Analog clock rotate transform

Question

I have problem with rotate transform in my analog clock.

for (int i = 0; i <= 12; i++)
{
    Ellipse teckaa = new Ellipse();
    teckaa.Height = 30;
    teckaa.Width = 30;
    teckaa.Stroke = Brushes.Black;
    teckaa.Fill = Brushes.Black;
    canvas.Children.Add(teckaa);
    Canvas.SetTop(teckaa, 25);
    Canvas.SetLeft(teckaa, 215);
    RotateTransform otoceni = new RotateTransform(i*30, 230, 230);
    canvas.RenderTransform = otoceni;
}

I have this code for hour points, but this is moving only with one point. Is there any way how to change name of the ellipse in cycle for()?

Answer 1

Apply the Transform to the individual hour markers and not the the entire Canvas:

for (int i = 0; i <= 12; i++)
{
    Ellipse teckaa = new Ellipse();
    teckaa.Height = 30;
    teckaa.Width = 30;
    teckaa.Stroke = Brushes.Black;
    teckaa.Fill = Brushes.Black;
    canvas.Children.Add(teckaa);
    Canvas.SetTop(teckaa, 25);
    Canvas.SetLeft(teckaa, 215);
    RotateTransform otoceni = new RotateTransform(i*30, 230, 230);

    //canvas.RenderTransform = otoceni;
    teckaa.RenderTransform = otoceni;     
}

And see Petzold for a really cool all XAML clock.
