左键单击下带有上下文菜单的WPF按钮

我对ContextMenu有点小问题

<Window.Resources>
    <Style x:Key="ButtonWithContextMenuStyle" TargetType="Button">
        <Setter Property="Background" Value="#cbeb00" />
        <Setter Property="Foreground" Value="#505050" />
        <Setter Property="FontSize" Value="12" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border CornerRadius="4" Background="{TemplateBinding Background}"
                            BorderThickness="0">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" Margin="{TemplateBinding Padding}" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="#aaaaaa"/>
                            <Setter Property="Foreground" Value="#dcff00"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="ContextMenu">
            <Setter.Value>
                <ContextMenu>
                    <MenuItem Command="{Binding EditUserCommand}" Header="{DynamicResource EditUserContextMenuMW}"/>
                    <MenuItem Command="{Binding OpenHistoryCommand}" Header="{DynamicResource ConversationHistoryContextMenuMW}"/>
                    <MenuItem Command="{Binding OpenHistoryCommand}" Header="{DynamicResource BuyCreditContextMenuMW}"/>
                    <Separator />
                    <MenuItem Command="{Binding LogoutCommand}" Header="{DynamicResource LogoutContextMenuMW}"/>
                </ContextMenu>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <EventTrigger RoutedEvent="Click" >
                <EventTrigger.Actions>
                    <BeginStoryboard>
                        <Storyboard>
                            <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="ContextMenu.IsOpen">
                                <DiscreteBooleanKeyFrame KeyTime="0:0:0" Value="True"/>
                            </BooleanAnimationUsingKeyFrames>
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger.Actions>
            </EventTrigger>
        </Style.Triggers>
    </Style>
</Window.Resources>

当我点击鼠标右键时，一切正常。ContextMenu打开，我可以在MenuItem上调用命令

我希望在单击鼠标左键时看到相同的行为。但是，只有ContextMenu打开，我无法调用该命令

有人能告诉我我做错了什么吗？

您需要使用

鼠标右键向下

路由事件

<EventTrigger RoutedEvent="MouseRightButtonDown">

现在它应该可以工作了

以下是弹出窗口的命令：

  Command="{Binding CommandShowPopup}" CommandParameter="{Binding ElementName=btnMenuPopup}"

命令执行：

public class CommandShowPopup : ICommand
{
    public bool CanExecute(object parameter)
    {
        return true;
    }

    public event EventHandler CanExecuteChanged;

    public void Execute(object parameter)
    {
        (parameter as Popup).IsOpen = true;
    }
}

此解决方案为我提供了鼠标右键事件，即使我使用“MouseLeftButtonDown”，它也无法正常工作。两种解决方案都可以完美地处理事件，我在发布“stack”之前尝试了这一点，但我无法调用命令。我不知道为什么，因为在这个窗口中，我使用了命令，所有操作都正常（当然，除了这个）。问题是关联菜单与其放置目标不在同一个视觉树中：

    <Popup x:Name="btnMenuPopup" Placement="Mouse" StaysOpen="False">
        <Border BorderBrush="Black" BorderThickness="2" CornerRadius="2">
            <Menu>
                <MenuItem Header="Menu item 1" Command="{Binding EditCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"/>
                <MenuItem Header="Menu item 2" />
                <Separator />
                <MenuItem Header="Menu item 3" />
                <Menu.ItemsPanel>
                    <ItemsPanelTemplate>
                        <VirtualizingStackPanel Orientation="Vertical"/>
                    </ItemsPanelTemplate>
                </Menu.ItemsPanel>
            </Menu>
        </Border>
    </Popup>

 private void Button_Click(object sender, RoutedEventArgs e)
 {
   btnMenuPopup.IsOpen = true;
 }

  Command="{Binding CommandShowPopup}" CommandParameter="{Binding ElementName=btnMenuPopup}"

public class CommandShowPopup : ICommand
{
    public bool CanExecute(object parameter)
    {
        return true;
    }

    public event EventHandler CanExecuteChanged;

    public void Execute(object parameter)
    {
        (parameter as Popup).IsOpen = true;
    }
}
