wpf - 如何在WPF中为listviewitem添加垂直线

Question

我正在尝试在 ListViewItem 的列之间放置垂直线。我尝试了给出的解决方案。但它不起作用。谁能帮我解决这个问题。我为 ListViewItem 创建了一个单独的样式。我需要在样式中添加一些属性吗？

代码是这样的

<ListView x:Key="ListView1" ItemContainerStyle="{DynamicResource ListViewItemStyle1}">
<ListView.View>
    <GridView>
        <GridViewColumn Header="{TemplateBinding GridView.ColumnCollection}">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <Border BorderBrush="#FF000000" BorderThickness="1,0,0,0" Margin="-6,-2,-6,-2">
                        <StackPanel Margin="6,2,6,2">
                            <TextBlock Text="{TemplateBinding Content}"/>
                        </StackPanel>
                     </Border>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
    </GridView>
</ListView.View>
</ListView>

从字面上看它应该有效，但它不起作用。我无法使用上面的代码添加垂直线..

这是一个带有 ListView 和两列的简短示例。诀窍是定义一个带有边框的 DataTemplate，拉伸(stretch)边框以填充单元格(请参阅 ItemContainerStyle、Style ListViewItem、H/V-ContentAligment=Stretch)并显示(在本例中)右侧和底线(通过 BorderThickness= “0,0,1,1”)。对于您的情况，请使用 BorderThickness="0,0,1,0"

    <ListView ItemsSource="{Binding}">
        <ListView.ItemContainerStyle>
            <Style TargetType="ListViewItem">
                <Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
                <Setter Property="VerticalContentAlignment" Value="Stretch"></Setter>
            </Style>
        </ListView.ItemContainerStyle>
        <ListView.Resources>
            <DataTemplate x:Key="NameTemplate">
                <Border BorderThickness="0,0,1,1" BorderBrush="LightGray" Margin="-6,0,-6,0">
                    <TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding Name}" VerticalAlignment="Center" TextTrimming="CharacterEllipsis"></TextBlock>
                </Border>
            </DataTemplate>
            <DataTemplate x:Key="ActualValueTemplate">
                <Border BorderThickness="0,0,1,1" BorderBrush="LightGray" Margin="-6,0,-6,0">
                    <TextBlock Name="ActualValueTextBlock" Margin="2,1,1,1" Text="{Binding TextMeasuredValue}" VerticalAlignment="Center"></TextBlock>
                </Border>
            </DataTemplate>
        </ListView.Resources>
        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="Name" CellTemplate="{StaticResource NameTemplate}"></GridViewColumn>
                    <GridViewColumn Header="Actual Value" CellTemplate="{StaticResource ActualValueTemplate}"></GridViewColumn>
                </GridView.Columns>
            </GridView>
        </ListView.View>
    </ListView>

编辑:
我使用了您的源代码并做了一些小的修改:

<ListView ItemContainerStyle="{DynamicResource ListViewItemStyle1}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="My Header">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <Border BorderBrush="#FF000000" BorderThickness="1,0,1,0" Margin="-6,-2,-6,-2">
                            <StackPanel Margin="6,2,6,2">
                                <TextBlock Text="{TemplateBinding Content}"/>
                            </StackPanel>
                        </Border>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
    <ListViewItem>Hello</ListViewItem>
    <ListViewItem>Stack</ListViewItem>
    <ListViewItem>Overflow</ListViewItem>
</ListView>

结果是这样的:

我在右侧添加了垂直线以获得更好的可见性，并且边框没有拉伸(stretch)到单元格的边界 - 好吧，所以它看起来有点难看。但正如您所看到的，它正在发挥作用。
