这是我正在使用的代码和显示结果的图像。最终产品具有我想要的外观,但是我认为必须有更好的方法来实现此目的。

如何在忽略网格的行和列定义的同时将椭圆与中心对齐?默认情况下,椭圆变为0,0,并放置在最顶部最左侧网格位置的红色矩形的顶部。
我试图放置在页面中,而不是放置在网格中,但是我认为页面只能具有一个content属性?
我显示的图片恰好是我想要的结果,我只是想知道是否有另一种方法来实现这一目标,而这涉及跨多个行和列的定义。
谢谢!

要在同一区域上具有多个图层,请再引入一个网格:
<Grid>
<!--layer 0-->
<Grid Background="White">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Rectangle x:Name="RedButton"
Grid.Row="0"
Grid.Column="0"
Fill="Red"
Style="{StaticResource ColorButton}"/>
<Rectangle x:Name="YellowButton"
Grid.Row="0"
Grid.Column="1"
Fill="Yellow"
Style="{StaticResource ColorButton}"/>
<Rectangle x:Name="GreenButton"
Grid.Row="1"
Grid.Column="0"
Fill="Green"
Style="{StaticResource ColorButton}"/>
<Rectangle x:Name="BlueButton"
Grid.Row="1"
Grid.Column="1"
Fill="Blue"
Style="{StaticResource ColorButton}"/>
</Grid>
<!--layer 1, covers layer 0-->
<Ellipse x:Name="CenterDot"
Fill="Black"
Width="50"
Height="50"
HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Grid>
具有白色背景和椭圆形的网格位于外部网格的同一单元格中。
