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

On any Windows Form, you can designate a xref:System.Windows.Forms.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 xref:System.Windows.Forms.Form.CancelButton%2A property to the appropriate xref:System.Windows.Forms.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;  
      }
