我需要使WindowsFormsHost控件具有动画效果。问题是我看不到动画,窗口不刷新。如果我在动画过程中调整WPF窗口的大小,那么过渡是可见的。
我试着将WindowsFormsHost放在网格中,然后对网格进行动画处理,但结果是一样的。我把一些其他的东西放到网格中,以确保我正确地编写了动画。
下面是一些简单的应用程序来测试这一点:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Grid x:Key="MoveX">
<Grid.RenderTransform>
<TranslateTransform X="0"/>
</Grid.RenderTransform>
</Grid>
<Storyboard x:Key="Story">
<DoubleAnimation
Storyboard.Target="{StaticResource MoveX}"
Storyboard.TargetProperty="RenderTransform.(TranslateTransform.X)"
From="0"
To="600"/>
</Storyboard>
</Window.Resources>
<Grid>
<Grid.RenderTransform>
<TranslateTransform X="{Binding Source={StaticResource MoveX}, Path=RenderTransform.(TranslateTransform.X)}"/>
</Grid.RenderTransform>
<WindowsFormsHost Height="224" HorizontalAlignment="Left" Margin="26,24,0,0" Name="windowsFormsHost1" VerticalAlignment="Top" Width="404" Background="#FF762323">
<wf:Panel BackColor="Green" Width="300" Height="200"/>
</WindowsFormsHost>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="328,269,0,0" Name="button1" VerticalAlignment="Top" Width="75" >
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard Storyboard="{StaticResource Story}"/>
</EventTrigger>
</Button.Triggers>
</Button>
<Label Content="Label" Height="28" HorizontalAlignment="Left" Margin="85,269,0,0" Name="label1" VerticalAlignment="Top" />
</Grid>
</Window>有什么办法可以解决这个问题吗?

在混合WPF和WinForms或ActiveX内容时,这是一个众所周知的问题。在内部,每个渲染引擎都有自己的空域,不可能像动画那样正确地进行互操作。
随着.net 4.5版本的发布,这个问题应该会得到解决。
