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

1. 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->CancelButton = myCancelBtn;  
      }
