Question

我正在尝试找到一种更清晰的解决方案，以按照我想要的方式显示按钮的内容。

基本上，我的目标是创建一个用作网格的按钮，但保留Button的所有功能。所以它是可点击的，但不会压缩内容。（类似于Windows Tiles）

为了实现这一点，我可以在按钮控件中放置一个网格，但是我必须手动设置高度和宽度。我希望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，但我没有太多运气。任何帮助表示赞赏！也适用于任何清洁解决方案。

作为参考，这就是我过去做按钮的方式。它完成了工作，但屏幕尺寸的变化并不动态。

<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>
