wpf样式触发器鼠标划过按钮问题

<Window x:Class="WpfTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style x:Key="Style1" TargetType="{x:Type Button}">
            <Setter Property="FontSize" Value="16"></Setter>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="BlanchedAlmond"></Setter>
                    <Setter Property="Cursor" Value="Hand" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </Window.Resources>
    <Grid>
        <Button Style="{StaticResource Style1}" Margin="23,32,95,139" Content="按钮1"/>
    </Grid>
</Window>

请问前辈们，为什么鼠标划过按钮，然后停留在按钮上面，背景色只显示一下BlanchedAlmond颜色，然后又恢复默认的颜色，谢谢！

不知道你的是怎么回事，你可以尝试换一种写法，给Button一个name属性，比如Name=“Button1”，代码这样写：

<Trigger Property="IsMouseOver" Value="True">
                                        <Setter Property="Background" TargetName="Button1">
                                            <Setter.Value>
                                                <SolidColorBrushColor="BlanchedAlmond" />
                                            </Setter.Value>
                                        </Setter>
									</Trigger>

我的代码是这样写的，显示正常，不知道你的怎么回事。
