WPF Xaml自定义样式ListBox中的选定项样式

I have a ListBox that scrolls images horizontally.

我有一个ListBox水平滚动图像。

I have the following XAML I used blend to create it. It originally had a x:Key on the Style TaregetType line, MSDN said to remove it, as I was getting errors on that. Now I'm getting this error:

我有以下XAML我用混合来创建它。它最初在Style TaregetType行上有一个x：Key，MSDN表示将其删除，因为我收到了错误。现在我收到这个错误：

Error 3 Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.

错误3在使用ItemsSource时，操作无效。使用ItemsControl.ItemsSource访问和修改元素。

I don't understand how to apply all of this junk that way, I've tried several things, nothing is working.

我不明白如何以这种方式应用所有这些垃圾，我尝试了几件事，没有任何工作。

My goal is to have the selected item's background be white, not blue. Seems like a lot of work for something so small!

我的目标是让所选项目的背景为白色，而不是蓝色。对于这么小的东西来说，似乎做了很多工作！

Thanks.

谢谢。

Wrap the Style Tag with an ItemContainerStyle as below:

使用ItemContainerStyle包装样式标记，如下所示：

<ListBox ItemsSource="{Binding Source={StaticResource WPFApparelCollection}}"
         Grid.Row="1" Margin="2,26,2,104"
         ScrollViewer.VerticalScrollBarVisibility="Hidden"
         ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
         SelectionMode="Single"
         x:Name="list1" MouseLeave="List1_MouseLeave" MouseMove="List1_MouseMove" 
         Style="{DynamicResource ListBoxStyle1}"  >

        <ListBox.ItemContainerStyle>
            <Style TargetType="{x:Type ListBoxItem}">
                <Setter Property="Background" Value="Transparent"/>
            </Style>
<!-- the rest of your code,  but close the ItemContainerStyle -->
        </ListBox.ItemContainerStyle> 
    </ListBox>

I tried the above solution but it didnt worked as expected so I found another way to solve my problem which is to disable selection for listbox

我尝试了上面的解决方案，但它没有按预期工作，所以我找到另一种方法来解决我的问题，即禁用列表框的选择

this is what I did

这就是我所做的

<ListBox.ItemContainerStyle>
    <Style TargetType="{x:Type ListBoxItem}">
         <Setter Property="Focusable" Value="False"/>
     </Style>
</ListBox.ItemContainerStyle>
