wpf - 创建 DataGrid 列分隔符

Question

有没有办法在 DataGrid 中的两个特定列之间创建可视分隔符？它不需要花哨，可能只是一条双线或更粗的边框。

Answer 1

如果是这样的



您可以使用自定义样式实现:

<Window.Resources>
    <Style x:Key="DataGridColumnSeparatorStyle" TargetType="DataGridCell">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Fill="Gray"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

<DataGrid x:Name="dataGrid" AutoGenerateColumns="False">        
    <DataGrid.Columns>
        <DataGridTextColumn Header="Start"/>
        <DataGridTextColumn Header="End"/>
        <!-- Separator column -->
        <DataGridTemplateColumn MinWidth="0" Width="2" CellStyle="{StaticResource DataGridColumnSeparatorStyle}"/>
        <DataGridTextColumn Header="Start"/>
        <DataGridTextColumn Header="End"/>
    </DataGrid.Columns>
</DataGrid>

如果您通过自动生成列或其他方式在代码隐藏中生成列，您仍然可以通过从 XAML 获取资源来创建分隔列:

DataGridTextColumn s1 = new DataGridTextColumn() { Header = "Start" };
DataGridTextColumn s2 = new DataGridTextColumn() { Header = "Start" };
DataGridTextColumn e1 = new DataGridTextColumn() { Header = "End" };
DataGridTextColumn e2 = new DataGridTextColumn() { Header = "End" };

DataGridTemplateColumn column = new DataGridTemplateColumn();
column.MinWidth = 0;
column.Width = 2;

var separatorStyle = (Style)FindResource("DataGridColumnSeparatorStyle");
column.CellStyle = separatorStyle;

dataGrid.Columns.Add(s1);
dataGrid.Columns.Add(e1);
dataGrid.Columns.Add(column);
dataGrid.Columns.Add(s2);
dataGrid.Columns.Add(e2);
