1.在aspx页面中切换调用同一个SilverLight项目中的不同用户控件
1.1. 方法一
修改SilverLight项目启动文件App.xml的application_Startup事件
view sourcePRint?01 private void Application_Startup(object sender, StartupEventArgs e)
02
03 {
04
05 if (!e.InitParams.ContainsKey("InitPage"))
06
07 {
08
09 this.RootVisual = new MainPage();
10
11 return;
12
13 }
14
15 switch (e.InitParams["InitPage"])
16
17 {
18
19 case "SilverlightControl1":
20
21 this.RootVisual = new SilverlightControl1();
22
23 break;
24
25 case "SilverlightControl2":
26
27 this.RootVisual = new SilverlightControl2();
28
29 break;
30
31 default:
32
33 this.RootVisual = new MainPage();
34
35 break;
36
37 }
38
39
40
41 }
修改aspx页面
view sourceprint?01 <div id="silverlightControlHost">
02
03 <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%" >
04
05 <param name="source" value="ClientBin/Binglang.SilverlightDemo19.xap"/>
06
07 <param name="InitParams" value="InitPage=SilverlightControl1" />
08
09 <param name="onerror" value="onSilverlightError" />
10
11 <param name="background" value="white" />
12
13 <param name="minRuntimeVersion" value="3.0.40624.0" />
14
15 <param name="autoUpgrade" value="true" />
16
17 <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;">
18
19 <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="获取 Microsoft Silverlight" style="border-style: none"/>
20
21 </a>
22
23 </object><iframe id="_sl_historyFrame" style='visibility:hidden;height:0;width:0;border:0px'></iframe></div>
1.2. 方法二
修改SilverLight项目启动文件App.xml的Application_Startup事件
view sourceprint?01 private void Application_Startup(object sender, StartupEventArgs e)
02
03 {
04
05 if (!e.InitParams.ContainsKey("InitPage"))
06
07 {
08
09 this.RootVisual = new MainPage();
10
11 return;
12
13 }
14
15
16
17 Assembly assembly = Assembly.GetExecutingAssembly();
18
19 String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]);
20
21 UIElement rootVisual = assembly.CreateInstance(rootName) as UIElement;
22
23 this.RootVisual = rootVisual;
24
25
26
27 }
以上反射取得所需控件，也可以用下面反射代码：
view sourceprint?1 String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]);
view sourceprint?1 Type type = Type.GetType(rootName );
2 UIElement rootVisual = Activator.CreateInstance(type) as UIElement;
3
4 this.RootVisual = (UIElement)this._contentPage;
修改aspx页面
view sourceprint?01 <div id="silverlightControlHost">
02
03 <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%" >
04
05 <param name="source" value="ClientBin/Binglang.SilverlightDemo19.xap"/>
06
07 <param name="InitParams" value="InitPage=SilverlightControl1" />
08
09 <param name="onerror" value="onSilverlightError" />
10
11 <param name="background" value="white" />
12
13 <param name="minRuntimeVersion" value="3.0.40624.0" />
14
15 <param name="autoUpgrade" value="true" />
16
17 <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;">
18
19 <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="获取 Microsoft Silverlight" style="border-style: none"/>
20
21 </a>
22
23 </object><iframe id="_sl_historyFrame" style='visibility:hidden;height:0;width:0;border:0px'></iframe></div>
2.调用不同SilverLight项目中的指定控件
2.1.建立项目
(1)Binglang.SilverlightDemo20
(2)Binglang.SilverlightDemo20.Web
(3) Binglang.ExternalProject
注意：项目Binglang.SilverlightDemo20中需要引用using System.Xml.Linq;
假设(1)和(3)中各有一个控件，名称都为MainPage.xaml (不一定要相同)
