Silverlight 自定义加载页面

xaml代码行:

1.<Canvas   
2.        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"       
3.        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
4.        x:Name="parentCanvas"        
5.         Width="1262" Height="613" Background="Black"  
6.        >  
7.    <Canvas.Triggers>  
8.      <EventTrigger RoutedEvent="Canvas.Loaded">  
9.        <BeginStoryboard>  
10.  
11.          <Storyboard x:Name="CycleAnimation" RepeatBehavior="Forever">  
12.      <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="snake" Storyboard.TargetProperty="Angle">  
13.        <SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"></SplineDoubleKeyFrame>  
14.        <SplineDoubleKeyFrame KeyTime="00:00:02" Value="10"></SplineDoubleKeyFrame>  
15.        <SplineDoubleKeyFrame KeyTime="00:00:04" Value="0"></SplineDoubleKeyFrame>  
16.        <SplineDoubleKeyFrame KeyTime="00:00:06" Value="-10"></SplineDoubleKeyFrame>  
17.        <SplineDoubleKeyFrame KeyTime="00:00:08" Value="0"></SplineDoubleKeyFrame>  
18.      </DoubleAnimationUsingKeyFrames>  
19.    </Storyboard>  
20.        </BeginStoryboard>  
21.      </EventTrigger>  
22.    </Canvas.Triggers>  
23.  <Grid Width="1262" Height="613">  
24.    <Grid Width="120" Height="98" VerticalAlignment="Center" HorizontalAlignment="Center" RenderTransformOrigin="0.5,0" x:Name="pb1">  
25.      <Grid.Background>  
26.        <ImageBrush ImageSource="/loading/ss.png"></ImageBrush>  
27.      </Grid.Background>  
28.      <Grid.RenderTransform>  
29.        <TransformGroup>  
30.          <ScaleTransform/>  
31.          <SkewTransform/>  
32.          <RotateTransform Angle="0" x:Name="snake"/>  
33.          <TranslateTransform/>  
34.        </TransformGroup>  
35.      </Grid.RenderTransform>  
36.      <TextBlock x:Name="txtLoad" Text="0%" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="22" Margin="0 30 0 0" Foreground="White"></TextBlock>  
37.    </Grid>  
38.  </Grid>  
39.</Canvas>  

js代码行:

1.function onSourceDownloadProgressChanged(sender, eventArgs) {  
2.    sender.findName("txtLoad").Text = "" + Math.round((eventArgs.progress * 1000)) / 10 + "%";  
3.}  

 function onSourceDownloadProgressChanged(sender, eventArgs) {
     sender.findName("txtLoad").Text = "" + Math.round((eventArgs.progress * 1000)) / 10 + "%";
 }

在aspx引用silverlight的object中加入

<param name="splashscreensource" value="Loading/CustomLoadPage.xaml"/> <param name="onSourceDownloadProgressChanged" value="onSourceDownloadProgressChanged" />

并引用上面的js文件

js文件的主要作用是显示载入的百分比.

silverlight的初始化屏幕.微软说明地址:http://msdn.microsoft.com/zh-cn/library/cc838130(VS.95).aspx

关于循环动画的事件触发器:http://msdn.microsoft.com/zh-cn/library/bb979699(VS.95).aspx

<EventTrigger RoutedEvent="Canvas.Loaded">的意思就是当这个画布被加载后.所执行的事件.

这样就可以在这个中间写入我们需要显示的效果.不需要用js来调用storybroder的启动.
