【问题描述】：
我制作了一个自定义 ListboxItem (UserControl) 并在 ListBox 中使用它。我的问题是，如果我选择一个项目，它将不会突出显示。有人知道如何解决吗？
我是否必须更改我的自定义 ListboxItem 或主页中的列表框？
提前谢谢你。
编辑：
<UserControl x:Class="Phone.CustomListBoxItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Foreground="{StaticResource PhoneForegroundBrush}"
<Grid x:Name="LayoutRoot" >
<TextBlock Name="Name" Text="" />
<TextBlock Name="Date" Text="" />
<TextBlock Name="User" Text="" />
</Grid>
这就是自定义的ListboxItem，Page只是一个Listbox和testpage.xaml.cs中生成的几个Item。
我已经应用了样式，但我不会工作：
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox Height="467" HorizontalAlignment="Left" Margin="17,16,0,0" Name="listBox1" VerticalAlignment="Top" Width="421" Style="ListBoxItemStyle">

<ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Background="{StaticResource PhoneAccentBrush}"
/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.Resources>
</ListBox>
</Grid>
</Grid>
一些建议会非常好。我现在花了几个小时来完成这个简单的操作。
