推荐答案

您可以在StackPanel周围放置一个不可见的Border元素，然后使用带有DataTrigger的Style将鼠标移到StackPanel上时使其可见:

You could put an invisible Border element around the StackPanel and then make it visible when the mouse moves over the StackPanel using a Style with a DataTrigger:

<Border BorderThickness="10" HorizontalAlignment="Left" VerticalAlignment="Top">
            <StackPanel x:Name="sp" Background="Transparent" Width="100" Height="100">
            </StackPanel>
            <Border.Style>
                <Style TargetType="Border">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Path=IsMouseOver, ElementName=sp}" Value="True">
                            <Setter Property="BorderBrush" Value="AliceBlue"/>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </Border.Style>
        </Border>

确保StackPanel设置了Background(可以将其设置为Transparent或某种颜色的笔刷)，否则IsMouseOver属性将不会设置为true.

Make sure that the StackPanel has a Background set (you could set it to Transparent or some colour brush), othwerwise the IsMouseOver property won't be set to true.
