This is the code to open a popup window in SilverLight.

To open a website in a popup using SilverLight, we need to call Window.Navigate method. This method can be used in two different ways i.e. simply navigating to that webpage or using the window option [_blank, _self] etc.

// Navigate to the webpage itself
System.Windows.Browser.HtmlPage.Window.Navigate(new Uri(”http://www.microsoft.com”));

//or if you want to open a popup (in a separate window)
System.Windows.Browser.HtmlPage.Window.Navigate(new Uri(”http://www.microsoft.com”), “_blank”);
