文本框不水平拉伸

Question

我无法水平拉伸文本框以适合其容器。

注意：

我确实设置了 HorizontalAlignment 属性。
我也试过将文本框的宽度绑定到它的容器宽度。

都不适合我。

    <ListView Grid.Row="1" Grid.Column="0" ItemsSource="{Binding ConsoleLines}" Background="Black" >
        <ListView.ItemTemplate>
            <DataTemplate>
                <TextBox Text="{Binding ElementName=UserControl, Path=DataContext.Command, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
                         TextChanged="OnTextChanged" KeyDown="OnKeyDown" 
                         HorizontalAlignment="Stretch" Padding="5" Background="Black" Foreground="LightGray"  />
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

Answer 1

尝试将 ListView.HorizontalContentAlignment Property 设置为 Stretch。来自链接页面：

... you can set the HorizontalContentAlignment property to Stretch, which stretches the child element to fill the allocated space of the parent element

您一定误解了答案，因为它确实会在 GridView 的整个宽度上拉伸每个项目。试试这个：

<ListView Grid.Row="1" Grid.Column="0" ItemsSource="{Binding ConsoleLines}" 
    Background="Black" HorizontalContentAlignment="Stretch">
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBox Text="Some simple text" Background="White" 
                Foreground="LightGray"  />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

Answer 2

您应该设置 ListView 的 HorizontalContentAlignment="Stretch"

<ListView ItemsSource="{Binding Collection, Source={StaticResource viewmodel}}" Background="Black" HorizontalContentAlignment="Stretch" >
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBox HorizontalAlignment="Stretch" Padding="0" Background="Green" Foreground="White" Text=""  />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
