When using GetRecurrenceDateTimeCollection if the RRule passed in does not contain a "COUNT=x" then the recurrence will not return anything

I noticed that when using this method the RRule for an indefinite recurrence, never returns any appointments, in v17.1.0.40.

For example an RRule of: FREQ=WEEKLY;BYDAY=TU;INTERVAL=2 will not return any values

whereas an RRule of: FREQ=WEEKLY;BYDAY=TU;INTERVAL=2;COUNT=5 will return values.

I noticed in v17.1.0.32 there was apparently a fix for this using NoEndDate, is this a value I need to pass in or something?

Hi Akin, 

 

Thank you for contacting Syncfusion support. 

 

We have analyzed the reported behavior “GetRecurrenceDateTimeCollection method doesn’t return any data when the NoEndDate recurrence set” and it works fine as expected from our end, we have prepared a simple and added an recurrence appointment by using the rule you have mentioned and it works fine as expected in all the applicable view. 

 

To get the data for the required range you need to pass the range start date and range end date to the GetRecurrenceDateTimeCollectionMethod. 

 

In our sample we have get the recurrence date time collection for the visible date ranges by using the VisibleDatesChangedEvent, and in this event we have pass the visibledate range from the VisibleDatesChangedEventArgument, and we have pass the start range by modifying the time to start of the day as it returns the current time as the value and the appointment start time may fall before the time. 

 

Code snippet: 

C# 

 

 

Sample: Schedule 

 

Note: As you mentioned we have included this fix in our Volume 1 Beta release version 17.1.0.32, hence kindly update to our latest version to resolve the issue. 

 

If the sample doesn’t meet your requirement, kindly revert us by modifying the sample and share more details and replication procedure which help us to analyze and resolve the reported issue.

I've used your sample and narrowed down the problem.

I've been following the instructions in the following link: https://help.syncfusion.com/xamarin/sfschedule/recurrence

Our implementation looks something like follows:

where the rangeStartDate is the first day of the current month, and the rangeEndDate is the last day of the current month.

Even when using the following 

I still get no values, unless I have a "COUNT=x" as part of the RRule being passed in (appointment.RecurrenceRule)

Thanks, Akin
