Remarks

PreviousActivity property returns the previous activity that occurs before the earliest date in the ActivityQuery.DateRanges of the associated ActivityQuery object. It returns null if no such activity exists or that the information is not available, which could be because ActivityQuery's ActivityQuery.RequestedInformation flags didn't contain the ActivityQueryRequestedDataFlags.PreviousActivity flag, or the underlying data connector doesn't support being able to query for this information. You can check to see if the HasPreviousActivity property returns false to ascertain that such an activity doesn't exist.

This information is used by schedule controls to provide navigation user interface for navigating to the previous activity that occurs before the currently displayed activities.
