Take a screenshot of a webpage (with Silverlight controls)

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

Currently, the System.Windows.Forms.WebBrowser control is used to take screenshots.

Forms.WebBrowser works great when I take a screenshot for regular pages. However, for pages with Silverlight controls, it does not work.

My code for taking screenshots 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 rendered in the WebBrowser control
            bitmap = new Bitmap(webBrowser.Width, webBrowser.Height);
            webBrowser.DrawToBitmap(bitmap, new Rectangle(0, 0, webBrowser.Width, webBrowser.Height));

}

    if (System.IO.Directory.Exists(myPicsPath))
    {
      Rectangle bounds = yourBrowser.Bounds;
      using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
      {
        using (Graphics g = Graphics.FromImage(bitmap))
        {
          g.CopyFromScreen(new Point(bounds.Left, bounds.Top), Point.Empty, bounds.Size);
        }
        bitmap.Save(myPicsPath + System.IO.Path.GetRandomFileName() + ".png", System.Drawing.Imaging.ImageFormat.Png);
      }
    }
    else
    {
      System.IO.Directory.CreateDirectory(myPicsPath);
      MessageBox.Show("Screenshot directory created in " + Environment.GetFolderPath(Environment.SpecialFolder.MyPictures) + @"\" + " named SchreenshotFolder\nScreenshot is not saved. Hit button again to save it.");
    }
