WPF UserControl里可供绑定的属性

/// 
        /// 重写基类 Margin        /// 
        public new Thickness Margin        {            get { return (Thickness)GetValue(MarginProperty); }            set { SetValue(MarginProperty, value); }        }        public new static readonly DependencyProperty MarginProperty = DependencyProperty.Register("Margin", typeof(Thickness), typeof(MirrorGrid), new FrameworkPropertyMetadata(new Thickness(0), new PropertyChangedCallback(OnMarginChanged)));        private static void OnMarginChanged(DependencyObject target, DependencyPropertyChangedEventArgs e)        {            ((FrameworkElement)target).Margin = (Thickness)e.NewValue;        }

UserControl 里的事件路由

/// 
        /// 声明路由事件        /// 参数:要注册的路由事件名称，路由事件的路由策略，事件处理程序的委托类型(可自定义)，路由事件的所有者类类型        /// 
        public static readonly RoutedEvent OnToolTipShowEvent = EventManager.RegisterRoutedEvent("OnToolTipShow", RoutingStrategy.Bubble, typeof(RoutedEventArgs), typeof(UserControl));        /// 
        /// 处理各种路由事件的方法         /// 
        public event RoutedEventHandler OnToolTipShow        {            //将路由事件添加路由事件处理程序            add { AddHandler(OnToolTipShowEvent, value,false); }            //从路由事件处理程序中移除路由事件            remove { RemoveHandler(OnToolTipShowEvent, value); }        }

路由事件

private void RoutedToolTipShow(RoutedEventArgs param)        {            param.RoutedEvent = OnToolTipShowEvent;            param.Source = this;            this.RaiseEvent(param);        }

控件附加属性

public abstract class AquariumServices : DependencyObject    {        public enum Bouyancy {Floats,Sinks,Drifts}        public static readonly DependencyProperty BouyancyProperty = DependencyProperty.RegisterAttached(          "Bouyancy",          typeof(Bouyancy),          typeof(AquariumServices),          new PropertyMetadata(Bouyancy.Floats)        );        public static void SetBouyancy(DependencyObject element, Bouyancy value)        {            element.SetValue(BouyancyProperty, value);        }        public static Bouyancy GetBouyancy(DependencyObject element)        {            return (Bouyancy)element.GetValue(BouyancyProperty);        }    }
