Scroll events in c#?

Question

C++ / C#

Is it possible to catch the scroll event on the form element and insert the value into the label?
I'm trying to do it but nothing happens... What am I doing wrong?

private void Form1_Scroll(object sender, ScrollEventArgs e)
        {
            Graphics g = pictureBox1.CreateGraphics();

            int xWidth = pictureBox1.Width;
            int yHeight = pictureBox1.Height;

            int x;
            int y;

            if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
            {
                x = e.NewValue;
                y = vScrollBar1.Value;
            }
            else //e.ScrollOrientation == ScrollOrientation.VerticalScroll
            {
                y = e.NewValue;
                x = hScrollBar1.Value;
            }

            g.DrawImage(pictureBox1.Image,
              new Rectangle(0, 0, xWidth, yHeight),  //where to draw the image
              new Rectangle(x, y, xWidth, yHeight),  //the portion of the image to draw
              GraphicsUnit.Pixel);

            pictureBox1.Update();

            label1.Text = x.ToString();
        }

1 - the contents of containers and not forms are usually copied. make sure you actually hang the handler on the container you're scrolling in
2 - use breakpoints to make sure you hit that handler at all
3 - once upon a time, I would probably start by putting a line like label1.Text = "bingo!";the very first one in the handler, and only then would complicate the logic
