A library or utility for expanding RFC 2445 recurring appointments

created 4 years ago

We are successfully using your RFC 2445 support for recurring appointments in dxscheduler:
https://js.devexpress.com/Documentation/Guide/Widgets/Scheduler/Appointments/Appointment_Types/#Recurring_Appointments

However, we also need expanded appointments in lists (e.g. the dxdatagrid, but also in the dxlist). Currently, we are using SQL CLRs to expand these but this is slow and hems us providing the application as a cloud-service. we are looking for a way to employ your RFC 2445 algorithm in more of your controls or even in non-devexpress-based components (e.g. a label that shows the next appointment, which also considers recurring appointments). is there any public api of yours that we can use? like "rfc2445Utils"? how can we achieve showing recurring appointments in a list-control / datagrid?

Regards

Hi Michael,

Consider the RRule library for this task. We use it in our internal code to create\manage recurrence rules. This library has the all method, which returns a list of dates. You can use this list to generate a plain list of appointments and display them in dxDataGrid\dxList.

Thanks,
Artem
