Nadya,
You set the opg.Value to 1 if you want the button with te value of 1 selected.
>I set ButtonCount to 0 in my class, but it didn't solve the problem :( In my code I set first option to 1 programmatically, then another option to 1 programmatically. As a result I see two options selected. But I need only the last option, which I set, to be selected. How can I solve the problem in easy way?

UPDATE. I've just created a test form with option group with 3 option buttons. I programmatically set button's values to 1 (2nd and 3rd) and as a result all 3 options were selected. I'm wondering, what is the behavior in VFP7/8 and is this considered a bug or not?
