How can I trigger JavaScript to execute after a Silverlight applet loads?

I am working on a project where I have a lot of interaction between JavaScript and managed code. In fact, I need the JS application to interface with the Silverlight application in the page right from the beginning. So I need the Silverlight application to load before the JS code gets executed.

But while doing so, most of the times I get the error that the开发者_开发技巧 object was not found as the Silverlight application has not yet been loaded. So I need the Silverlight to load before the JS executes.

Is there a way I can put a stop on the JS application until the Silverlight loads and then start executing?

First, you need to add an event handler to the Loaded event of your app, from that event handler you can call the javascript function like this:

using System.Windows.Browser;

namespace SilverlightApplication3
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(MainPage_Loaded);
        }
    void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        HtmlPage.Window.CreateInstance("SomeFunction", new string[] { "parameter1", "parameter2" });
    }
}

}

Note that you need the System.Windows.Browser namespace to use HtmlPage
