WPF怎么调用按钮触发事件的方法

可以的，只是没什么意义

this.txtDelay_KeyDown(txtDelay, new KeyEventArgs(

    System.Windows.Input.Keyboard.PrimaryDevice,

    PresentationSource.CurrentSources.OfType<PresentationSource>().First(),

    Environment.TickCount,

    Key.A))

  // 定义事件属性

  public static readonly RoutedEvent ClickRoutedEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(ClickEventHandler), typeof(ControlName))

  

  [Description("点击时发生")]

        public event ClickEventHandler Click

        {

            add { AddHandler(ClickRoutedEvent, value) }

            remove { RemoveHandler(ClickRoutedEvent, value) }

        }

//触发点击事件，这里注册你控件上的那个点击按钮事件

void button_Click(object sender, RoutedEventArgs e)

{

    

            e.RoutedEvent = ScrollChangedRoutedEvent

            e.Source = this

            this.RaiseEvent(e)

}

原因是你在IsPressed时候设置的是Button的Background，这个值是用来确定Button正常显示时的背景的。因此没有反映。你可以通过重新定义Button的Template来解决该问题。给你个例子。你看看。

保存成文件后直接在浏览器中就能看到效果。IE、FF都可以
