TabControl Style in WPF

一般 我们在使用TabControl时，需要添加多个tab页，然后把不需要的tab页通过鼠标右键点击ContextMenu菜单的形式进行关闭，下面的代码是直接在tab页上面添加按钮事件，直接点击关闭按钮，就可以关闭tab页。

 

public class CloseableTabItem : TabItem
    {
        static CloseableTabItem()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(CloseableTabItem), new FrameworkPropertyMetadata(typeof(CloseableTabItem)));
        }

        public static readonly RoutedEvent CloseTabEvent =
            EventManager.RegisterRoutedEvent("CloseTab", RoutingStrategy.Bubble,
                typeof(RoutedEventHandler), typeof(CloseableTabItem));

        public event RoutedEventHandler CloseTab
        {
            add { AddHandler(CloseTabEvent, value); }
            remove { RemoveHandler(CloseTabEvent, value); }
        }

        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            Button closeButton = base.GetTemplateChild("PART_Close") as Button;
            if (closeButton != null)
                closeButton.Click += new System.Windows.RoutedEventHandler(closeButton_Click);
        }

        void closeButton_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            this.RaiseEvent(new RoutedEventArgs(CloseTabEvent, this));
        }
    }
