RangeStart="2012-01-01"
RangeEnd="2016-01-01"
Interval="2"
ShowLabels="True"
ShowTicks="True">
</sliders:SfDateTimeRangeSlider>SfDateTimeRangeSlider rangeSlider = new SfDateTimeRangeSlider();
rangeSlider.Minimum = new DateTime(2010, 01, 01);
rangeSlider.Maximum = new DateTime(2018, 01, 01);
rangeSlider.RangeStart = new DateTime(2012, 01, 01);
rangeSlider.RangeEnd = new DateTime(2016, 01, 01);
rangeSlider.Interval = 2;
rangeSlider.ShowLabels = true;
rangeSlider.ShowTicks = true;
Date format
The DateFormat property is used to format the date labels. The default value of the DateFormat property is string.Empty.
<sliders:SfDateTimeRangeSlider Minimum="2000-01-01T09:00:00"
Maximum="2000-01-01T17:00:00"

RangeEnd="2000-01-01T15:00:00"
Interval="2"
IntervalType="Hours"
ShowLabels="True"
DateFormat="h tt"
ShowTicks="True">
</sliders:SfDateTimeRangeSlider>SfDateTimeRangeSlider rangeSlider = new SfDateTimeRangeSlider();
rangeSlider.Minimum = new DateTime(2000, 01, 01, 09, 00, 00);
rangeSlider.Maximum = new DateTime(2000, 01, 01, 17, 00, 00);
rangeSlider.RangeStart = new DateTime(2000, 01, 01, 11, 00, 00);
rangeSlider.RangeEnd = new DateTime(2000, 01, 01, 15, 00, 00);
rangeSlider.Interval = 2;
rangeSlider.DateIntervalType = SliderDateIntervalType.Hours;
rangeSlider.DateFormat = "h tt";
rangeSlider.ShowLabels = true;
rangeSlider.ShowTicks = true;
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.
<sliders:SfDateTimeRangeSlider Minimum="2011-01-01"
Maximum="2016-01-01"
RangeStart="2012-01-01"
RangeEnd="2015-01-01"
Interval="1"
LabelsPlacement="BetweenTicks"
ShowLabels="True"
ShowTicks="True">
</sliders:SfDateTimeRangeSlider>SfDateTimeRangeSlider rangeSlider = new SfDateTimeRangeSlider();
rangeSlider.Minimum = new DateTime(2011, 01, 01);
rangeSlider.Maximum = new DateTime(2016, 01, 01);
rangeSlider.RangeStart = new DateTime(2012, 01, 01);
rangeSlider.RangeEnd = new DateTime(2015, 01, 01);
rangeSlider.Interval = 1;
rangeSlider.LabelsPlacement = SliderLabelsPlacement.BetweenTicks;
rangeSlider.ShowLabels = true;
rangeSlider.ShowTicks = true;

Edge labels placement
The EdgeLabelsPlacement property is used to move the first and 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 EdgeLabelsPlacement is SliderEdgeLabelsPlacement.Inside, the labels get placed inside the extended track edges.
<sliders:SfDateTimeRangeSlider Minimum="2010-01-01"
Maximum="2018-01-01"
RangeStart="2012-01-01"
RangeEnd="2016-01-01"
Interval="2"
ShowLabels="True"
ShowTicks="True"
EdgeLabelsPlacement="Inside" />SfDateTimeRangeSlider rangeSlider = new SfDateTimeRangeSlider();
rangeSlider.Minimum = new DateTime(2010, 01, 01);
rangeSlider.Maximum = new DateTime(2018, 01, 01);
rangeSlider.RangeStart = new DateTime(2012, 01, 01);
rangeSlider.RangeEnd = new DateTime(2016, 01, 01);
rangeSlider.Interval = 2;
rangeSlider.EdgeLabelsPlacement = SliderEdgeLabelsPlacement.Inside;
rangeSlider.ShowLabels = true;
rangeSlider.ShowTicks = true;
Label style
Change the active and inactive label appearance of the range slider using the ActiveTextColor, ActiveFontSize, ActiveFontFamily, ActiveFontAttributes, InactiveTextColor, InactiveFontSize, InactiveFontFamily, InactiveFontAttributes and Offset properties of the LabelStyle class.
The active side of the DateTime Range Slider is between the start and end thumbs.
The inactive side of the DateTime Range Slider is between the Minimum value and the left thumb, and the right thumb and the Maximum value.

rangeSlider.ShowTicks = true;
rangeSlider.LabelStyle.Offset = 10;
