public void NotConditionExample(AutomationElement elementMainWindow)
{
    if (elementMainWindow == null)
    {
        throw new ArgumentException();
    }

    // Set up a condition that finds all buttons and radio buttons.
    OrCondition conditionButtons = new OrCondition(
        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button),
        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.RadioButton));

    // Use NotCondition to retrieve elements that are not buttons or radio buttons.
    Condition conditionNotButtons = new NotCondition(conditionButtons);
    AutomationElementCollection elementCollectionNotButtons = elementMainWindow.FindAll(
        TreeScope.Subtree, conditionNotButtons);
    Console.WriteLine("Elements other than buttons:");
    foreach (AutomationElement autoElement in elementCollectionNotButtons)
    {
        Console.WriteLine(autoElement.Current.Name);
    }
}
