【问题描述】：
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用作网格的按钮，但保留按钮的所有功能。所以它是可点击的，但不会挤压内容。 （有点像 Windows Tiles）
目前要实现这一点，我可以在按钮控件中放置一个网格，但随后我必须手动设置高度和宽度。我希望通过动态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！也可以接受任何干净的解决方案。

作为参考，这就是我过去制作按钮的方式。它完成了工作，但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>
