Bret,
I have bound an optiongroup to a M/F gender field, but wanted the full text M/F to display. I set the captions to M and F and dropped labels of Male/Female right behind the M/F. All I had to do was link the click event of the label to the correct button. Only the letters M and F highlight but that was acceptable.
>I have a group of option groups used to select from multiple related reports and send them to preview, print, etc. They are arranged like rows and columns. I use labels above the columns and to the left of the rows. Labels can also be handy if they make formatting easier. I use some long labels next to some check boxes because check box captions don't word wrap. I could probably have inserted a carriage return in the caption, but a label seemed easier. There may be any number of cases where a caption COULD be used, but I wanted, in principle, to ensure that all my option buttons and check boxes could be seen to get focus whether I deliberately included a caption in each instance or not.
