我有这个代码(到目前为止它正在工作);
<Image Name="img_person" Tag="{Binding Path=MyProperty1, NotifyOnTargetUpdated=True}" Canvas.Top="0" Canvas.Left="0">
<Image.Triggers>
<EventTrigger RoutedEvent="Binding.TargetUpdated">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="img_person"
Storyboard.TargetProperty="(Canvas.Top)"
By="64"
Duration="0:0:0.8"
AutoReverse="False" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Image.Triggers>
我想改变这条线;
<EventTrigger RoutedEvent="Binding.TargetUpdated">
对于这样的事情;
<EventTrigger ThisParticularPropertyHasChanged="MyProperty1">
我想这样做,因为我将有几个情节提要,每个情节提要在特定属性更改时启动。有了 1 个属性,我一直将它绑定到图像的 Tag 属性,但现在我有几个要做(大约 8 个)我不知道该怎么做。
该类实现 INotifyPropertyChanged。
谢谢。
解决方案,感谢 sa_ddam213;
