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
private void Application_Startup(object sender, StartupEventArgs e) { if (!e.InitParams.ContainsKey("InitPage")) { this.RootVisual = new MainPage(); return; } switch (e.InitParams["InitPage"]) { case "SilverlightControl1": this.RootVisual = new SilverlightControl1(); break; case "SilverlightControl2": this.RootVisual = new SilverlightControl2(); break; default: this.RootVisual = new MainPage(); break; } }
修改aspx页面
<div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%" > <param name="source" value="ClientBin/Binglang.SilverlightDemo19.xap"/> <param name="InitParams" value="InitPage=SilverlightControl1" /> <param name="onerror" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40624.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="获取 Microsoft Silverlight" style="border-style: none"/> </a> </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
private void Application_Startup(object sender, StartupEventArgs e) { if (!e.InitParams.ContainsKey("InitPage")) { this.RootVisual = new MainPage(); return; } Assembly assembly = Assembly.GetExecutingAssembly(); String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]); UIElement rootVisual = assembly.CreateInstance(rootName) as UIElement; this.RootVisual = rootVisual; }
以上反射取得所需控件,也可以用下面反射代码:
String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]);
Type type = Type.GetType(rootName ); UIElement rootVisual = Activator.CreateInstance(type) as UIElement; this.RootVisual = (UIElement)this._contentPage;
修改aspx页面
<div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%" > <param name="source" value="ClientBin/Binglang.SilverlightDemo19.xap"/> <param name="InitParams" value="InitPage=SilverlightControl1" /> <param name="onerror" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40624.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="获取 Microsoft Silverlight" style="border-style: none"/> </a> </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)
