Hi i have tried to use your calendarinfo and ultratimelineview and when i use the designer ... he always throw me this exception "In current data source there is no column named: Id"

I have a Id in my databinding class

public class Person
    {
      public string Name { get; set; }
      public int Id { get; set; }
    }

this.ultraCalendarInfo1.DataBindingsForAppointments.BindingContextControl = this;
      this.ultraCalendarInfo1.DataBindingsForOwners.BindingContextControl = this;
     this.ultraCalendarInfo1.DataBindingsForOwners.DataSource = this.personBindingSource;
      this.ultraCalendarInfo1.DataBindingsForOwners.KeyMember = "Id";
      this.ultraCalendarInfo1.DataBindingsForOwners.NameMember = "Name";
