Question

我注意到控件的第一个列标题和左边缘之间存在间隙。我该如何删除它？

Answer 1

您可以减少Padding的{{1}}和ListView的{{1}}：

Margin

GridViewHeaderRowPresenter

Answer 2

这些代码可以工作，将其添加到Window或App.xaml的资源标签中：

        <!--This Sytle For Deletion of the Margin in Header-->
        <Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}"
   TargetType="ScrollViewer">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ScrollViewer">
                        <Grid Background="{TemplateBinding Background}">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="*" />
                                <ColumnDefinition Width="Auto" />
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="*" />
                                <RowDefinition Height="Auto" />
                            </Grid.RowDefinitions>

                            <DockPanel Margin="{TemplateBinding Padding}">
                                <ScrollViewer DockPanel.Dock="Top"
                      HorizontalScrollBarVisibility="Hidden"
                      VerticalScrollBarVisibility="Hidden"
                      Focusable="false">
                                    <GridViewHeaderRowPresenter Margin="0"
                                      Columns="{Binding Path=TemplatedParent.View.Columns,

                                      ColumnHeaderTemplateSelector="{Binding

                                      SnapsToDevicePixels="{TemplateBinding
            SnapsToDevicePixels}" />
                                </ScrollViewer>

                                <ScrollContentPresenter Name="PART_ScrollContentPresenter"
                                KeyboardNavigation.DirectionalNavigation="Local"

                            <ScrollBar Name="PART_HorizontalScrollBar"
