如何在故事板完成后调用一个方法
本文关键字:方法 一个 调用 故事 | 更新日期: 2023-09-27 18:07:56
我写了下面的代码:
public void name(object sender, RoutedEventArgs e)
{
DoubleAnimation myDoubleAnimation = new DoubleAnimation();
myDoubleAnimation.From = 1.0;
myDoubleAnimation.To = 0.0;
myDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.2));
sb1 = new Storyboard();
sb1.Children.Add(myDoubleAnimation);
Storyboard.SetTargetName(myDoubleAnimation, one.Name);
Storyboard.SetTargetProperty(myDoubleAnimation, new PropertyPath(Grid.OpacityProperty));
sb1.Begin(this);
if (one.Opacity == 0)
{
Container_one.Children.Remove(one);
}
}
,但它不能正常工作。动画工作正常,但删除是错误的。我如何将Storyboard-End与方法的调用结合起来?
由于Storyboard的执行是异步的,您需要添加一个"Storyboard Completed"事件处理程序:
story.Completed += new EventHandler(Story_Completed);
然后把你的Remove代码放在里面:
private void Story_Completed(object sender, EventArgs e)
{
if (one.Opacity == 0)
{
Container_one.Children.Remove(one);
}
}
将在Storyboard完成时执行
