c# – 使用XtraScheduler按特定自定义字段值获取约会

private DevExpress.XtraScheduler.SchedulerControl _SchedulerControl;
private DevExpress.XtraScheduler.SchedulerControl StandingSchedulerControl
{
    get
    {
        if (_SchedulerControl == null)
        {
            _SchedulerControl = new DevExpress.XtraScheduler.SchedulerControl();

            BindingSource bs = new BindingSource();
            bs.DataSource = StandingOrderList;

            _SchedulerControl.Storage = new SchedulerStorage(this.components);
            _SchedulerControl.Storage.Appointments.AutoReload = true;
            _SchedulerControl.Storage.Appointments.Mappings.Subject = "Description";
            _SchedulerControl.Storage.Appointments.Mappings.RecurrenceInfo = "RecurrenceInfo";
            _SchedulerControl.Storage.Appointments.Mappings.Type = "Type";

            _SchedulerControl.Storage.Appointments.CustomFieldMappings.Add(new DevExpress.XtraScheduler.AppointmentCustomFieldMapping("Inactive","Inactive"));
            _SchedulerControl.Storage.Appointments.CustomFieldMappings.Add(new DevExpress.XtraScheduler.AppointmentCustomFieldMapping("StandingOrderKEY","StandingOrderKEY"));
            _SchedulerControl.Storage.Appointments.DataSource = bs;
            _SchedulerControl.EditRecurrentAppointmentFormShowing += new EditRecurrentAppointmentFormEventHandler(_SchedulerControl_EditRecurrentAppointmentFormShowing);
        }
        return _SchedulerControl;
    }
}

其中“StandingOrderList”被定义为StandingOrder业务对象的列表.这可以正确地保存和恢复,但是在应用程序中可能只有一个值“StandingOrderKEY”,并且需要从该值获取存储中的Appointment对象.到现在为止,我的解决方案是：

private Appointment GetAppointmentByStandingOrderKEY(Guid standingOrderKEY)
{
    Appointment findAppointment = StandingSchedulerControl.Storage.Appointments.Items.Find(appointment => (Guid)appointment.CustomFields["StandingOrderKEY"] == standingOrderKEY);
    return findAppointment;
}

但是,StandSchedulerControl.Storage.Appointments.Items似乎只包含具有Normal或Pattern类型的约会,这意味着如果StandingOrderKEY与已保存的ChangedOccurrence或DeletedOccurrence相关联,则将找不到相关的约会.

我已经验证从列表创建的BindingSource实际上包含所有约会的例外.似乎当它被设置为AppointmentStorage的DataSource时,异常被置于其模式约会的“内部”,并且只能通过首先获得对父约会的引用然后在该约会上调用GetExceptions()并搜索最终收集了StandingOrderKEY.然而,这是一个问题,因为目前我们没有“父”约会的识别信息,只有例外的信息.

所以,我的问题如下(大致按照优先顺序排列)：

>有没有办法通过自定义字段值从约会存储中获取约会对象,忽略约会的类型？是否有包含例外和正常/模式约会的集合？
>我们知道约会预先成为例外,因为约会的类型已经存储.有没有办法搜索此特定自定义字段值的所有异常？
>有没有办法通过数据源引用从约会存储中获取约会对象？用作DataSource的BindingSource包含异常约会.有没有办法,给定BindingSource集合中的项目,将它与存储中的项目相关联？

欢迎任何其他建议.感谢您的关注！
