        {
            StackPanel sp = this.Content as StackPanel;
            UIElementCollection children = sp.Children;
            foreach (UIElement ui in children)
            {
                if (ui is CheckBox)
                {
                    CheckBox cb = ui as CheckBox;
                    if (cb.IsChecked == true)
                    {
                        MessageBox.Show(cb.Content.ToString());
                    }
                }
