使用Handy的PopupWindow来添加我们的动画功能好了。
1.首先要添加我们的放大和旋转属性在最外层的控件上
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform x:Name="PART_scale" />
<RotateTransform x:Name="PART_rot" />
</TransformGroup>
</Border.RenderTransform>
2.编写动画
<!--转出来-->
<Storyboard x:Key="showDW1">
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[1].Angle"
From="0" To="720" Duration="0:0:0.5" >
</DoubleAnimation>
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[0].ScaleX"
From="0" To="1" Duration="0:0:0.5"
AccelerationRatio="1">
</DoubleAnimation>
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[0].ScaleY"
From="0" To="1" Duration="0:0:0.5"
AccelerationRatio="1">
</DoubleAnimation>
</Storyboard>
3.可以在xaml界面直接触发
<EventTrigger SourceName="border" RoutedEvent="Window.Loaded">
<BeginStoryboard Storyboard="{StaticResource showDW1}">
</BeginStoryboard>
</EventTrigger>
4.这是在xaml上实现的，还可以用C#实现
//旋转出现
private void RotateAppear()
{
DoubleAnimation Ani = new DoubleAnimation()
{
From = 0,
To = 1,
Duration = new Duration(TimeSpan.FromSeconds(.5))
};
DoubleAnimation Rni = new DoubleAnimation()
{
From = 0,
To = 720,
Duration = new Duration(TimeSpan.FromSeconds(.5))
};
_scale.BeginAnimation(ScaleTransform.ScaleXProperty, Ani);
_scale.BeginAnimation(ScaleTransform.ScaleYProperty, Ani);
_rot.BeginAnimation(RotateTransform.AngleProperty, Rni);
}
在Loaded的时候调用就可以了。
5.你可以写好多套动画，根据需要展示即可。
6.好了，上源代码
xaml全部代码如下：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:controls="clr-namespace:Util.Controls"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/Util.Controls;component/Controls/FButton.xaml" /> </ResourceDictionary.MergedDictionaries> <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> <!--转出来--> <Storyboard x:Key="showDW1"> <DoubleAnimation Storyboard.TargetName="border"
