属性触发器通常是在Style和ControlTemplate中使用的，在UserControl的XAML代码中怎么样使用属性触发器呢？

<UserControl x:Class=”WpfApplication10.UserControl2″
xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
xmlns:mc=”http://schemas.openxmlformats.org/markup-compatibility/2006″
xmlns:d=”http://schemas.microsoft.com/expression/blend/2008″
mc:Ignorable=”d”
d:DesignHeight=”300″ d:DesignWidth=”300″>
<UserControl.Style>
<Style TargetType=”UserControl”>
<Style.Triggers>
</Style.Triggers>
</Style>
</UserControl.Style>
<Grid>
xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
xmlns:mc=”http://schemas.openxmlformats.org/markup-compatibility/2006″
xmlns:d=”http://schemas.microsoft.com/expression/blend/2008″
mc:Ignorable=”d”
d:DesignHeight=”300″ d:DesignWidth=”300″>
<UserControl.Style>
<Style TargetType=”UserControl”>
<Style.Triggers>

UserControl也是DependencyObject，同样有Style和ControlTemplate，触发器该怎么用就怎么用

<UserControl.Style> <Style> <Style.Triggers> </Style.Triggers> </Style> </UserControl.Style> <UserControl.Template> <ControlTemplate> <ControlTemplate.Triggers> </ControlTemplate.Triggers> </ControlTemplate> </UserControl.Template>

<UserControl.Resources>
<Storyboard x:Key="OnMouseEnter1">
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)" Storyboard.TargetName="userControl">
<EasingColorKeyFrame KeyTime="0" Value="Red"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
</UserControl.Resources>
<UserControl.Triggers>
<EventTrigger RoutedEvent="Mouse.MouseEnter">
<BeginStoryboard Storyboard="{StaticResource OnMouseEnter1}"/>
</EventTrigger>
</UserControl.Triggers>
