即使在设置后，WPF 故事板动画也会永远循环 [英] WPF Storyboard Animation Loops Forever Even After Being Set

问题描述

我有一个自定义用户控件，可根据绑定到 DataTrigger 的 DependencyProperty 设置动画.如果 DependencyProperty 等于 Failure，它应该为用户控件内的矩形(名为 buttonColor)的填充颜色设置动画.

I have a a custom user control to animate based on a DependencyProperty which is bound to a DataTrigger. If the DependencyProperty is equal to Failure, it should animate the fill color of a rectangle (named buttonColor) within the user control.

但出于某种原因，即使我将 RepeatBehavior 设置为包括 1 在内的任何值，它也会永远循环.

For some reason though, it always loops forever even if I set the RepeatBehavior to any value including 1.

如果我删除了 RepeatBehavior 属性，它只会播放一次动画(如预期).这是我遇到问题的代码:

If I remove the RepeatBehavior attribute, it only plays the animation once (as expected). Here is the code which I have the issue:

<DataTrigger Binding="{Binding Path=ButtonAction.Status}" Value="Failure">
    <DataTrigger.EnterActions>
        <StopStoryboard BeginStoryboardName="Pulse"/>

        <BeginStoryboard>
            <Storyboard RepeatBehavior="1">
                <ColorAnimation Storyboard.TargetName="buttonColor"
                                Storyboard.TargetProperty="Fill.Color" 
                                To="{StaticResource FailedColor}" 
                                AutoReverse="True" />
            </Storyboard>
        </BeginStoryboard>
    </DataTrigger.EnterActions>
</DataTrigger>

推荐答案

重复 N 次的正确语法是:

The correct syntax to repeat N times is:

<Storyboard RepeatBehavior="Nx">

例如:

<Storyboard RepeatBehavior="6x">
