2、后端代码实现
1 private void Grid_MouseDown(object sender, MouseButtonEventArgs e)
2 {
3 DoubleAnimation da = new DoubleAnimation();
4 da.Duration = new Duration(TimeSpan.FromSeconds(1));
5 if (e.ClickCount == 2)
6 da.To = 0d;
7 else
8 da.To = 180d;
9 AxisAngleRotation3D aar = Application.Current.MainWindow.FindName("aar") as AxisAngleRotation3D;
10 aar.BeginAnimation(AxisAngleRotation3D.AngleProperty, da);
11 }
