You can destory the instance of the form and generate the new instance of the same form and then show this. 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 http://stackoverflow.com/questions/91778/how-to-remove-all-event-handlers-from-a-control 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.

If you have textbox that you want to clear then private void button5_Click(object sender EventArgs e) { RecursiveClearTextBoxes(this.Controls); } private void RecursiveClearTextBoxes(Control.ControlCollection cc) { foreach (Control ctrl in cc) { TextBox tb = ctrl as TextBox; if (tb != null) tb.Clear(); else RecursiveClearTextBoxes(ctrl.Controls); } }
