我希望ListItems以其橙色背景擴(kuò)展為L(zhǎng)istbox的整個(gè)寬度。目前它們只與FirstName + LastName一樣寬。我已將每個(gè)元素設(shè)置為：HorizontalAlignment =“Stretch”。我希望ListboxItems的背景隨著用戶拉伸列表框而擴(kuò)展，因此我不想輸入絕對(duì)值。我需要做什么才能使ListBoxItems的背景顏色填充ListBox的寬度？<Window x:Class="TestListBoxSelectedItemStyle.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TestListBoxSelectedItemStyle"
Title="Window1" Height="300" Width="300">
<Window.Resources>
<local:CustomerViewModel x:Key="TheDataProvider"/>
<DataTemplate x:Key="CustomerItemTemplate">
<Border CornerRadius="5" Background="Orange" HorizontalAlignment="Stretch" Padding="5" Margin="3">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" Width="Auto">
<TextBlock HorizontalAlignment="Stretch">
<TextBlock.Text>
<MultiBinding StringFormat="{}{0} {1}">
<Binding Path="FirstName"/>
<Binding Path="LastName"/>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</StackPanel>
</Border>
</DataTemplate>
</Window.Resources>
<Grid>
<ListBox ItemsSource="{Binding Path=GetAllCustomers, Source={StaticResource TheDataProvider}}"
ItemTemplate="{StaticResource CustomerItemTemplate}"/>
</Grid></Window>
如何讓ListBox ItemTemplate水平拉伸ListBox的整個(gè)寬度？
