Drawing to the screen

Question

Hello,

 

I Want to draw a geometric object to the screen and then fill it. I can draw it, but don't come any further.

 

I have a button1_Click-Event:

private void button1_Click(object sender, EventArgs e)
{
      this.pictureBox1.Paint += new System.Windows.Forms.PaintEventHandler(this.FillEllipseRectangle);
}

 And then the FillEllipseRectangle-Event:

private void FillEllipseRectangle(object sender, PaintEventArgs e)
{
         MessageBox.Show("well done");
         ...
}

 I don't recieve the "well done"-message and nothing else in this method is being compiled.

 

I hope somebody can help me.
