title: RadioGroup in c++ builder
body: <p>I have two forms in my project in c++ Builder 2010. I have created RadioGroup in the second and listed all my buttons there, but I have few problems:</p>
  
  <ol>
  <li><p>When I load my form and check some button, the earlier selection stays checked until I hover mouse over it.</p></li>
  <li><p>How to make the buttons from second form affect the first form?</p></li>
  <li><p>How to make certain TEdit box go grey and unselectable when checking certain radiobuttons?</p></li>
  </ol>
