Call JS function in Silverlight4

1. In SL project, add reference assembly for "System.Windows.Browser"

 

2. In the HTML or Aspx page, which holds the silverlight control, create a JS function.

 

e.g. Open a window and with navigation URL

function TestFunc(str) { window.open(str); }

 

3. Call the JS function in Silverlight

HtmlPage.Window.CreateInstance("TestFunc", @"http://www.google.com");

 

Very simple :)
