AvalonDock-将菜单项绑定到可停靠内容的状态

一种可能的解决方案是使用附加属性。附加属性将调用必要的方法来更改状态。你就可以把它绑起来。

public static class ContentAttach
{
    public static readonly DependencyProperty StateProperty = DependencyProperty.RegisterAttached(
        "State", typeof(DockableContentState), typeof(ContentAttach), new PropertyMetadata(StateChanged));
    public static void SetState(DockableContent element, DockableContentState value)
    {
        element.SetValue(StateProperty, value);
    }
    public static DockableContentState GetState(DockableContent element)
    {
        return (DockableContentState)element.GetValue(StateProperty);
    }
    private static void StateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var element = (DockableContent)d;
        var state = (DockableContentState)e.NewValue;
        switch (state)
        {
            // Call methods in here to change State.
        }
    }
}
