>I thought I would be able to set up in designer what text should be in the check box when it is checked and a different text when it is unchecked. But I can't find these properties. Do they exist?

But Dmitry, why would you want to change the text? Users understand what a checkmark in a CheckBox means and changing the text when its state changes can only result in confusion. Example: say your CheckBox text says "Subscribe To Newsletter". By checking the CheckBox, the user has opted to subscribe to a newsletter. After they've checked it, what would you change the text to? It wouldn't change to "Unsubscribe", because then it would appear that they've marked a CheckBox that says "Unsubscribe", but they wanted to Subscribe, not Un.

Maybe I'm missing an obvious use case for this, so could you enlighten me?
