前段时间，写了一个简单的鼠标拖动按钮控件的实现方式：

　　private void button1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { var element = sender as FrameworkElement; mousePosition = e.GetPosition(null); trackingMouseMove = true; if (null != element) { element.CaptureMouse(); element.Cursor = Cursors.Hand; } } private void button1_MouseMove(object sender, MouseEventArgs e) { var element = sender as FrameworkElement; if (trackingMouseMove) { double deltav = e.GetPosition(null).Y - mousePosition.Y; double deltaH = e.GetPosition(null).X - mousePosition.X; double newTop = deltav + (double)element.GetValue(Canvas.TopProperty); double newLeft = deltaH + (double)element.GetValue(Canvas.LeftProperty); element.SetValue(Canvas.TopProperty, newTop); element.SetValue(Canvas.LeftProperty, newLeft); mousePosition = e.GetPosition(null); } } private void button1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { FrameworkElement element = sender as FrameworkElement; trackingMouseMove = false; element.ReleaseMouseCapture(); mousePosition.X = mousePosition.Y = 0; element.Cursor = null;

　　该方法不能实现鼠标拖动功能，只因没有设置按钮的属性   ClickMode="Hover"，这样就可以实现了，看来一个按钮的属性也是相当重要啊大家写程序的时候不要小看他啊
