wpf <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <CheckBox HorizontalAlignment="Center" VerticalAlignment="Center" IsChecked="{Binding IsCheck,UpdateSourceTrigger=PropertyChanged}" x:Name="DTCB" Command="{Binding DataContext.SelectedCommand, RelativeSource={RelativeSource AncestorType=UserControl}}" CommandParameter="{Binding Cad_No}"> <CheckBox.InputBindings> <MouseBinding MouseAction="LeftClick" /> </CheckBox.InputBindings> </CheckBox> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn>怎么从第二行开始设置mouseaction

你可以使用 `DataGrid.RowStyle` 来为每行设置样式，并在第二行及以后的行中添加 `MouseBinding`，如下所示：

<DataGrid.RowStyle>
    <Style TargetType="DataGridRow">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type DataGridRow}">
                    <Border x:Name="DGR_Border" BorderThickness="1" BorderBrush="#E0E0E0" Margin="0,-1,0,0">
                        <SelectiveScrollingGrid>
                            <SelectiveScrollingGrid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto"/>
                                <ColumnDefinition Width="*"/>
                            </SelectiveScrollingGrid.ColumnDefinitions>
                            <SelectiveScrollingGrid.RowDefinitions>
                                <RowDefinition Height="*"/>
                                <RowDefinition Height="Auto"/>
                            </SelectiveScrollingGrid.RowDefinitions>
                            <DataGridCellsPresenter SelectiveScrollingGrid.SelectiveScrollingOrientation="{Binding AreRowDetailsFrozen, ConverterParameter={x:Static SelectiveScrollingOrientation.Vertical}, Converter={x:Static DataGrid.RowDetailsScrollingConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Grid.Column="1" x:Name="CellPresenter"/>
                            <DataGridDetailsPresenter SelectiveScrollingGrid.SelectiveScrollingOrientation="{Binding AreRowDetailsFrozen, ConverterParameter={x:Static SelectiveScrollingOrientation.Vertical}, Converter={x:Static DataGrid.RowDetailsScrollingConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Grid.Column="1" Grid.Row="1" x:Name="DetailsPresenter"/>
                            <DataGridRowHeader Grid.RowSpan="2" SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical" x:Name="RowHeader"/>
                        </SelectiveScrollingGrid>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsSelected" Value="True">
                            <Setter TargetName="DGR_Border" Property="Background" Value="#FFC5CBF9"/>
                        </Trigger>
                        <DataTrigger Binding="{Binding Cad_No}" Value="YOUR_VALUE_HERE">
                            <Setter TargetName="DTCB" Property="IsEnabled" Value="False"/>
                        </DataTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <Trigger Property="AlternationIndex" Value="1">
                <Setter Property="Background" Value="#FAFAFA"/>
            </Trigger>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Background" Value="#F2F2F2"/>
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Background" Value="#FFC5CBF9"/>
            </Trigger>
        </Style.Triggers>
    </Style>
</DataGrid.RowStyle>

在模板中，你需要使用 `ControlTemplate.Triggers` 来添加样式触发器。在这个例子中，我添加了一个数据触发器，当 `Cad_No` 的值等于你指定的值时，禁用 `CheckBox`。你需要将 `YOUR_VALUE_HERE` 替换为你想要使用的值。
