Here is my UserControl

And i call the StoryBoard like that:

    private void MyTest_MouseDown(object sender, MouseButtonEventArgs e)
    {
        Storyboard sbdCardAnim = (Storyboard)MyTest.Grid.Resources["Path_Ani"];
        sbdCardAnim.Begin();
    }

And i get this error when i click:

    '[Unknown]' property does not point to a DependencyObject in path '(0).(1)[3].(2)'.
