UWP XAML 按钮内容模板

Question

我正在尝试找到一种更简洁的解决方案来以我想要的方式显示按钮控件的内容。

基本上，我的目标是制作一个功能类似于网格但保留按钮所有功能的按钮。所以它是可点击的，但不会挤压内容。（有点像 Windows 瓷砖）

目前要完成此操作，我可以在按钮控件中放置一个网格，但我必须手动设置高度和宽度。我希望它通过动态和拉伸到按钮的宽度和高度。

这是我正在尝试编辑的当前模板。我愿意为 ContentTemplate 创建自定义样式，但运气不佳。任何帮助表示赞赏！也对任何干净的解决方案开放。

供参考，这就是我过去做按钮的方式。它完成了工作，但它对屏幕尺寸的变化不是动态的。

<Button x:Name="TileButton" Margin="2" Grid.Column="1" Grid.ColumnSpan="1" Grid.Row="3" Style="{StaticResource ButtonTileStyle}">
        <Grid HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="-8,-4" Width="113" Height="123">
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="*"/>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>

            <Image Grid.Row="1" Source="..."/>
            <TextBlock x:Name="Label" Text="Label" Grid.Row="2" VerticalAlignment="Bottom" Margin="5,0,0,2" HorizontalAlignment="Stretch" TextAlignment="Left"/>
        </Grid>
    </Button>
