Draw graphics outside client-area?

[d98tp]

Hi

I have a panel (with auto-scroll = true) that I make dynamic drawings in. When I draw something inside the size of the panel everything is fine. But if something is drawn outside of the panel-size the scrolling doesn´t show. The scroll only shows if I draw (e.g. make visible and set a location) some windows-form-control (e.g. LinkedLabel) outside the area. But then the drawn image that should be outside the area isn´t there when I scroll. And when I scroll back the image that was there before now is gone...

I understand that it has to be some problem about how I update the image but I haven´t been able to fix it. I want to "draw" a big drawing and then be able to scroll around to see the whole picture.

I make all my drawings in Paint-events, is this wrong? It´s a regular windows application. How should I solve this problem?

Thanks in advance.

Example on my problem (only importent code):

public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Panel panel1;
private System.Windows.Forms.LinkLabel linkLabel1;
public Form1()
{
InitializeComponent();
this.linkLabel1.Location = new System.Drawing.Point(1500, 150);
}
static void Main()
{
Application.Run(new Form1());
}

private void panel1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
e.Graphics.DrawLine(new Pen(Brushes.Black, 2.0f),20,20,1500,250);
}
