如何更改Silverlight加载屏幕的背景?

将新XAML文件添加到ASP.NET网站,其中Silverlight将显示。

<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel VerticalAlignment="Center">
<Grid>
<Rectangle x:Name="progressBarBackground" Fill="White" Stroke="Black"
StrokeThickness="1" Height="30" Width="200"></Rectangle>
<Rectangle x:Name="progressBar" Fill="Yellow" Height="28" Width="0">
</Rectangle>
</Grid>
<TextBlock x:Name="progressText" HorizontalAlignment="Center"
Text="0% downloaded ..."></TextBlock>
</StackPanel>
</Grid>   

接下来,您需要将JavaScript函数添加到HTML入口页或ASP.NET.

<script type="text/javascript">
function onSourceDownloadProgressChanged(sender, eventArgs)
{
sender.findName("progressText").Text =
Math.round((eventArgs.progress * 100)) + "% downloaded ...";
sender.findName("progressBar").Width =
eventArgs.progress * sender.findName("progressBarBackground").Width;
}
</script>   

要使用此初始屏幕,需要将splashscreensource参数添加到 连接JavaScript事件处理程序。如果你想在下载完成后做出反应,你可以 可以使用onsourcedownloadcomplete连接不同的JavaScript事件处理程序

<object data="data:application/x-silverlight," type="application/x-silverlight-2"
width="100%" height="100%">
<param name="source" value="ClientBin/SplashScreen.xap"/>
<param name="onerror" value="onSilverlightError" />
<param name="background" value="white" />
<param name="splashscreensource" value="SplashScreen.xaml" />
<param name="onsourcedownloadprogresschanged"
value="onSourceDownloadProgressChanged" />
...
</object>   

我希望这对你有帮助。
