title: Controling Tab page changes Winforms
body: <p>I am building a .Net 3.5 WinForms based questionnaire comprising 9 steps (each on a tab page using a TabControl control). I would like users to move to the next tab ONLY when they click a "Next Step" button I've provided and not jump to later steps by clicking on the tab buttons above. 
  Basically, I dont want them to see contents of later steps/tab pages without completing the current step/tab page they are on, and then clicking my "Next Step" button.
  Any ideas would be appreciated. Cheers.</p>
