WPF ListBox turn off hover effect
提问by beta
I've found and tried many solutions on the internet which should allow me to disable the hover effectof my WPF ListBox but none of them seemed to work for me. This screenshot shows the hover effect I'd like to hide or get rid of:
我在互联网上找到并尝试了许多解决方案，这些解决方案应该允许我禁用WPF ListBox的悬停效果，但似乎没有一个对我有用。此屏幕截图显示了我想隐藏或摆脱的悬停效果：
This is (a simplified version) of the XAML code I currently have:
这是我目前拥有的 XAML 代码的（简化版本）：
<ListBox ItemsSource="{Binding Logs}" Grid.Column="1" Width="800" Height="100" >
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Style.Triggers>
<Trigger Property="Control.IsMouseOver" Value="True">
<Setter Property="Control.Background" Value="Transparent" />
</Trigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
However, it doesn't seem to work for me for a reason or another. Could my parent ListBox (the one in the background) or another control override it's child's style by any chance? (I already tried to override the parents style as well)
但是，出于某种原因，它似乎对我不起作用。我的父 ListBox（背景中的那个）或另一个控件是否可以覆盖它的子样式？（我也已经尝试过覆盖父母的风格）
