title: How to make ProgressBar undragable back?
body: <p>I Have a ProgressBar which is being used to select a value from 0 to max, Now everything is working good, However sometimes i would like to limit the ProgressBar to not be able to scroll back.
  The Bar is being used to select max players, later on the players are being chosen, and i want to block the abillity to set max players to lower then chosen players.</p>
  
  <p>Meaning that if the bar is set to 6, at some condition i want to make it unscrollable back, but only forward.</p>
  
  <p><strong>I Don't want to change the minimum</strong>, cause that will change the bar.</p>
  
  <p>How can i achive this?</p>
