提到这个问题，我尝试将网格线用于我的用户控件。在设计时控件看起来不错，但是当我尝试将组件插入主窗口时，所有网格线都消失了，取而代之的是那个丑陋的灰色角落：

<UserControl x:Class="mx_sachdaten.View.FormWorkspaceView"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" Loaded="FormWorkspaceView_Loaded"
         d:DesignHeight="400" d:DesignWidth="400">
    <UserControl.Resources>
        <DrawingBrush x:Key="FormCanvasGridTile" Stretch="None" TileMode="Tile" 
                  Viewport="0,0,30,30" ViewportUnits="Absolute">
            <DrawingBrush.Drawing>
                <GeometryDrawing>
                    <GeometryDrawing.Geometry>
                        <GeometryGroup>
                            <LineGeometry StartPoint="0,0" EndPoint="30,0" />
                            <LineGeometry StartPoint="30,0" EndPoint="30,30" />
                            <LineGeometry StartPoint="30,30" EndPoint="0,30" />
                            <LineGeometry StartPoint="0,30" EndPoint="0,0" />
                        </GeometryGroup>
                    </GeometryDrawing.Geometry>
                    <GeometryDrawing.Pen>
                        <Pen Thickness="1" Brush="LightGray" />
                    </GeometryDrawing.Pen>
                    <GeometryDrawing.Brush>White</GeometryDrawing.Brush>
                </GeometryDrawing>
            </DrawingBrush.Drawing>
        </DrawingBrush>
    </UserControl.Resources>
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="Auto" />
        </Grid.ColumnDefinitions>

        <Canvas Grid.Column="0" x:Name="FormCanvas" Background="{StaticResource FormCanvasGridTile}"
            MouseLeftButtonDown="FormCanvas_MouseLeftButtonDown" VerticalAlignment="Stretch"
            HorizontalAlignment="Stretch" />
        <ToolBarTray Grid.Column="1" Orientation="Vertical">
            <ToolBar Band="1">
                <Button Content="Label" HorizontalAlignment="Right" />
                <Button Content="TextBox" HorizontalAlignment="Right" />
                <Button Content="Button" HorizontalAlignment="Right" />
            </ToolBar>
        </ToolBarTray>
    </Grid>
</UserControl>

结果：用户控件预览

这就是它在我的主窗口上的样子：主窗口

您知道为什么在将用户控件嵌入我的窗口时我的背景磁贴无法正常工作吗？

尝试这个：

<Border>
    <Border.Background>
        <VisualBrush TileMode="Tile"
            Viewport="0,0,50,50" ViewportUnits="Absolute" 
            Viewbox="0,0,50,50" ViewboxUnits="Absolute">
            <VisualBrush.Visual>
                <Rectangle Stroke="Darkgray" StrokeThickness="1" Height="50" Width="50"
                StrokeDashArray="5 3"/>
            </VisualBrush.Visual>
        </VisualBrush>
    </Border.Background>
</Border>
