Silverlight加載界面的實(shí)現(xiàn)方法在這篇文章中將會(huì)為大家詳細(xì)介紹。希望對(duì)一些又需要的朋友men有些幫助。在一個(gè)解決方案中，有SplashScreenSourceweb和SplashScreenSource兩個(gè)項(xiàng)目。#t#

要往silverlight中加入自定義裝載界面，需要加入到SplashScreenSourceweb項(xiàng)目中，這樣，自定義裝載界面就不會(huì)和其它xaml文件一起打包到silverlight程序包中。

Silverlight加載界面步驟如下：

1.右擊silverlightapplicationweb項(xiàng)目，選擇屬性，選擇啟動(dòng)選項(xiàng)，把SplashScreenSourceTestPage.html設(shè)為啟動(dòng)頁(yè)面。

2.右擊silverlightapplicationweb項(xiàng)目，選擇添加新項(xiàng)，選擇添加一個(gè)Silverlight JScript 頁(yè)，命名為SplashScreen.xaml。

3.打開(kāi)SplashScreen.xaml，換成如下代碼：

Silverlight加載界面4.打開(kāi)SplashScreenSourceTestPage.html，把代碼

< param name="source" 
value="ClientBin/Splash
ScreenSource.xap"/> 

改成

< param name="source" 
value="SplashScreenSource.xap"/>  

5.在解決方案資源管理器中，把ClientBin目錄下的SplashScreenSource.xap拖到SplashScreenSourceWeb根目錄下。

6.打開(kāi)SplashScreenSourceTestPage.html，加入如下代碼：

< param name="splashscreensource" 
value="SplashScreen.xaml"/> 
< param name="onSourceDownload
ProgressChanged" value=
"onSourceDownloadProgressChanged" /> 

Silverlight加載界面7.打開(kāi)SplashScreen.js，輸入以下代碼：

function onSourceDownload
ProgressChanged(sender, eventArgs)  
{  
sender.findName("uxStatus").
Text = "Loading: " + Math.
round((eventArgs.progress * 
1000)) / 10 + "%";  
sender.findName("uxProgressBar").
ScaleY = eventArgs.progress * 356;  
} 

8.打開(kāi)SplashScreenSourceTestPage.html，加入以下代碼：

< script type="text/javascript" 
src="splashscreen.js">< /script> 

9.運(yùn)行Silverlight加載界面！
