load silverlight controls in asp.net page

问题

I have a silverlight project which contains 2 silverlight controls Control_1 and Control_2. Please note that its in same app.Now I have asp.net project which will use any of these silverlight control (either Control_1 or Control_2).

Challenge is how do I tell silverlight which control to load. I used param property in html object to pass the parameters and tell the app which control to load at runtime?

But what if there are more than 2 controls in same project? We cannot have a long switch case statement in the app file only to load the controls. Is there any better way?

No, There isn't, and this is not about Silverlight itself, this is normal logic.

In your App.xaml file, put this:

using System.Windows; // Application, StartupEventArgs

namespace SilverlightApplication
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();
        }

        private void Application_Startup(object sender, StartupEventArgs e)
        {
            // Specify the main application UI
            if(SomeCondition == true)
                this.RootVisual = new Control1();
            else
                this.RootVisual = new Control2();

            // In the same way, you may define a switch statment
        }
    }
}

You may decide what that condition is by passing parameters to the XAP file, and finally you access those by accessing e.InitParams in Application_Startup

For more info: Application.RootVisual
