title: How do i assign a RadioButton to a RadioGroup in XE2?
body: <p>Don't hate (or devote) me on this silly question, but i noticed on XE2 it has changed, i try to drop a new RadioButton to a RadioGroup and i notice it is actually NOT a part of that group, why ?</p>
  
  <p>and what is this TStrings i need to write ? it's kind of hard for me to control it like that.</p>
