wpf - WPF Telerik RadContextMenu および RadMenuItem:余分な強調表示された行を RadMenuItem から削除する方法

Question

RadMenuItem

RadMenuItem は、メニューを表示するために使用されます

 <Style TargetType="{x:Type telerik:RadMenuItem}">
    <Setter Property="HorizontalContentAlignment" Value="{Binding Path=HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
    <Setter Property="VerticalContentAlignment" Value="{Binding Path=VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
    <Setter Property="Background" Value="{StaticResource ContextMenuBackground}"/>
    <Setter Property="Foreground" Value="{StaticResource ContextMenuForeground}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type telerik:RadMenuItem}">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="*"/>
                        <RowDefinition />
                    </Grid.RowDefinitions>

                    <Border x:Name="Border"
                        Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding Background}"
                        BorderThickness="2"
                        CornerRadius="5">

                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto"
                                              MinWidth="17"
                                              SharedSizeGroup="Icon" />
                                <ColumnDefinition Width="Auto" MinWidth="5"
                                              SharedSizeGroup="Name" />
                                <ColumnDefinition MinWidth="5" Width="Auto" 
                                              SharedSizeGroup="Shortcut" />

                                <ColumnDefinition MinWidth="10" Width="Auto" 
                                              SharedSizeGroup="Arrow" />
                            </Grid.ColumnDefinitions>


                            <ContentPresenter x:Name="Icon"
                                          Margin="4,0,6,0"
                                          VerticalAlignment="Center"
                                          ContentSource="Icon" />

このコードは、menuitem スタイルをオーバーライドして foreground プロパティを設定するために使用されます

                            <ContentPresenter x:Name="HeaderHost"
                                          Grid.Column="1"
                                          Margin="{TemplateBinding Padding}"
                                          ContentSource="Header"
                                          RecognizesAccessKey="True" >

                                <ContentPresenter.Resources>
                                        <Style TargetType="{x:Type TextBlock}">
                                            <Setter Property="TextTrimming" Value="CharacterEllipsis"/>
                                            <Setter Property="FontSize" Value="11"/>
                                            <Setter Property="FontFamily" Value="Arial Unicode MS"/>
                                            <Style.Triggers>
                                                <Trigger Property="controls:TextBlockService.IsTextTrimmed" Value="True">
                                                    <Setter Property="ToolTip" Value="{Binding Text, RelativeSource={RelativeSource Self}}"/>
                                                </Trigger>
                                            </Style.Triggers>
                                        </Style>

                                </ContentPresenter.Resources>
                                </ContentPresenter>







                            <TextBlock x:Name="ShortCuts" Grid.Column="3" Margin="{TemplateBinding Padding}" >
                            </TextBlock>





                            <Popup x:Name="SubMenuPopup"
                               AllowsTransparency="true"
                               Focusable="false" Grid.IsSharedSizeScope="True"
                               IsOpen="{Binding Path=IsSubmenuOpen,
                                                RelativeSource={RelativeSource TemplatedParent}}"
                               Placement="Right"
                               PopupAnimation="{DynamicResource {x:Static SystemParameters.MenuPopupAnimationKey}}"
                               VerticalOffset="-3">
                                <Grid x:Name="SubMenu">
                                    <Border x:Name="SubMenuBorder"
                                        Background="{TemplateBinding Background}"
                                        BorderBrush="Gray"
                                        BorderThickness="1" 
                                        CornerRadius="5">
                                        <StackPanel IsItemsHost="True" KeyboardNavigation.DirectionalNavigation="Cycle" />
                                    </Border>
                                </Grid>
                            </Popup>
                        </Grid>
                    </Border>

この区切りプロパティが設定されているため、このプロパティのために、Rad メニュー項目の余分な行に移動しています

                    <Rectangle x:Name="Separator" Grid.Row="1" 
                                Height="1" Visibility="Collapsed"
