    /// <example>
    /// This example demonstrates how to create a Button, hook it up to a Command with a minimum of code and let the power of data binding deal with turning the command on and off:
    /// <code>
    /// Button button = new Button();
    /// Command command = new ArbitraryCommand("My Data");
    /// button.DataBindings.Add("Text", command, "DisplayName");
    /// button.DataBindings.Add("Enabled", command, "Enabled");
    /// button.Click += delegate { command.Execute();  };
    /// </code>
    /// </example>
