我目前正在使用XAML设计一个Windows 8商店应用程序,但我有一个小的尺寸问题.我有一个带有DataTemple的ListView.

我的ListView和DataTemplate的代码如下:

<ListView x:Name="listPageItems"
          Grid.Row="1"
          SelectionMode="Extended"
          IsSwipeEnabled="False"
          ItemsSource="{Binding Mode=OneWay, Source={StaticResource items}}"
          ItemTemplate="{StaticResource NavigationItemTemplate}"
          ScrollViewer.VerticalScrollBarVisibility="Visible">

</ListView>

<DataTemplate x:Key="NavigationItemTemplate">    
        <Grid Height="75">
            <Grid.RowDefinitions>
                <RowDefinition Height="1.6*" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <Rectangle Fill="White" />
            <Rectangle Fill="{StaticResource SSEGreenBrush}"
                       Grid.Row="1" />
            <Border BorderThickness="2"
                    BorderBrush="{StaticResource SSEGreenBrush}"
                    Grid.RowSpan="2" />
            <TextBlock x:Name="textTitle"
                       Text="{Binding ClientName}"
                       Style="{StaticResource TitleTextStyle}"
                       Foreground="{StaticResource SSEBlueBrush}"
                       Margin="10,5,5,5" />
            <StackPanel Orientation="Horizontal"
                        Grid.Row="1"
                        HorizontalAlignment="Stretch">
                <TextBlock Text="Last Edit :"
                           Style="{StaticResource SubtitleTextStyle}"
                           Foreground="{StaticResource SSEBlueBrush}"
                           Margin="3,0,0,3"
                           VerticalAlignment="Center" />
                <TextBlock Text="SurveyDate"
                           Style="{StaticResource SubtitleTextStyle}"
                           Foreground="{StaticResource SSEBlueBrush}"
                           Margin="3,0,0,3"
                           VerticalAlignment="Center" />
            </StackPanel>
        </Grid>
    </DataTemplate>

列表视图位于网格列中,其固定宽度为240. …

我在我的UWP应用程序中有ListView,并希望它设置100%的显示宽度.

这是我在xaml文件中的代码

<Page
x:Class="TestApp.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TestApp"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <ListView x:Name="PostList" ItemsSource="{Binding PostsList}" HorizontalAlignment="Left" Height="720" VerticalAlignment="Top" Width="1280">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid x:Name="GridInf"  Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,1,1">
            </Grid>
            </DataTemplate>
    </ListView.ItemTemplate>
    </ListView>
</Grid>

我试着这样做 Width="100%"

但它不起作用？

我怎么能做到的？
