Taking Screenshot of Web Page (with Silverlight Controls) Programatically

Question

I have a web page that displays some silver light controls. I need to take screenshot of this web page programmatically.

Currently using the System.Windows.Forms.WebBrowser control for taking screenshot.

Forms.WebBrowser works fine when I take screenshot for normal pages. However for the pages with Silverlight controls it does not work.

My code for taking screenshot is as follows: Bitmap bitmap = null; using (WebBrowser webBrowser = new WebBrowser()) { webBrowser.ScrollBarsEnabled = false; webBrowser.ScriptErrorsSuppressed = true;

            // Set the size of the WebBrowser control
            webBrowser.Width = width;
            webBrowser.Height = height;

            // Load the webpage into a WebBrowser control
            webBrowser.Navigate(url);
            while (webBrowser.ReadyState != WebBrowserReadyState.Complete)
            {
                Application.DoEvents();
            }

            if (width == -1)
            {
                // Take Screenshot of the web pages full width
                webBrowser.Width = webBrowser.Document.Body.ScrollRectangle.Width;
            }

            if (height == -1)
            {
                // Take Screenshot of the web pages full height
                webBrowser.Height = webBrowser.Document.Body.ScrollRectangle.Height;

            }

            // Get a Bitmap representation of the webpage as it's rendered in the WebBrowser control
            bitmap = new Bitmap(webBrowser.Width, webBrowser.Height);
            webBrowser.DrawToBitmap(bitmap, new Rectangle(0, 0, webBrowser.Width, webBrowser.Height));

}
