  • Range slider - The RadSlider can display one or two dragHandles thus providing you with the ability to select a single value or a range of values from a defined range
  • Decrease/Increase/Drag Handles - The slider layout can be customized using one of the handle properties that control which slider handles will be displayed - Increase Handle, Decrease Handle or Drag Handle
