body: <p>.Net: Why we can't access to some properties of a control programmatically in winforms? For example, "Locked" property of a groupbox is not accessible via code. So What Possibly can I do when I want to locked it programmatically ?  Using Enabled = False will greyed out all controls within it and this is not what I wanna to be.</p>
  
  <p>Any Suggestions ?</p>
