电子 我在下面的链接中收到了一个很好的答案,我需要对此进行编码,因为我没有设置椭圆数的设置值。我很难将它转换为c#并希望得到一些帮助。答案是Start storyboard on a different control on a trigger in WPF。
代码:
<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>
答案 0 :(得分:3)
这样的事情:
var style = new Style(typeof(Ellipse));
var trigger = new DataTrigger();
trigger.Binding = new Binding("Opacity") { ElementName = "ellipse1" };
trigger.Value = 0.5;
Storyboard sb = new Storyboard();
//Add animation to sb, note the attached storyboard properties which are set with static methods:
//Storyboard.SetTarget(...);
//Storyboard.SetTargetProperty(...);
//Storyboard.SetTargetName(...);
trigger.EnterActions.Add(new BeginStoryboard() { Storyboard = sb });
style.Triggers.Add(trigger);
