You should do your graphics drawing in the forms Paint Event, otherwise as soon as the screen updates you will loose your drawing. This is a quick and dirty example on how to do so.

public Form1()
{
    InitializeComponent();
    this.Paint += new PaintEventHandler(Form1_Paint);
}

void Form1_Paint(object sender, PaintEventArgs e)
{
    Pen pen = new Pen(Color.Aquamarine,2);
    SolidBrush brush = new SolidBrush(Color.Aquamarine);

    e.Graphics.DrawEllipse(pen, 10, 10, 100, 20);
    e.Graphics.FillEllipse(brush, 10, 50, 100, 20);
}
