在WPF中,要在DataGrid控件中显示行号,你可以通过自定义DataGridTemplateColumn或者使用ItemsPanelTemplate来实现。以下是两种方法:
1. **使用DataGridTemplateColumn**:
首先,创建一个包含行号和数据的模板列:
```xml
<DataGrid>
<DataGrid.Columns>
<DataGridTextColumn Header="数据" Binding="{Binding DataProperty}"/>
<DataGridTemplateColumn Header="行号">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGridRow}}, Path=Index}" />
<TextBlock Text=" - " Margin="5,0,0,0"/>
<ContentPresenter/>
</StackPanel>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
```
这里`{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGridRow}}, Path=Index}`会获取当前行的索引。
2. **使用ItemsPanelTemplate**:
如果你想让行号始终显示在每行左边,可以设置ItemsPanelTemplate为`UniformGrid`:
```xml
<DataGrid ItemsPanelTemplate="{StaticResource CustomPanel}">
<Style TargetType="DataGrid">
<Setter Property="RowHeaderWidth" Value="Auto"/>
<Setter Property="AlternatingRowBackground" Value="Transparent"/>
</Style>
</DataGrid>
<Style x:Key="CustomPanel" TargetType="UniformGrid">
<Setter Property="Rows" Value="2"/>
<Setter Property="ColumnWidth" Value="*"/>
<Setter Property="ItemHeight" Value="{DynamicResource DataGridRowHeight}"/>
<Setter Property="Margin" Value="0,0,0,5"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="ItemTemplate">
<Setter.Value>
<DataTemplate>
<Border BorderBrush="{DynamicResource DataGridRowBorder}" BorderThickness="{DynamicResource DataGridRowBorderThickness}">
<DockPanel LastChildFill="True">
<!-- 行号和主要内容 -->
<TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGridRow}}, Path=Index}" DockPanel.Dock="Left"/>
<ContentPresenter Content="{Binding}"/>
</DockPanel>
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
```
这将会在每个单元格的左上角显示行号。
