title: c# RichTextBox - scrolling with hidden ScrollBar
body: <p>I have RichTextBox control with hidden both Scrollbars. When they are hidden I can't scroll text with mouse, I can only use PgUp and PgDown keys to move the text.</p>
  
  <p>But I want to scroll with mouse when ScrollBars are disabled, is there any way I can do this?</p>
