故事板完成后如何调用方法? [英] How to call a method after a Storyboard finished?
本文介绍了故事板完成后如何调用方法?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我写了以下代码:
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);
}
}
但它不正确.动画工作正常,但删除是错误的.如何将 Storyboard-End 与对方法的调用结合起来?
but it doesn't wwork correct. The Animation works fine, but the Remove is wrong. How can i combine a Storyboard-End with the call to a methode?
非常感谢.
推荐答案
由于 Storyboard 的执行是异步的,因此您需要添加一个Storyboard Completed"事件处理程序:
As the execution of the Storyboard is asynchronous you need to add a "Storyboard Completed" event handler:
story.Completed += new EventHandler(Story_Completed);
然后将您的删除代码放入其中:
then put your Remove code in that:
private void Story_Completed(object sender, EventArgs e)
{
if (one.Opacity == 0)
{
Container_one.Children.Remove(one);
}
}
这将在 Storyboard 完成时执行.
This will get executed when the Storyboard completes.
