[英]C#/WPF Handling active Storyboard Animations when spamming the 'Toggle'
[英]C# WPF: Toggle Margin value using Storyboard and EventTrigger
所以我有这个 WPF 代码:
<EventTrigger RoutedEvent="PreviewMouseRightButtonDown">
<EventTrigger.Actions>
<BeginStoryboard Name="Storyboard">
<Storyboard>
<ThicknessAnimation Storyboard.TargetProperty="Margin">
...
</ThicknessAnimation>
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
有没有办法将底部边距从一个值切换到另一个值,例如:
Margin = Margin.Bottom is 0 ? new Thickness(0, 0, 0, -50) : new Thickness(0);
编码复制在这里
namespace SDKSamples
{
public class ThicknessAnimationExample : Page
{
public ThicknessAnimationExample()
{
// Create a NameScope for this page so that
// Storyboards can be used.
NameScope.SetNameScope(this, new NameScope());
// Create a Border which will be the target of the animation.
Border myBorder = new Border();
myBorder.Background = Brushes.Gray;
myBorder.BorderBrush = Brushes.Black;
myBorder.BorderThickness = new Thickness(1);
myBorder.Margin = new Thickness(0, 60, 0, 20);
myBorder.Padding = new Thickness(20);
// Assign the border a name so that
// it can be targeted by a Storyboard.
this.RegisterName( "myAnimatedBorder", myBorder);
ThicknessAnimation myThicknessAnimation = new ThicknessAnimation();
myThicknessAnimation.Duration = TimeSpan.FromSeconds(1.5);
myThicknessAnimation.FillBehavior = FillBehavior.HoldEnd;
// Set the From and To properties of the animation.
// BorderThickness animates from left=1, right=1, top=1, and bottom=1
// to left=28, right=28, top=14, and bottom=14 over one and a half seconds.
myThicknessAnimation.From = new Thickness(1, 1, 1, 1);
myThicknessAnimation.To = new Thickness(28, 14, 28, 14);
// Set the animation to target the Size property
// of the object named "myArcSegment."
Storyboard.SetTargetName(myThicknessAnimation, "myAnimatedBorder");
Storyboard.SetTargetProperty(
myThicknessAnimation, new PropertyPath(Border.BorderThicknessProperty));
// Create a storyboard to apply the animation.
Storyboard ellipseStoryboard = new Storyboard();
ellipseStoryboard.Children.Add(myThicknessAnimation);
// Start the storyboard when the Path loads.
myBorder.Loaded += delegate(object sender, RoutedEventArgs e)
{
ellipseStoryboard.Begin(this);
};
StackPanel myStackPanel = new StackPanel();
myStackPanel.HorizontalAlignment = HorizontalAlignment.Center;
myStackPanel.Children.Add(myBorder);
Content = myStackPanel;
}
}
}
