how to create node on the panel?

[EDN Admin]

hey guys how can I change this code and make the Nodes to create on the panel instead of form???

<pre class="prettyprint using System;


namespace WindowsFormsApplication6
{
public partial class Form12 : Form
{
public List<MyNode> _Node = new List<MyNode>();
Random _rnd = new Random();
private MyPanel panel1 = new MyPanel();

public Form12()
{
InitializeComponent();

panel1.Location = new Point(269, 46);
panel1.Size = new Size(this.ClientSize.Width - 285, this.ClientSize.Height - 85);
this.Controls.Add(panel1);



this.Paint += new PaintEventHandler(Form1_Paint);
this.MouseDown += new MouseEventHandler(Form1_MouseDown);

}
