如何在WPF中的listview中的Columnheader和Data行之间删除分隔符边框行

Posted 2021-03-26

我正在VS2017制作一个WPF程序。但我不知道如何删除Columnheader和Data行之间的垂直分隔符。

我想删除上面图像标题的下边框。

答案

看起来你在谈论这个：你需要编辑容器样式，如果你想在那些状态上改变颜色，我还注释了Mouse Over和IsPressed取消注释。并且还注意到风格的背景颜色。

你的ListView

<Grid>
    <ListView>
        <ListView.View>
            <GridView ColumnHeaderContainerStyle="{StaticResource GridViewHeaderStyle}">
                <GridViewColumn Header="이것이 열 1입니다."  Width="250" />
