WPF Frame Management

I have a WPF application that contains a Frame control. The frame control displays html content. Is there a JavaScript function on the html page that I want to call after the html page is loaded into Frame and from WPF code? Is there a way that I can call the JavaScript method of the html page loaded into the WPF frame control and from the WPF code?

You cannot interact with HTML inside a frame. To interact with HTML, you can use WPF WebBrowser to control .NET 3.5 SP1.

You can see the action in this video in the WebBrowser control:
