Some additional information: If I drag and drop or expand (with the mouse) one item in the schedule, it updates the database and it works. If I click on the item and then click on Edit Appointment : after I select all my options and click save... I get the error:
in Batch([FromBody] EditParams param)
Because param is null. I am not sure what am I missing. Please advise.
Thanks
I solve part of the problem: the fields
public int AllDay { get; set; }
public int Recurrence { get; set; }
HAVE to be boolean. My mistake! After that the item in the calendar get updated even using the option of edit appointment, however: I have to refresh the page to see the changes. Still looking for a solution on that issue.
