Question

我创建了下一个ListView

 <ListView Height="Auto" MaxHeight="300" Margin="5,5,5,0" BorderBrush="Transparent"
                        ItemsSource="{Binding SelectedFolders}" BorderThickness="0" >      
                    <ListView.View>
                             <GridView>
                <GridViewColumn Header="Folder Name" Width="600">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                                 <TextBlock Text="{Binding FolderName}" FontSize="16" Foreground="Black" Margin="2,2" HorizontalAlignment="Left">
                                    <TextBlock.ToolTip>
                                        <TextBlock Text="{Binding FolderFullPath}"/>                        
                                    </TextBlock.ToolTip>                        
                                </TextBlock>                        
                        </DataTemplate>             
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>           

                <GridViewColumn Header="Size" Width="70">
                      <GridViewColumn.CellTemplate>
                        <DataTemplate>
                                 <TextBlock Text="{Binding FolderSize}" FontSize="16" Foreground="Black" Margin="2,2"  HorizontalAlignment="Left">
                                    <TextBlock.ToolTip>
                                        <TextBlock Text="{Binding FolderFullPath}"/>                        
                                    </TextBlock.ToolTip>                        
                                </TextBlock>                        
                        </DataTemplate>             
                    </GridViewColumn.CellTemplate>            
                </GridViewColumn>
            </GridView>                   
            </ListView.View>   
  </ListView>

我正在尝试删除列分隔符但没有成功。这就是它现在的样子：

在图片中，您可以看到尺寸列线，我该如何删除它们？

只需创建自己的样式GridViewColumnHeader ...

这是一个简单的示例，除了TextBlock之外没有任何东西（当然，没有垂直线）：

<Window.Resources>
    <Style x:Key="GridHeader" TargetType="{x:Type GridViewColumnHeader}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type GridViewColumnHeader}">
                    <TextBlock Text="{TemplateBinding Content}" Padding="5" Width="{TemplateBinding Width}" TextAlignment="Right" />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

</Window.Resources>

用法：

<ListView Height="Auto" MaxHeight="300" Margin="5,5,5,0" BorderBrush="Transparent"
          ItemsSource="{Binding ReferenceCollection}" BorderThickness="0">
        <ListView.View>
            <GridView ColumnHeaderContainerStyle="{StaticResource GridHeader}">
               ....

打开表达式混合并编辑GridViewColumnHeader样式。我是为你做的。

<LinearGradientBrush x:Key="GridViewColumnHeaderBackground" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FFFFFFFF" Offset="0"/>
        <GradientStop Color="#FFFFFFFF" Offset="0.4091"/>
        <GradientStop Color="#FFF7F8F9" Offset="1"/>
    </LinearGradientBrush>
    <LinearGradientBrush x:Key="GridViewColumnHeaderBorderBackground" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FFF2F2F2" Offset="0"/>
        <GradientStop Color="#FFD5D5D5" Offset="1"/>
    </LinearGradientBrush>
    <LinearGradientBrush x:Key="GridViewColumnHeaderHoverBackground" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FFBDEDFF" Offset="0"/>
        <GradientStop Color="#FFB7E7FB" Offset="1"/>
    </LinearGradientBrush>
    <LinearGradientBrush x:Key="GridViewColumnHeaderPressBackground" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FF8DD6F7" Offset="0"/>
        <GradientStop Color="#FF8AD1F5" Offset="1"/>
    </LinearGradientBrush>

    <Style TargetType="{x:Type GridViewColumnHeader}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type GridViewColumnHeader}">

如果需要，你可以用同样的方式修改它。
