c# – WPF中的轻量级处理动画资源？

概述我创建了一个循环处理动画,类似于Chrome浏览器选项卡上看到的…我想在整个应用程序中使用它,因此决定将其作为资源..但是..我想知道什么是在我的应用程序中轻松使用此动画资源的最佳方式/练习…下面是我处理动画的xaml代码. 它应该用作DataTemplate还是ControlTemplate？ <Grid><Grid.Resources> <Storyboard x:Key="Loadin 我创建了一个循环处理动画,类似于Chrome浏览器选项卡上看到的…我想在整个应用程序中使用它,因此决定将其作为资源..但是..我想知道什么是在我的应用程序中轻松使用此动画资源的最佳方式/练习…下面是我处理动画的xaml代码.
它应该用作DataTemplate还是ControlTemplate？

解决方法 几天前我需要类似的东西.我将故事板和元素放在用户控件中进行动画处理.我添加了一个依赖属性,可以通过bIDing来启动/停止动画.剩下的就是在应用程序中的任何地方使用用户控件.

我的XAML看起来像这样：

<UserControl x:Class="MyAssembly.SpinningWait"   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"   xmlns:core="clr-namespace:MyAssembly">    <UserControl.Resources>        <Storyboard x:Key="canvasAnimation">            <DoubleAnimationUsingKeyFrames               RepeatBehavior="Forever"               Speedratio="24"               Storyboard.TargetProperty="(UIElement.Rendertransform).(transformGroup.Children)[0].(Rotatetransform.Angle)"               Storyboard.Targetname="canvas">                <discreteDoubleKeyFrame KeyTime="0:0:2" Value="45"/>                <discreteDoubleKeyFrame KeyTime="0:0:4" Value="90"/>                <discreteDoubleKeyFrame KeyTime="0:0:6" Value="135"/>                <discreteDoubleKeyFrame KeyTime="0:0:8" Value="180"/>                <discreteDoubleKeyFrame KeyTime="0:0:10" Value="225"/>                <discreteDoubleKeyFrame KeyTime="0:0:12" Value="270"/>                <discreteDoubleKeyFrame KeyTime="0:0:14" Value="315"/>                <discreteDoubleKeyFrame KeyTime="0:0:16" Value="360"/>            </DoubleAnimationUsingKeyFrames>        </Storyboard>    </UserControl.Resources>    <core:RadialPanel x:name="canvas" RendertransformOrigin="0.5,0.5">        <core:RadialPanel.Resources>            <Style targettype="Ellipse">                <Setter Property="Height" Value="6" />                <Setter Property="WIDth" Value="6" />                <Setter Property="Fill" Value="White" />            </Style>        </core:RadialPanel.Resources>        <core:RadialPanel.Rendertransform>            <transformGroup>                <Rotatetransform/>            </transformGroup>        </core:RadialPanel.Rendertransform>        <Ellipse />        <Ellipse Opacity="0.1" />        <Ellipse Opacity="0.2" />        <Ellipse Opacity="0.3" />        <Ellipse Opacity="0.4" />        <Ellipse Opacity="0.5" />        <Ellipse Opacity="0.6" />        <Ellipse Opacity="0.7" />    </core:RadialPanel></UserControl>

它的代码隐藏：

public partial class SpinningWait : UserControl{    private Storyboard _storyboard;    public SpinningWait()    {        InitializeComponent();    }    public bool IsWaiting    {        get { return (bool)GetValue(IsWaitingProperty); }        set { SetValue(IsWaitingProperty,value); }    }    public static Readonly DependencyProperty IsWaitingProperty =        DependencyProperty.Register("IsWaiting",typeof(bool),typeof(SpinningWait),new UIPropertyMetadata(false,new PropertyChangedCallback(OnIsWaitingChanged)));    private static voID OnIsWaitingChanged(DependencyObject d,DependencyPropertyChangedEventArgs e)    {        ((SpinningWait)d).OnIsWaitingChanged((object)d,e);    }    private voID OnIsWaitingChanged(object sender,DependencyPropertyChangedEventArgs e)    {        if (IsWaiting)        {            this.Visibility = Visibility.Visible;            this.StartAnimation();        }        else        {            this.Visibility = Visibility.Collapsed;            this.StopAnimation();        }    }    private voID StartAnimation()    {        this._storyboard = (Storyboard)FindResource("canvasAnimation");        this._storyboard.Begin(canvas,true);    }    private voID StopAnimation()    {        this._storyboard.Remove(canvas);    }}
