Calling JS class methods from Silverlight application

I’m working on a project in which we have to call some JS method of the containing page from a Silverlight application.

It seems to be really straight forward like:


But this works only for global methods and not for JS class methods.

In fact this will not work:

You can make a global wrapper for every class methods but you can also do something like this:

private ScriptObject _jsObject = HtmlPage.Window.Eval("JsClassInstance") as ScriptObject;
private void UserControl_Loaded(object sender, RoutedEventArgs e)

that is far more elegant.

This is only a quick tip. Maybe I’ll write a more detailed post an JS-Silverlight interaction in the future.
