Taken from the Avalon Controls Library (MS-PL) GitHub fork, RangeSlider lets you select a range of values with a slider, rather than a single value.

This control was updated to have more features


More events was added: DragStared/DragDelta/DragCompleted for Lower/Central/Upper thumbs Events for lower/upper value changed OldValues parameters in event args for rangeChanged event


Now range slider support vertical orientation


IsMoveToPointEnabled feature work like in Slider


when IsMoveToPointEnabled = False thumbs will move on the value you set in Small/LargeChange


This property will set interval between changing values when using Small/Larnge change.


If set to true, thumbs will snap to ticks like in standard Slider.

TickBars and Tickplacement

Range Slider receive support for displaying/hiding ticks and change its ticks width according to minimum and maximum values changed


If it set ExtendedMode = False you cannot do any manipulations inside range except moving thumbs closer/farther to each other with mouse, but if it enabled you can use MoveToPoint or Small/Large change inside range by clicking Left mouse button + left or right control button to move left thumb and Right mouse button + left or right control button to move right thumb inside range. If Extended mode = true you also can without problems move whole range by clicking leftmouse button


This property will let you move whole range when using MoveToPoint or Small/Large change (working also inside range)


Sets minimum width of central Thumb. It can be in range from 0 to range_slider_width/2.

AutoToolTipPlacement and AutotoolTipPrecision

AutoToolTipPlacement will display tooltip, which will move with Thumb and display current value. Implemented for left/central/right thumbs.

AutotoolTipPrecision set the number of digits, which will be shown after dot in autotooltip.
