How to: Designate a Windows Forms Button as the Cancel Button

On any Windows Form, you can designate a Button control to be the cancel button. A cancel button is clicked whenever the user presses the ESC key, regardless of which other control on the form has the focus. Such a button is usually programmed to enable the user to quickly exit an operation without committing to any action.

To designate the cancel button

• Set the form's CancelButton property to the appropriate Button control.

  Private Sub SetCancelButton(ByVal myCancelBtn As Button)
     Me.CancelButton = myCancelBtn
  End Sub
  

private void SetCancelButton(Button myCancelBtn)
{
   this.CancelButton = myCancelBtn;
}

private void SetCancelButton(Button myCancelBtn) 
{
   this.set_CancelButton(myCancelBtn);
}

private:
   void SetCancelButton(Button ^ myCancelBtn)
   {
      this->CancelButton = myCancelBtn;
   }
