Question

我们有一个 UWP项目，目标是 Windows 10周年纪念版（10.0; Build 14393）。

我们在Code-Behind中触发了 Storyboard 。它以前工作;在我们定位Win 10周年纪念版之前。

但现在，每次调用 StoryBoard.Begin 时，它都会突然崩溃App。

以下是XAML：

<Grid.RenderTransform>
    <CompositeTransform />
</Grid.RenderTransform>
<Grid.Resources>
    <Storyboard x:Name="MoveX">
        <DoubleAnimation Duration="0:0:0.15" Storyboard.TargetName="Grid_TemplateRoot" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" To="-520">
            <DoubleAnimation.EasingFunction>
                <ElasticEase EasingMode="EaseOut" Oscillations="0" Springiness="1" />
            </DoubleAnimation.EasingFunction>
        </DoubleAnimation>
    </Storyboard>
</Grid.Resources>

以下是代码隐藏：

var storyBoard = senderGrid.Resources["MoveX"] as Storyboard;
storyBoard.Completed += (s, o) => MoveX_Completed(item, deleteElementRef);
storyBoard.Begin();

其他人有经验并解决了这个问题吗？

编辑：这是MoveX_Completed方法：

    private void MoveX_Completed(CompositeTransform item, Canvas deleteElementRef)
{
    try
    {
        item.TranslateX = 0;
        if (deleteElementRef.Visibility == Visibility.Visible)
        {
            deleteElementRef.Visibility = Visibility.Collapsed;
            deleteElementRef.Background = new SolidColorBrush(Colors.Transparent);
        }

        var type = deleteElementRef.DataContext.GetType().Name;

        if (type == "CheckItemViewModel")
        {
            var vm = deleteElementRef.DataContext as CheckItemViewModel;

            if (vm != null)
                vm.RemoveOrVoidFromCheckCommand.Execute(null);
        }
        else if (type == "CheckExtensionDataItemViewModel")
        {
            var vm = deleteElementRef.DataContext as CheckExtensionDataItemViewModel;

            if (vm != null)
                vm.RemoveOrVoidFromCheckCommand.Execute(null);
        }
    }
    catch (Exception ex)
    {
        POSEventSource.Log.Warn("Error while swiping to delete check item, MoveX_Completed: " + ex.Message);
    }
}

似乎这是一个已知的错误。它与振荡设置为0有关。

解决方法是使用ExponentialEase。
