ListView fill the width of parent, screen or whatever
提问by Andreas777
I am trying to display some data from an Observable Collection to a ListView. Binding is working fine. My only problem I cannot fix is the layout of the ListView.I use a Grid with 2 rows to split my View. The ListView is one the second row. I only try to use * for setting Columns and Rows as suggested in most sources. The code for the ListView is this.
我正在尝试将 Observable 集合中的一些数据显示到 ListView。绑定工作正常。我唯一无法解决的问题是 ListView 的布局。我使用带有 2 行的 Grid 来拆分我的视图。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 的代码是这样的。
<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>
When I use HorizontalAlignment="Stretch" for the Grid that contains the ListView and the ListView itself the data is displayed on the left side without getting the whole width of parent View. When I explicitly set Width to some value (i.e.380) it displays OK.
当我对包含 ListView 和 ListView 本身的 Grid 使用 HorizontalAlignment="Stretch" 时，数据显示在左侧，而没有获得父视图的整个宽度。当我将 Width 显式设置为某个值 (ie380) 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>
But I want to know a better way to not use implicit values, but *.
但我想知道一种更好的方法来不使用隐式值，而是使用 *.

Try this. Add the following jus after </ListView.ItemTemplate>
尝试这个。在后面添加以下内容</ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListView.ItemContainerStyle>
