Silverlight 3 - Out of browser HtmlPage.Window.Navigate - silverlight

Question

Silverlight 3 allows you to run your application out of the browser, which installs a link on your desktop/start menu.
The problem is we are currently using
System.Windows.Browser.HtmlPage.
Window.Navigate(new Uri("http://<server>/<resource>"), "_blank")
to load a URL into a new browser window (it's to provide a 'print friendly' page for users to print). This works in the normal SL in-browser version, but outside the browser we get 'The DOM/scripting bridge is disabled.' exception thrown when issuing the call.
Is there an alternative which works out of the browser?
I've seen Open page in silverlight out of browser but I need to do this entirely in code, so I don't want to add a (hidden) hyperlink button and then programmatically 'click' it (unless I absolutely have to...).

Answer 1

you can try inheriting from HyperlinkButton and exposing public Click() method (which you can then instantiate and call from code instead of declaring it in xaml).

Answer 2

I wrote an Extension method based on the idea to inherit from the HyperlinkButton.
public static class UriExtensions {
class Clicker : HyperlinkButton {
public void DoClick() {
base.OnClick();
}
}
static readonly Clicker clicker = new Clicker();
public static void Navigate(this Uri uri) {
Navigate(uri, "_self");
}
public static void Navigate(this Uri uri, string targetName) {
clicker.NavigateUri = uri;
clicker.TargetName = targetName;
clicker.DoClick();
}
}
Then use can use it simple, like
new Uri("http://www.google.com").Navigate("_blank");
