or use void clear()
The example requires that you have created a Panel, a Button, and at least one other control on a Form. The other controls are added to the Panel control, and the Panel added to the Form. When the button is clicked, all the controls contained in the panel are removed from the Control.ControlCollection.
// Clear all the controls in the Panel.
private void clearButton_Click(object sender, System.EventArgs e)
{
panel1.Controls.Clear();
}
Remove all event handlers

if you want to undo a draw you've already done, you'd have to do something like reversible paint does, or you'll have to redraw the original image when you want to undo your draw.
