I am trying to change the value of a horizontal scrollbar from -1 to -2.
I am able to get access to it.. but next i have to change its value.. 

`AutomationElement _sideBar = _ClickButtonElement.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ClassNameProperty, "WindowsForms10.SCROLLBAR.app.0.378734a"));`

\_clickButtonElement is the AutomationElement of the parent window of the scrollbar.
