xaml - 如何在整个网格上拉伸(stretch)按钮，xaml

Question

我在整个网格上拉伸(stretch)按钮时遇到问题。
我的代码如下所示:

<Grid x:Name="LayoutRoot" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="2*"/>
        <RowDefinition Height="8*"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <StackPanel Grid.Column="5" Grid.Row="1" Width="Auto" Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <Button Content="Search" Background="#FF13D38D" Click="searchButton_Click" FontSize="48"/>
    </StackPanel>
</Grid>

但它对我不起作用，并且在整个网格上拉伸(stretch)按钮，我尝试了 maxwidth/maxheight 但它也没有正常工作有人知道吗？

TL;DR:
删除 StackPanel (见 Charleh's comment below question)。

问题已解决

<Grid x:Name="LayoutRoot" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="2*"/>
        <RowDefinition Height="8*"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Button Content="Search" Background="#FF13D38D" Click="searchButton_Click" FontSize="48" Grid.Column="5" Grid.Row="1"/>
</Grid>
