从C＃触发故事板？ [英] Trigger a Storyboard from C#?

问题描述

我在< Window.Resources>中有一个故事板。在XAML中声明并从声明的路由事件中很好地触发。

如何从C＃开始讨论故事板？
我正在与FindResource（）和要获取的资源的密钥名称搏斗对故事板的引用，但不是成功。

非常感谢任何工作代码的链接或片段。

I have a storyboard in <Window.Resources> declared in XAML and triggering nicely from a declared routed event.

How do I begin hte storyboard from C#?
I'm wrestling with FindResource() and the key name of the resource to get a reference to the storyboard, but not with success.

Any links or snippets to working code will be greatly appreciated.

 

谢谢。

推荐答案

在这里，请记住这没有错误检查，不应该按原样使用： ）

XAML：

Here you go, but please remember this has no error checking, and should not be used as is :)

XAML:

<Window
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	x:Class="WpfApplication1.MainWindow"
	x:Name="Window"
	Title="MainWindow"
	Width="640" Height="480">
	<Window.Resources>
		<Storyboard x:Key="Storyboard1">
			<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="button" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)">
				<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"/>
				<SplineDoubleKeyFrame KeyTime="00:00:01.9000000" Value="173"/>
			</DoubleAnimationUsingKeyFrames>
			<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="button" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)">

				<SplineDoubleKeyFrame KeyTime="00:00:01.9000000" Value="140"/>
			</DoubleAnimationUsingKeyFrames>
		</Storyboard>
	</Window.Resources>
	<Window.Triggers>
		<EventTrigger RoutedEvent="FrameworkElement.Loaded">
			<BeginStoryboard Storyboard="{StaticResource Storyboard1}"/>
		</EventTrigger>
	</Window.Triggers>

	<Grid x:Name="LayoutRoot">
		<Button x:Name="button" HorizontalAlignment="Left" Margin="84,76,0,0" VerticalAlignment="Top" Width="76" Height="39" Content="Button" RenderTransformOrigin="0.5,0.5">
			<Button.RenderTransform>
				<TransformGroup>
					<ScaleTransform/>
					<SkewTransform/>
					<RotateTransform/>
					<TranslateTransform/>
				</TransformGroup>
			</Button.RenderTransform>
		</Button>
	</Grid>
</Window>
