Close window without code in WPF

Question

Is it possible to bind Buttonto closing Windowwithout adding events with code?

<Button Content="OK" Command="{Binding CloseWithSomeKindOfTrick}" />

Instead of the following XAML:

<Button Content="OK" Margin="0,8,0,0" Click="Button_Click">

With code:

private void Button_Click(object sender, RoutedEventArgs e)
{
    Close();
}

Thank!

If you want to close the dialog box Window, you can add the Button property IsCancel:

<Button Name="CloseButton"
        IsCancel="True" ... />

This means the following MSDN:

When you set the IsCancelbutton property to true, you create the button registered with AccessKeyManager. Then the button is activated when the user presses the ESC key.

MainWindow, Click, . , MVVM, :

public static class ButtonBehavior
{

    private static Window MainWindow = Application.Current.MainWindow;

    #endregion

    #region IsCloseProperty

    public static readonly DependencyProperty IsCloseProperty;

    public static void SetIsClose(DependencyObject DepObject, bool value)
    {
        DepObject.SetValue(IsCloseProperty, value);
    }

    public static bool GetIsClose(DependencyObject DepObject)
    {
        return (bool)DepObject.GetValue(IsCloseProperty);
    }

    static ButtonBehavior()
    {
        IsCloseProperty = DependencyProperty.RegisterAttached("IsClose",
                                                              typeof(bool),
                                                              typeof(ButtonBehavior),

                MainWindow.PreviewKeyDown += new KeyEventHandler(MainWindow_PreviewKeyDown);

            if (button != null)
                button.Click += new RoutedEventHandler(button_Click);
