Opacity property for button?

If you want to make the button invisible, why dont you set its Visible property to false? Also, I think if you change the opacity of the button to make it less visible, it will actual create a "hole" in the form and you will not only be seeing through the button, but seeing through the form as well.

You might try to create a new button class that inherits from Button, then youll be able to access all of its protected members which may help you out.
