WPF 触发器（根据属性使用动画）

1.是按钮的边框有闪烁的效果，是根据属性来设置的而非一般的事件

 1  <Style x:Key="PipesButtonStyle" TargetType="Button">
 2             <Setter Property="Height" Value="25"/>
 3             <Setter Property="IsHitTestVisible" Value="False"/>
 4             <Setter Property="Background" Value="Transparent"/>
 5             <Setter Property="Template">
 6                 <Setter.Value>
 7                     <ControlTemplate TargetType="{x:Type Button}">
 8                         <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" BorderBrush="Transparent" Background="{TemplateBinding Background}" RenderPressed="{TemplateBinding IsPressed}" RenderDefaulted="{TemplateBinding IsDefaulted}" SnapsToDevicePixels="true"/>
 9                     </ControlTemplate>
10                 </Setter.Value>
11             </Setter>
12             <Setter Property="Effect">
13                 <Setter.Value>
14                     <DropShadowEffect x:Name="effect" BlurRadius="0" Color="Red" Direction="0"
15                                       Opacity="0" RenderingBias="Performance" ShadowDepth="0"/>
16                 </Setter.Value>
17             </Setter>
18             <Style.Triggers>
19                 <Trigger Property="IsHitTestVisible" Value="true">
20                     <Trigger.EnterActions>
21                         <BeginStoryboard x:Name="enterStory">
22                             <Storyboard>
23                                 <DoubleAnimation Storyboard.TargetProperty="(FrameworkElement.Effect).(DropShadowEffect.BlurRadius)"
24                                                  BeginTime="00:00:00" Duration="00:00:01"
25                                                  From="0" To="10" 
26                                                  AutoReverse="True" RepeatBehavior="Forever">
27                                 </DoubleAnimation>
28                                 <DoubleAnimation Storyboard.TargetProperty="(FrameworkElement.Effect).(DropShadowEffect.Opacity)"
29                                                  BeginTime="00:00:00" Duration="00:00:00"
30                                                  From="0" To="1" >
31                                 </DoubleAnimation>
32                             </Storyboard>
33                         </BeginStoryboard>
34                     </Trigger.EnterActions>
35                     <Trigger.ExitActions>
36                         <StopStoryboard BeginStoryboardName="enterStory">
37                         </StopStoryboard>
38                     </Trigger.ExitActions>
39                 </Trigger>
40             </Style.Triggers>
41         </Style>

2.遇到问题：如果我要感觉Content的值来设置Content的值是不行的，会报错。（错误原因为止，有待商榷）
