在 Blend 中删除 ListView 标题边框

Question

我正在努力在 Blend for VS 2015 中设置 ListView 的样式。

Border image

到目前为止，我正在尝试删除边框但没有成功。 老实说，我不知道要编辑哪个控件，因为我是 XAML 和 Blend 的新手。 另外，如果我想编辑文本样式和边距，我必须在哪里查看？

任何提示都会非常有帮助！

编辑：这是我当前的模板。 （当前没有添加任何样式）

   <ListView x:Name="osebe_listView" Margin="0,0,40,0"  SelectionMode="Multiple" BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Hidden" SelectionChanged="osebe_lw_SelectionChanged">

您需要覆盖GridViewColumnHeader 的ControlTemplate。

您可以通过在 Blend 中右键单击 GridViewColumnHeader 元素并选择“编辑模板”->“编辑副本”来复制默认模板，然后根据您的要求对其进行修改：

<ListView.Resources>
    <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 x:Key="GridViewColumnHeaderGripper" TargetType="{x:Type Thumb}">
        <Setter Property="Canvas.Right" Value="-9"/>
        <Setter Property="Width" Value="18"/>
