Screen capturing a WPF form

In this article I explained how a form with a DocumentViewer control can be used to render, save, and print official documents - like contracts and registration forms. I'm using that same form now behind a Print Screen button or command, accessible from the application's main toolbar. It allows the user to generate a screenshot of the application's main window. Here's what you can type in the button_clicked or the command_executed code:

        /// <summary>

        /// Opens a ReportWindow with a screenshot of the whole main window and its contents.

        /// </summary>

        /// <param name="sender">The (toolbar) button that was clicked.</param>

        /// <param name="e">The Event Args.</param>

        private void PrintScreenButton_Click(object sender, RoutedEventArgs e)

        {

            XpsWysiwyg reportWindow = new XpsWysiwyg();

            reportWindow.Title = "Schermafdruk"; // That's just Dutch for 'ScreenShot' ;-)

            reportWindow.WindowState = WindowState.Normal;

            reportWindow.ElementToRender = this; // The Main Window

            reportWindow.documentViewer1.FitToMaxPagesAcross(1); // Zoom to whole Page

            reportWindow.ShowDialog();

        }

Here's how it looks like in a real application:
