how to Invisible one of the item in TRadioGroup?

Question

Any idea to make one of the options in TRadioGroup component invisible? (Delphi 7)

Answer 1

I think it would be more semantic to use Buttons[] property instead, so

RadioGroup.Buttons[Index].Visible := False

and usability-wise, to disable (Enabled := False) rather than to hide

Answer 2

RadioGroup1.Controls[...].Visible := False;
