ListView填充父级,屏幕或其他任何内容的宽度

Question

我试图从Observable Collection显示一些数据到ListView.绑定工作正常.我无法解决的唯一问题是ListView的布局.我使用一个包含2行的Grid来分割我的View.ListView是第二行之一.我只尝试使用*来设置大多数来源中建议的列和行.ListView的代码就是这个.

<Grid Grid.Row="1" Margin="10,0,10,0" HorizontalAlignment="Stretch">
    <ListView ItemsSource="{Binding Collection}" HorizontalAlignment="Stretch">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid HorizontalAlignment="Stretch">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding Currency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

当我对包含ListView和ListView本身的网格使用Horizo​​ntalAlignment ="Stretch"时,数据显示在左侧而不获取父视图的整个宽度.当我明确地将Width设置为某​​个值(即380)时,它显示OK.

<Grid Grid.Row="1" Margin="10,0,10,0">
    <ListView ItemsSource="{Binding Collection}" Width="380">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid Width="380">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding ValueInCurrency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

但我想知道一种不使用隐式值的更好方法,但*.

试试这个.之后添加以下jus</ListView.ItemTemplate>

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    </Style>
</ListView.ItemContainerStyle>
