Richtextbox上的网格线wpf

Question

我想知道你是否可以在RichTextBox中分隔每一行的线条，就像在普通纸上一样。我一直在寻找没有运气的人，如果有人知道怎么做，我会很感激。谢谢！

Answer 1

 <RichTextBox TextBlock.LineHeight="20" TextBlock.LineStackingStrategy="BlockLineHeight" Padding="20,10,20,20">
    <FlowDocument>
        <Paragraph>
            Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem. Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum. Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.</Paragraph>

    <RichTextBox.Background>
        <DrawingBrush TileMode="Tile" Stretch="None" Viewport="0,0,20,20" ViewportUnits="Absolute" Opacity="0.1">
            <DrawingBrush.Drawing>
                <GeometryDrawing>
                    <GeometryDrawing.Pen>
                        <Pen Brush="RoyalBlue" />
                    </GeometryDrawing.Pen>
                    <GeometryDrawing.Geometry>
                        <LineGeometry StartPoint="0,0" EndPoint="20,0"/>

                </GeometryDrawing>
            </DrawingBrush.Drawing>
        </DrawingBrush>
    </RichTextBox.Background>
</RichTextBox>

我想出的最好的想法是在网格中有一个RichTextBox透明背景，可见网格线：

<Grid x:Name="grid" ShowGridLines="True" Height="50" Width="100">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <RichTextBox Grid.Row="0" x:Name="rtb" Height="50" Width="100" Grid.RowSpan="3" Background="Transparent"/>
</Grid>
