  private void Button_Click_2(object sender, RoutedEventArgs e)
   
        	//获取当前窗口所有控件
            var grid = (DependencyObject)this.Content;
            List<DependencyObject> list = new List<DependencyObject>();
            Action<DependencyObject> action = null;
            action = (a) =>
            
                var count = VisualTreeHelper.GetChildrenCount(a);
                for (int i = 0; i < count; i++)
                
                    var elem = VisualTreeHelper.GetChild(a, i);
                    list.Add(elem);
                    action(elem);
                
            ;

            action(grid);

			//遍历控件，设置相关属性
            foreach (var item in list)
            
                if (item is TextBox)
                
                    (item as TextBox).IsEnabled = false; //批量设置输入框禁用
                
                else if (item is ComboBox)
                
                    (item as ComboBox).IsEnabled = false;
