如何在WPF中为listviewitem添加垂直行

Question

我正在尝试在ListViewItem中的列之间放置垂直线.我试过给出的解决方案.但它不起作用.任何人都可以帮我解决这个问题.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>

字面上它应该工作,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.诀窍是定义一个带边框的DataTemplate,拉伸边框以填充单元格(参见ItemContainerStyle,Style ListViewItem,H/V-ContentAligment = Stretch)并显示(在本例中)右边和底线(通过BorderThickness = "0,0,1,1").对于您的情况使用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进行了一些小修改:

<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条以获得更好的可视性,并且边框没有拉伸到单元格的边界 - 好吧,所以它看起来有些难看.但正如你所看到的,它正在发挥作用.

Answer 2

尝试为边框的背景着色以使其可见

例:

<Border BorderBrush="#FF000000" Background="Red" BorderThickness="1,0,1,0" Margin="-6,-2,-6,-2">

如果您在内容后面看到一个红色矩形,则可以使用Margin和BorderThickness的值进行进一步调试.
