StackPanel>
            </ToolTip>
        </Setter.Value>
    </Setter>

    <!-- etc -->
