Windows Forms

class CustomButton : Button 
{
  Bitmap displayimage;
  bool down;
  public CustomButton()
  {
       MouseUp += OnMouseUp
       MouseDown += OnMouseDown  //etc.. for other mouse events
  }

  private void OnMouseDown(object sender, MouseEventArgs e)
  {
    down = true;
    displayimage = new Bitmap("pressedimage.png");
    Invalidate();
  }

  private void OnMouseUp(object sender, MouseEventArgs e)
  {
    down = false;
    displayimage = new Bitmap("inactiveimage.png");
    Invalidate();
  }

  protected override void OnPaint(PaintEventArgs e)
  {
           if (down)
            {
                Matrix matrix = new Matrix();
                matrix.Translate(1, 1, MatrixOrder.Prepend);
                e.Graphics.Transform = matrix;
            }
      e.Graphics.DrawImage(bitmapImage);
      e.Graphics.DrawString(displaystring);
         base.OnPaint(e);   
  }
}

The buttons are created in the main Form class and we also listen to MouseDown event here :

class WinForm1 : Form
{
  CustomImageButton button = new CustomImageButton ();
  
  public WinForm1
  {
    button.MouseDown += OnButtonMosueDown;
  }

  private void OnButtonMosueDown(object sender, MouseEventArgs e)
  {
     //take some action , log the user click action
  }
}
