我们以定义一个TextBlock来鼠标移入/移出验证EventTrigger功能
xaml中内容如下:
<TextBlock Text="鼠标移动进来" Width="100" Height="50" Background="AliceBlue">
<TextBlock.Triggers>
<EventTrigger RoutedEvent="MouseEnter">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation To="300" Duration="0:0:1.5"
AccelerationRatio="0.10" DecelerationRatio="0.25"
Storyboard.TargetProperty="(Grid.Width)" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="MouseLeave">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="0:0:1.5"
AccelerationRatio="0.10" DecelerationRatio="0.25"
Storyboard.TargetProperty="(Grid.Width)" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</TextBlock.Triggers>
</TextBlock>
