The RangeSlider control was taken from the Avalon Controls Library (MS-PL) GitHub fork. It lets you select a range of values with a slider and 2 range bars, rather than a single value.

Properties

• Orientation: RangeSlider support vertical orientation
• IsMoveToPointEnabled feature work like for Slider
• SmallChange / LargeChange: when IsMoveToPointEnabled = False thumbs will move on the value you set in Small / LargeChange
• Interval: This property will set interval between changing values when using Small / Larnge change.
• IsSnapToTickEnabled: If set to true, thumbs will snap to ticks like in standard Slider.
• TickBars and Tickplacement: RangeSlider receive support for displaying / hiding ticks and change its ticks width according to minimum and maximum values changed
• ExtendedMode: 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
• MoveWholeRange: This property will let you move whole range when using MoveToPoint or Small/Large change (working also inside range)
• MinRangeWidth: Sets minimum width of central Thumb. It can be in range from 0 to range_slider_width/2.
• 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.
