Wpf动画背景颜色 [英] Wpf animate background color

问题描述

我需要帮助作出正确的决定。当一些事件发生时，我需要为我的用户控件的背景颜色设置动画。当它是，我想改变背景只有1秒，然后把它回来。我应该选择哪种方式？使用颜色动画或计时器，或者可以通过其他方式。

解决。谢谢大家！这对我有好处：

  ColorAnimation动画; 
 animation = new ColorAnimation（）; 
 animation.From = Colors.Orange; 
 animation.To = Colors.Gray; 
 animation.Duration = new Duration（TimeSpan.FromSeconds（1））; 
 this.elGrid.Background.BeginAnimation（SolidColorBrush.ColorProperty，animation）; 
  

解决方案

我会使用 EventTrigger c> c。

$ b 在此示例中，按钮Brackground 在 MouseLeave 事件上变为绿色。这个代码希望类似于你可能需要的。

 < Button Content =Button Height =75Horizo​​ntalAlignment =LeftMargin =27,12,0,0Name =btnImgBrushVerticalAlignment =TopWidth =160Background =LightGray> 
< Button.Triggers> 
< EventTrigger RoutedEvent =Button.MouseLeave> 
< BeginStoryboard> 
< Storyboard> 
< ColorAnimation To =Green
 Storyboard.TargetProperty =（Button.Background）。（SolidColorBrush.Color）
 FillBehavior =Stop
 Duration = ：0：1/> 
< / storyboard> 
< / BeginStoryboard> 
< / EventTrigger> 
< /Button.Triggers> 
< / Button> 
  

I need help in taking right decision. I need to animate a background color of my user control when some event happens. When it is, I want to change the background just for 1 second and then turn it back. Which way should I go? Use color animation or timer or may by some other way.

Solved. Thanks to all! This works good for me:

        ColorAnimation animation;
        animation = new ColorAnimation();
        animation.From = Colors.Orange;
        animation.To = Colors.Gray;
        animation.Duration = new Duration(TimeSpan.FromSeconds(1));
        this.elGrid.Background.BeginAnimation(SolidColorBrush.ColorProperty, animation);

解决方案

I would use an EventTrigger with a ColorAnimation.

In this example a Button Brackground goes green on a MouseLeave event. This code is hopefully similar to what you may need.

<Button Content="Button" Height="75" HorizontalAlignment="Left" Margin="27,12,0,0" Name="btnImgBrush" VerticalAlignment="Top" Width="160" Background="LightGray">
    <Button.Triggers>
        <EventTrigger RoutedEvent="Button.MouseLeave">
            <BeginStoryboard>
                <Storyboard>
                    <ColorAnimation To="Green" 
                                    Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)" 
                                    FillBehavior="Stop" 
                                    Duration="0:0:1"/>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Button.Triggers>
</Button>
