Remarks

The GetAppointmentsToInsert<T> method creates a fake Scheduler but does not apply all scheduler settings specified in the view, for better performance. Then, an appointment being inserted is retrieved from this Scheduler instance.

Utilizing the GetAppointmentsToInsert<T> method allows you to handle recurring appointments correctly. Now, when an end-user selects and moves multiple recurring appointments at the same time, the corresponding number of database records will be created. For example, if two recurring appointments are moved simultaneously, two records will appear in the database.

For an example of use, refer to the following code snippet.

View Example: Scheduler - How to implement the FetchAppointment event functionality

@Html.DevExpress().Scheduler(SchedulerSettingsHelper.CommonSchedulerSettings).Bind(Model.FetchAppointments, Model.Resources).GetHtml()
static void UpdateAppointment() {

    DBAppointment[] insertedAppt = SchedulerExtension.GetAppointmentsToInsert<DBAppointment>(SchedulerSettingsHelper.CommonSchedulerSettings,
        SchedulerDataHelper.FetchAppointmentsHelperMethod,
        SchedulerDataHelper.GetResources());
    foreach (var appt in insertedAppt) {
        SchedulerDataHelper.InsertAppointment(appt);
    }

    DBAppointment[] updatedAppt = SchedulerExtension.GetAppointmentsToUpdate<DBAppointment>(SchedulerSettingsHelper.CommonSchedulerSettings,
        SchedulerDataHelper.FetchAppointmentsHelperMethod,
        SchedulerDataHelper.GetResources());

    foreach (var appt in updatedAppt) {
        SchedulerDataHelper.UpdateAppointment(appt);
    }

    DBAppointment[] removedAppt = SchedulerExtension.GetAppointmentsToRemove<DBAppointment>(SchedulerSettingsHelper.CommonSchedulerSettings,
        SchedulerDataHelper.FetchAppointmentsHelperMethod, 
        SchedulerDataHelper.GetResources());
    foreach (var appt in removedAppt) {
        SchedulerDataHelper.RemoveAppointment(appt);
    }
