Label placement
The LabelsPlacement property is used to place the labels either between the major ticks or on the major ticks. The default value of the LabelsPlacement property is SliderLabelsPlacement.OnTicks.

NOTE
Refer here to customize label text format through range slider events.
Edge labels placement
The EdgeLabelsPlacement property is used to move the first and the last label either inside the track bounds or based on the intervals. The default value of the EdgeLabelsPlacement property is SliderEdgeLabelPlacement.Default.
If the TrackExtent > 0 and the EdgeLabelsPlacement is SliderEdgeLabelsPlacement.Inside, the labels get placed inside the extended track edges.

Label style
Change the active and inactive label appearance of the Range Selector using the ActiveTextColor, ActiveFontSize, ActiveFontFamily, ActiveFontAttributes, InactiveTextColor, InactiveFontSize, InactiveFontFamily, InactiveFontAttributes and Offset properties of the LabelStyle class.
The active side of the Range Selector is between the start and end thumbs.
The inactive side of the Range Selector is between the Minimum value and the left thumb, and the right thumb and the Maximum value.

Label offset
Adjust the space between ticks and labels of the Range Selector using the Offset property. The default value of the Offset property is 5.0 when ShowTicks enabled, otherwise it is 15.0 by default.
