You can display week numbers using ShowWeekNumbers property.

Activating the week numbers:

  • ShowWeekNumbers="true"

There are two methods for calculating the week number:

  • ISO 8601 (Monday is the first day of week; the week that includes the first Thursday of January is the first week of year)
  • US (Sunday is the first day of week; the week that includes the January 1 is the first day of year) 

You can choose the algorithm by setting the WeekNumberAlgorithm:

  • WeekNumberAlgorithm.US - uses the US method
  • WeekNumberAlgorithm.ISO8601 - uses the ISO method
  • WeekNumberAlgorithm.Auto - decides upon the WeekStarts value (it uses ISO8601 if the first day of week is Monday, otherwise it uses US)
