我有一个屏幕包含大约15-20个TextBlocks,每个TextBlocks绑定到一个不同的属性,起初所有TextBlocks都是空的文本更新来自其他客户端.

我想要做的是在文本更改时为闪烁文本设置动画3秒.

我使用下面的故事板来实现这一点:

    <Setter Property="Visibility" Value="Visible"/>

       <Style.Triggers>
        <EventTrigger RoutedEvent="UIElement.MouseEnter">  

            <BeginStoryboard >
                <Storyboard Duration="0:0:03">
                    <ObjectAnimationUsingKeyFrames BeginTime="00:00:00"  Storyboard.TargetProperty="(UIElement.Visibility)">
                        <DiscreteObjectKeyFrame KeyTime="00:00:00" Value="{x:Static Visibility.Visible}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:00.5" Value="{x:Static Visibility.Hidden}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:01" Value="{x:Static Visibility.Visible}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:01.5" Value="{x:Static Visibility.Hidden}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:02" Value="{x:Static Visibility.Visible}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:02.5" Value="{x:Static Visibility.Hidden}"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:03" Value="{x:Static Visibility.Visible}"/>
                    </ObjectAnimationUsingKeyFrames>
               </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Style.Triggers>
</Style>

使用鼠标输入事件文本闪存很好但使用Binding.TargetUpdated事件没有触发任何事情.

有人知道TextBlock文本更改时引发的事件吗？
