Solution 1

Can pass Graphics instance or that Control instance as parameter to the function:

C#

private void DrawFunction(Control control)
{
   // Create a Graphics object for the Control.
   Graphics g = control.CreateGraphics();
   // Draw shapes etc...
}

private void DrawFunction(Graphics graphics)
{
   //Draw shapes etc...
}

Thank you, it is great code. I have found out another solution:

private void DrawFunction(System.Drawing.Printing.PrintPageEventArgs e)
{
// Draw shapes etc...
}

"e" parameter is got from Paint event of the control. Thank you very much.
