Xaml Xamarin母版页-在菜单中显示/隐藏分隔符行

如何在母版页的菜单中显示/隐藏分隔符行？目前，所有线路似乎都已启用，但我不知道它们来自何处。我想禁用除“Slaap”和“Persoonlike gegevens”之间的行之外的所有行。在这张图片中，看起来只有两条线，但实际上你可以清楚地看到它们

母版页.xaml

首先，您的列表视图应具有

分隔符visibility=None

在您的

local:MasterPageItem

中添加一个新属性

IsSeparator

，以确定将分隔哪个元素

然后，在listview中

<ListView x:Name="listView" SeparatorVisibility="None" x:FieldModifier="public">
        <ListView.ItemsSource>
            <x:Array Type="{x:Type local:MasterPageItem}">
                <local1:MasterPageItem Title="Home" IconSource="contacts.png" TargetType="{x:Type local:ItemsPage}" />
                <local1:MasterPageItem Title="Sport" IconSource="contacts.png" TargetType="{x:Type local:SportPage}" />
                <local1:MasterPageItem Title="Voeding" IconSource="reminders.png" TargetType="{x:Type local:VoedingPage}" />
                <local1:MasterPageItem IsSeparator="true" Title="Slaap" IconSource="todo.png" TargetType="{x:Type local:SlaapPage}" />
                <local1:MasterPageItem Title="Persoonlijke Gegevens" IconSource="todo.png" TargetType="{x:Type local:GegevensGewichtDoel}"/>
            </x:Array>
        </ListView.ItemsSource>
        <ListView.ItemTemplate>
            <DataTemplate>
                <ViewCell>
                    <Grid Padding="5,10">
                        <Grid.RowDefinitions>
                            <RowDefinition Height ="*"/>
                            <RowDefinition Height ="1"/>
                        <Grid.RowDefinitions/>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="30"/>
                            <ColumnDefinition Width="*" />
                        </Grid.ColumnDefinitions>
                        <Image Source="{Binding IconSource}" />
                        <Label Grid.Column="1" Text="{Binding Title}" FontSize="17" />

                        <BoxView Grid.Row="1" Grid.ColumnSpan="2" HeightRequest="1" Color="Red" IsVisible="{Binding IsSeparator}">
                    </Grid>
                </ViewCell>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

谢谢您的回复。

IsSeperator

应该只是一个布尔值吗？我这样做了，得到了以下结果：。怎么了？我忘了添加BoxView的行（即Grid.Row=“1”），请检查我编辑的答案。是的，IsSeparator只是一个bool，以便直接绑定到IsVisibleProperty@J.K.Harthoorn如果有效，不要忘记标记为正确并向上投票！：）似乎没有修复它，结果如下：
