Refresh RadCalendar

[Ian]

I have a subclass of RadCalender which has an additional collection of items, which I'm binding to the calendar using a custom cell.

So, I have two issues...

1. How do I asynchronously bind this additional collection to the calendar? (The data comes from a web service.)

2. How do I reload the data when it's changed?

Hi Ian,

You can find the task of asynchronous loading of items collections discussed in various threads out in the internet, e.g. this Stack Overflow thread. Onto the second question -- RadCalendar does not expose a method for full reload as it handles updates internally. In order to act on changes in your collection, you may consider using custom renderers, inheriting from the existing CalendarRenderer classes. You can then send messages to these renderers from your Xamarin Forms control using the Xamarin Forms MessagingCenter. Then, upon receiving these, you can invoke the corresponding native control's method: InvalidateUI on Windows, RebuildCalendar on Android and ReloadData on iOS.

Best regards,

Reassigning the AppointmentsSource triggers a rebind.
