如果在ellipse1上运行一个故事板动画来改变不透明度,我可以在其不透明度上触发某个值并在ellipse2上启动一个故事板动画,它将开始淡入吗?
<UniformGrid Columns="2">
<Ellipse Width="25" Height="25" Name="ellipse1">
<Ellipse.Triggers>
<Trigger Property="Opacity" Value=".7">
do something here to start a opacity fade in on ellipse2
</Trigger>
</Ellipse.Triggers>
</Ellipse>
<Ellipse Width="25" Height="25" Name="ellipse2">
</Ellipse>
</UniformGrid>

您可以在ellipse2中使用DataTrigger
来观察ellipse1:
<Ellipse Width="25" Height="25" Name="ellipse2">
<Ellipse.Style>
<Style TargetType="{x:Type Ellipse}">
<Style.Triggers>
<DataTrigger Binding="{Binding Opacity, ElementName=ellipse1}" Value="0.5">
<DataTrigger.EnterActions>
<BeginStoryboard>
<!-- Storyboard for ellipse 2 here -->
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Style.Triggers>
</Style>
</Ellipse.Style>
</Ellipse>
