title: How can I draw over a panel in C#?
body: <p>Hey, I need to do my drawing over a panel in C# but without placing my drawing code inside "panel1_Paint", how can I do that ??
  BTW, I'm using WinForms.</p>
  
  <p><strong>Update</strong> : I forgot to make something clear, I need not to place my drawing code inside paint handler, because I need to start drawing depending on buttons' events.</p>
