Question

我正在使用Controls:Tiles开发一个菜单栏，其属性为ContextMenu，只允许我点击鼠标右键打开它。经过一些搜索后，我用鼠标左键点击它，但行为不同：当我按下右键单击ContextMenu时，所有MenuItems都可以点击。当我按左键单击ContextMenu打开但所有MenuItems看起来已禁用，我无法点击它们。

我的代码在这里：

<Controls:Tile x:Name="FileTile" Width="Auto" Height="30" TitleFontSize="10" HorizontalContentAlignment="Left" 
                                       VerticalAlignment="Top" VerticalContentAlignment="Top" Background="White" HorizontalTitleAlignment="Right"
                                       Foreground="Gray" ContextMenuService.IsEnabled="True">
                    <Controls:Tile.Content>
                        <StackPanel Orientation="Horizontal" Height="Auto">
                            <Image Source="/images/topbaricons/files.png" Width="22" Height="22" VerticalAlignment="Center" HorizontalAlignment="Left"/>
                            <TextBlock Text="{x:Static p:Resources.File}" VerticalAlignment="Center" Margin="5,0,5,0" />
                        </StackPanel>
                    </Controls:Tile.Content>
                    <Controls:Tile.Style>
                        <Style TargetType="{x:Type Button}">
                            <Style.Triggers>
                                <EventTrigger RoutedEvent="Click">
                                    <EventTrigger.Actions>
                                        <BeginStoryboard>
                                            <Storyboard>
                                                <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="ContextMenu.IsOpen" FillBehavior="HoldEnd">
                                                    <DiscreteBooleanKeyFrame KeyTime="0:0:0" Value="True"/>
                                                </BooleanAnimationUsingKeyFrames>
                                            </Storyboard>
                                        </BeginStoryboard>
                                    </EventTrigger.Actions>
                                </EventTrigger>
                            </Style.Triggers>
                        </Style>
                    </Controls:Tile.Style>
                    <Controls:Tile.ContextMenu>
                        <ContextMenu x:Name="File_ContextMenu" >
                            <MenuItem Header="{x:Static p:Resources.Menu_item_New}" Command="ApplicationCommands.New" IsEnabled="true">
                                <MenuItem.Icon>
                                    <Image Source="/images/topbaricons/new_file.png" Height="22" Width="22" />
                                </MenuItem.Icon>
                            </MenuItem>
                            <MenuItem Header="{x:Static p:Resources.Menu_item_Open}" Command="ApplicationCommands.Open" IsEnabled="true">
                                <MenuItem.Icon>
                                    <Image Source="/images/topbaricons/open_file.png" Height="22" Width="22" />
                                </MenuItem.Icon>
                            </MenuItem>
                            <MenuItem Header="{x:Static p:Resources.Menu_item_Save}" x:Name="MenuItemSave" Command="ApplicationCommands.Save" IsEnabled="False">
                                <MenuItem.Icon>
                                    <Image Source="/images/topbaricons/save.png" Height="22" Width="22" />
                                </MenuItem.Icon>
                            </MenuItem>
                            <MenuItem Command="ApplicationCommands.SaveAs" Visibility="Visible" >
                                <MenuItem.Icon>
                                    <Image Source="/images/topbaricons/save_as.png" Height="22" Width="22" />
                                </MenuItem.Icon>
                            </MenuItem>
                            <MenuItem Header="{x:Static p:Resources.Menu_item_Exit}" Command="ApplicationCommands.Close" IsEnabled="true">
                                <MenuItem.Icon>
                                    <Image Source="/images/topbaricons/off.png" Height="22" Width="22" />
                                </MenuItem.Icon>
                            </MenuItem>
                        </ContextMenu>
                    </Controls:Tile.ContextMenu>
                </Controls:Tile>

为了准确显示我在这篇文章中所讨论的差异，有这个图像：

有人能帮助我吗？我真的想左键单击我可以做的右键单击。

感谢。

我认为命令的Pid将在某处处理（也许当前关注的元素具有自己的实现）。粘贴

link/1

和

CanExecute

应该这样做。

左侧的WPF ContextMenu仅显示但不要让我点击
