title: How to group Groups of radio buttons in Windows forms
body: <p>I have a form with a number of radiobuttons where only one should be selected at a time. </p>
  
  <p>Some of the radiobuttons are connected and need to bee explained by a header. For this i put them in a Groupbox. But then is the radiobuttons inside the groupbox no longer connected to the ones outside and its possible to select two off them.</p>
  
  <p>Is there a way to connect the radiobuttons so they all react on eachother? Or is there a better way to group and explain the radiobuttons then using a groupbox?</p>
