我一直在搜索，但是找不到很多，我想让我的任何动态标签页眉背景闪烁/闪烁，当我将它们称为Flash时。我找到了此解决方案，但我有点想绑定到wpf并触发它，所以我做不到。
我找到的解决方案是（Blink tab header on receiving event）。
我将在下面发送部分代码。

以及如何动态创建tabitems标头。

您刚刚在TabItem中添加了一个TabControl。将一个或多个项目添加到TabControl中，以查看样式中的IsMouseOver和IsSelected触发器。 TabControl中的单个项目已经被选中。您看不到视觉效果。

您的TabItem标头不只是Text。 Stackpanel将包含其他控件。 Soi将简单地为ContentControl.Opacity制作动画，如下所示。
<Style x:Key="FlashingHeader" TargetType="TabItem">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<!--Make The Header -->
<ContentControl x:Name="header" Content="{Binding}" />
<!--Make The Background Flash-->
<DataTemplate.Triggers>
<Trigger Property="Visibility" Value="Visible">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="header"
Storyboard.TargetProperty="(ContentControl.Opacity)"
From="1" To="0" Duration="0:0:1" AutoReverse="True" RepeatBehavior="Forever" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
