ChildWindow在Open时旋转出现

在App.xaml中：

<VisualState x:Name="Open">
　　<Storyboard>
　　　　<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot">
　　　　　　<EasingDoubleKeyFrame KeyTime="0" Value="90"/>
　　　　　　<EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/>
　　　　</DoubleAnimationUsingKeyFrames>
　　</Storyboard>
</VisualState>

其次，在<Grid x:Name="ContentRoot"...> 中加入：

<Grid.Projection><PlaneProjection/>
</Grid.Projection>

下面是两个窗口翻转出现的例子：A窗口在前为调用窗口，B窗口在后为被调用窗口。

A窗口在app.xaml中的样式：

                                <VisualStateGroup x:Name="AnimationStates"><VisualState x:Name="WindowShow"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState><VisualState x:Name="WindowHide"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="90"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState></VisualStateGroup>

B窗口在app.xaml中的样式：

                                <VisualStateGroup x:Name="WindowStates"><VisualState x:Name="Open"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0:0:0" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState><VisualState x:Name="Closed"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0:0:0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="90"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState></VisualStateGroup>

A窗口中某一个按钮的代码：

        private void button1_Click(object sender, RoutedEventArgs e){VisualStateManager.GoToState(this, "WindowHide", true);WinB w = new WinB();w.Show();w.Closed += new EventHandler(w_Closed);}void w_Closed(object sender, EventArgs e){VisualStateManager.GoToState(this, "WindowShow", true);}
