Customize and call the Silverlight Control

1. Switch to call different user controls in the same Silverlight project on the ASPX page

 

1.1. method 1

Modify the application_startup event of the Silverlight project Startup File app. xml

 

 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;            }         }

Modify the ASPX page

 

 

<Div id = "silverlightcontrolhost"> <Object Data = "data: Applications/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 =" minruntime Version "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; ">  </a> </Object> <IFRAME id =" _ sl_historyframe "style = 'visibility: hidden; Height: 0; width: 0; Border: 0px '> </iframe> </div>

 

1.2. method 2

 

 

Modify the application_startup event of the Silverlight project Startup File app. xml

 

  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;         }

You can use the following reflection code to obtain the required control:

 

 

 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;

 

Modify the ASPX page

 

<Div id = "silverlightcontrolhost"> <Object Data = "data: Applications/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 =" minruntime Version "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; ">  </a> </Object> <IFRAME id =" _ sl_historyframe "style = 'visibility: hidden; Height: 0; width: 0; Border: 0px '> </iframe> </div>

2. Call the specified control in different Silverlight Projects 

 

2. 1. Create a project

(1) binglang. silverlightdemo20

(2) binglang. silverlightdemow.web

(3) binglang. externalproject

 

Note: using system. xml. LINQ must be referenced in the binglang. silverlightdemo20 project;

 

Assume that (1) and (3) each have a control named mainpage. XAML (not necessarily the same)
