title: Toolstrip with check button group
body: <p>I'd like to have a toolstrip with some buttons on it (WinFroms/c#/.net4). I'd like to have the clicked button be checked and all others unchecked, so I want to have only the clicked button checked, all the others unchecked. </p>
  
  <p>I know toolstrip button has checkedonlclick property, but when I click one button, others may be also checked. In good old VB6 there was an automatic solution for this problem: buttongroup on toolbar. Is there any similar in Winfoms?</p>
  
  <p>Or should I handle it from code?! Switch all other buttons to unchecked state when one button is checked? If so, then it would not be my favourite solution...</p>
