每次我选择一个项目时，列表框上不再显示图像

问题：

当从ListBoxSource到ListBoxDisplay进行一些绑定时，我得到了答案，但是发生了奇怪的事情：

项目的选择和取消选择工作正常，并在名为"ListBoxDetails "的另一个 ListBox 上准确显示所选项目，但每次我选择一个项目时，图像都会消失，但选择突出显示仍然存在，但其中没有更多图像。(即使没有更多的图像，您仍然可以取消选择它，因为屏幕空间仍然存在(

注意：我在列表框源(选择模式=多个(仅图像中没有其他控件

代码 XAML：

    <Window.Resources>
    <DataTemplate x:Key="ItemTemplate">
        <WrapPanel Height="149" Orientation="Horizontal" Width="193">
            <Image HorizontalAlignment="Left" Height="128" Width="180" Margin="0"/>
        </WrapPanel>
    </DataTemplate>
    <ItemsPanelTemplate x:Key="ItemsPanelTemplate1">
        <StackPanel Orientation="Horizontal"/>
    </ItemsPanelTemplate>
    <ItemsPanelTemplate x:Key="ItemsPanelTemplate2">
        <UniformGrid x:Name="UniformGridImageList"/>
    </ItemsPanelTemplate>
</Window.Resources>
<Grid x:Name="LayoutRoot">
    <ListBox x:Name="ListBoxSource" Width="450" Margin="9,3,442,178"  ItemsPanel="{DynamicResource ItemsPanelTemplate2}" SelectionMode="Multiple" d:LayoutOverrides="GridBox" HorizontalAlignment="Left" />     
    <ListBox Name="ListBoxDisplay" Height="659" HorizontalAlignment="Right" Margin="460,5,0,0"  VerticalAlignment="Top" Width="382" ItemsSource="{Binding ElementName=ListBoxSource, Path=SelectedItems}" />
    <Button x:Name="buttonLoadImages" Content="Button" HorizontalAlignment="Left" Height="51" Margin="33,0,0,70" VerticalAlignment="Bottom" Width="183" Style="{DynamicResource ButtonStyle1}" Click="buttonLoadImages_Click"/>
    <Button Content="Clear" Height="55" HorizontalAlignment="Right" Margin="0,717,442,0" Name="buttonClearListBox" VerticalAlignment="Top" Width="177" Click="button1_Click" />
