My DateTimePicker is bound to property:
picker.DataBindings.Add(\"Value\", this, \"EventDate\"); ... private DateTime eventDate; public DateT
I use this.
It works very well.
JsonConvert.SerializeObject(object, new JsonSerializerSettings() { DateFormatHandling = DateFormatHandling.IsoDateFormat, DateTimeZoneHandling = DateTimeZoneHandling.Local });
