C# Gridview内容拉伸UWP

在xaml中，是否可以使GridView的内容拉伸，以便在更改GridView的宽度时，这些项可以处理拉伸？我尝试使用HorizontalContentAlignment，但它不起作用

MainPage.xaml：

 <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <GridView x:Name="GridViewItemList" HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch" ItemContainerTransitions="{x:Null}" Margin="0,50,0,0" SizeChanged="GridViewItemList_SizeChanged">
        <GridViewItem Content="Item" Width="100" Height="100" HorizontalContentAlignment="Center" Background="#FF2D7496" Foreground="White" FontSize="36"/>
        <GridViewItem Content="Item" Width="100" Height="100" HorizontalContentAlignment="Center" Background="#FF2D7496" Foreground="White" FontSize="36"/>
        <GridViewItem Content="Item" Width="100" Height="100" HorizontalContentAlignment="Center" Background="#FF2D7496" Foreground="White" FontSize="36"/>
        <GridViewItem Content="Item" Width="100" Height="100" HorizontalContentAlignment="Center" Background="#FF2D7496" Foreground="White" FontSize="36"/>
        <GridViewItem Content="Item" Width="100" Height="100" HorizontalContentAlignment="Center" Background="#FF2D7496" Foreground="White" FontSize="36"/>

            <Style TargetType="GridView">

                <Setter Property="Margin" Value="5"/>
            </Style>
        </GridView.Style>
    </GridView>
</Grid>

我希望，随着GridView宽度的变化，项目分布在GridView的整个宽度上

谢谢您的帮助。

您应该查看的是。此控件在这方面非常智能，可以根据需要自动拉伸控件，以使行均匀填充，并且两侧都没有剩余空间。

是否希望固定大小的项目填充gridview中的可用空间？
