第一步 在自定义控件里加上声明
/// <summary> /// The click event /// </summary> public static readonly RoutedEvent userControlClickEvent = EventManager.RegisterRoutedEvent("UserControlClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(CommonButton)); /// <summary> /// 控件点击的操作. /// </summary> public event RoutedEventHandler UserControlClick { add { AddHandler(userControlClickEvent, value); } remove { RemoveHandler(userControlClickEvent, value); } }
第二步 给自定义控件的按钮的click里添加调用
public void btnClick(object sender, RoutedEventArgs e) { RoutedEventArgs args = new RoutedEventArgs(userControlClickEvent, this); RaiseEvent(args); }
第三步 外部调用该事件
CommonButton button = new CommonButton(); button.UserControlClick += Button_UserControlClick; button.Width = 200; button.Height = 200; button.ImagePathNormal = "/Images/LeftMenuButtons/left_menu_1_normal.png"; button.ImagePathPressed = "/Images/LeftMenuButtons/left_menu_1_selected.png"; button.SetValue(Canvas.ZIndexProperty, 999); button.SetValue(Canvas.LeftProperty, (double)0); button.SetValue(Canvas.TopProperty, (double)0); mainCanvas.Children.Add(button);
private void Button_UserControlClick(object sender, RoutedEventArgs e) { MessageBox.Show("已执行"); }
