c# - 在 ListView ItemTemplate 填充中制作网格

Question

我有一个 ListView，它有一个基于网格的数据模板。 xaml如下:

<ListView ItemsSource="{Binding SomeItemSource}" HorizontalAlignment="Stretch" Height="281">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid HorizontalAlignment="Stretch" Margin="3" Width="Auto"> 
                <Grid.RowDefinitions>
                    <RowDefinition></RowDefinition>
                    <RowDefinition></RowDefinition>
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="70"></ColumnDefinition>
                    <ColumnDefinition Width="*"></ColumnDefinition>
                </Grid.ColumnDefinitions>
                <!-- Grid content here -->
                <TextBlock Text="SomeTextbox" 
                           Margin="5,5,0,0"/>

                <TextBox Grid.Column="1" 
                         Margin="0,5,0,0"
                         Text="{Binding SomeProperty, Mode=TwoWay}"
                         HorizontalAlignment="Left"
                         Width="90"/>

                <TextBlock Text="AnotherText" 
                           Grid.Column="0" 
                           Grid.Row="1"
                           Margin="5,5,0,0"/>

                <TextBox Grid.Column="1" Grid.Row="1"
                         Margin="0,5,0,0"
                         Text="{Binding AnotherProperty, Mode=TwoWay}" 
                         HorizontalAlignment="Stretch"
                         Width="300"/>
            </Grid>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

我想要的是让网格填充(拉伸(stretch))父 ListView 的整个水平宽度，但是它当前换行到其内容总和的宽度。我怎样才能实现我想要的行为？

您需要将 ListViewItem.Horizo​​ntalContentAlignment 设置为 Stretch。尝试将其添加到您的 ListView 定义中:

<ListView.ItemContainerStyle>
    <Style TargetType="{x:Type ListViewItem}">
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    </Style>
</ListView.ItemContainerStyle>
