Scheduler - Recurrence Editor

Hi,

I can't find the RecurrenceEditor control in the WPF library.

There is one in the Blazor library which works perfectly, I need to create a custom appointment edit window with the recurrence editor on the form. What's the best way to do this using the WPF library? 

Thanks in advance, Lee.

Currently, we are checking the reported query from our end. we will update you on the further details on 16 March, 2022. We appreciate the patience until then.

Hi Lee, 
 
#Regarding Custom Recurrence Editor in WPF 
As per the implementation of SfScheduler, you can add the own custom appointment editor in the sfschedule with help of AppointmentEditoropening event. Please refer to the following KB documentation for your reference. 
 
 
We need more information of ‘What exactly you mention the RecurrenceEditor control library’. Could you please share the code snippet of blazor schedule or image of your requirement to achieve in WPF Scheduler which would help us to provide the better solution?

Hi SaiGanesh,

We just need a control to amend the recurrence rule. The built in appointment editor in the WPF library has the recurrence editor on it, is this not encapsulated within its own control?

On blazor, you simply do the following to display a recurrence editor:


 <SfRecurrenceEditor @bind-Value="@vm.Model.RecurrenceRule"

                                       StartDate="@vm.Model.DStart.DateTime" />


I cannot find the equivalent in the wpf library, however as mentioned above the functionality is obviously there as it is present on the default appointment edit form from your demo. (Screenshot attached)

Thanks, Lee.

Hi Lee, 
 
#Regarding RecurrenceEditor in custom Appointment Editor 
Your requirement can be achieved with the help of RecurrenceProperties in the SfScheduler. You can get the recurrence properties value of appointment with the help of RecurrenceHelper Class. With the help of RecurrenceHelper, you can get the recurrence properties of the appointment to display in the CustomAppointment Editor. Please refer to the following code snippet for your reference. We have created the demo sample of CustomAppointment editor with Daily Reccurence. 
 
Code snippet 
if (appointment.IsRecursive) 
    { 
        var id = appointment.Type == AppointmentType.ChangedOccurrence ? appointment.RecurrenceId : appointment.Id; 
        var parentAppointment = (ScheduleAppointment)this.GetParentAppointment(id); 
        this.appointment = parentAppointment; 
        SchedulerRecurrenceProperties = RecurrenceHelper.RRuleParser(appointment.RecurrenceRule, appointment.StartTime); 
        if (SchedulerRecurrenceProperties.RecurrenceType == RecurrenceType.Daily) 
        { 
            this.Repeat.Visibility = Visibility.Visible; 
            this.Repeat.Value = SchedulerRecurrenceProperties.Interval; 
            this.Recurrence.Text = "Daily"; 
 
            if (SchedulerRecurrenceProperties.RecurrenceRange == RecurrenceRange.NoEndDate) 
            { 
                this.DailyRecurrenceUntil.Visibility = Visibility.Collapsed; 
                this.DailyRecurrenceRepeat.Visibility = Visibility.Collapsed; 
                this.End.Text = "Never"; 
            } 
            else if (SchedulerRecurrenceProperties.RecurrenceRange == RecurrenceRange.EndDate) 
            { 
                this.DailyRecurrenceUntil.Visibility = Visibility.Visible; 
                this.DailyRecurrenceRepeat.Visibility = Visibility.Collapsed; 
                this.DailyRecurrenceUntil.Value = SchedulerRecurrenceProperties.EndDate; 
                this.End.Text = "UNTIL"; 
            } 
            else 
            { 
                this.DailyRecurrenceUntil.Visibility = Visibility.Collapsed; 
                this.DailyRecurrenceRepeat.Visibility = Visibility.Visible; 
                this.DailyRecurrenceRepeat.Value = SchedulerRecurrenceProperties.RecurrenceCount; 
                this.End.Text = "Count"; 
            } 
        } 
    } 
    else 
    { 
        this.Recurrence.Text = "Never"; 
        this.End.Text = "Never"; 
        this.Repeat.Visibility = Visibility.Collapsed; 
        this.End.Visibility = Visibility.Collapsed; 
        this.DailyRecurrenceUntil.Visibility = Visibility.Collapsed; 
        this.DailyRecurrenceRepeat.Visibility = Visibility.Collapsed;

Hi SaiGanesh,


I don't think you have understood my question as the above information isn't relevant.


On the default appointment form, as you have it in the demo you have sent, there is a control to select the recurrence type and then amend the options for that type; See my previous screenshot which highlighted the area on the form in red. 


Where is that control in the WPF Library? The blazor library has one, you are using the control (Or at least something to amend the recurrence of the events) on your default form so it must be there.

Lee.

Hi Lee, 
 
#Regarding Recurrence Editor Library 
As per the implementation of SfScheduler, we do not have a separate recurrence library. We are using the recurrence properties to create the respective recurrence UI and display it in the appointment editor. With the help of the RecurrenceHelper class, you can get the recurrence properties of the appointment.

Hi SaiGanesh,

This is dissapointing to hear. Not sure why the Blazor library has this control and the WPF library doesn't. 
It would surely be a case of encapsulating the recurrence section from the appointment editor? 


Otherwise users have to write their own control for what is a standard rule pattern.


Lee.

Hi Lee,


#Regarding Recurrence Editor Library

As we have mentioned in the previous update, we do not have a separate recurrence library as in the scenario of adding any customized editor for the recurrence editor. You can use the recurrence properties to bind the values in a custom control to the recurrence editor, just like the subject, start, and end time properties are bound to the custom editors.
