WPF动画自定义控件中的问题 [英] Problem in WPF Animation Custom Control

问题描述

我的应用程序有一个自定义用户控件（带动画的椭圆。）在我的主窗口中，我同时使用usercontrol和一个按钮

控制图像

我需要在按下按钮时为控件设置动画：

My app has a custom user control (an ellipse with animation.) In my main window, I use both the usercontrol and a button
Image of the Control
I need to animate the control when the button is pressed:

private void button1_Click(object sender, RoutedEventArgs e)
    {
        for (int i = 0; i < 10; i++)
        {
            userControl11.BlueAnimate();
            dowork1();
            userControl11.RedAnimate();
            dowork2();
        }
    }

我的xml控件中的
我有以下定义：

in my xml of the control i have the following definition:

<UserControl.Resources>
    <Storyboard x:Name="Ellipse1Animation" x:Key="Ellipse1Animation">
        <DoubleAnimation

            x:Name="AnimacionEllipse"

            Storyboard.TargetName="_Ellipse"

            Storyboard.TargetProperty="Opacity"

            From="0.0" To="1.0" Duration="0:0:1"

            AutoReverse ="True"

            RepeatBehavior="Forever"

            />
    </Storyboard>
</UserControl.Resources>

userControl11.BlueAnimate（）;具有以下代码（对于其他方法几乎相同;唯一的变化是偏色。）

The userControl11.BlueAnimate(); has the following code (It is almost the same for the other method; the only change is the color cast.)

Public Sub BlueAnimate()
       Dim AnimJob As Action = Function()
              Dispatcher.Invoke(DirectCast(
                         Function()
                         Dim sb As Storyboard = FindResource("Ellipse1Animation")
                         Dim Anim As DoubleAnimation = sb.Children(0)
                         _Ellipse.Fill = Brushes.Blue
                         Storyboard.SetTargetName(Anim, "_Ellipse")
                         sb.Beging()
              End Function, Action))
              End Function
       Task.Factory.StartNew(AnimJob )
   End Sub

当我投射userControl11.BlueAnimate时，它不会改变。可视界面保持冻结状态，不起作用。有人可以帮忙吗？



感谢您的时间。

When I cast the userControl11.BlueAnimate, it doesn't change. The visual interface stays frozen and doesn't work. Can someone help?

Thanks for your time.
