Major and Minor Scales in Xamarin.Android RangeNavigator

30 Nov 20224 minutes to read

SfDateTimeRangeNavigator displays major and minor scales at the top and bottom position of the control. You can also control its visibility using MajorScaleStyle.Visible and MinorScaleStyle.Visible properties.

Intervals

By default, best possible interval component will be chosen for both major and minor scales based on the available size of the view. For example, if the available space is sufficient to show only year labels without overlapping, interval will be displayed in years. However, you can also set specific DateTimeIntervalType components using Intervals property as demonstrated in the below code snippet.

C#

[C#]
SfDateTimeRangeNavigator dateTime = new SfDateTimeRangeNavigator(this);
dateTime.Intervals = EnumSet.Of(DateTimeIntervalType.Year, DateTimeIntervalType.Month);
