SelectionChanged starts calling twice when appointments collection is changed at runtime from within the event.

The problem occurs when I update the Events property on either of the events DisplayDateChanged or SelectionChanged. It seems these events are triggered another time, sometimes, when the AppointmentSource gets refreshed. I say sometimes because you can navigate through the weeks as normal, but as some points you notice something went wrong. Here’s a list of what I have encountered so far :
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. Then a random week would have an other selected day (Friday). It would happen randomly until some weeks get skipped completely.
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. If I touch the Friday box,  the selected date gets initially updated  to Friday and then a random day between Monday and Friday gets selected.
When sliding through the weeks from the days header, the calendar gets stucked on a random week, and sliding forward or backward through the days header just put you back to the same week. In this case the only way to move to the next/previous week is to slide through the time slot.

Provide methods to serialize/deserialize recurrence patterns

When we have overlapping appointments in DayView with different Start and End times, TimeSlotTapped is not triggered for empty slots in between appointments.

When DayStartTime property is set and the user taps on the first timeslot, the start time inside Create Appointment screen is always 12:00 AM

The Android and iOS versions of the control support multiple and range selections. We should consider embedding such features in the Xamarin.Forms control as well.

- Android Range Selection: https://docs.telerik.com/devtools/xamarin/nativecontrols/android/calendar/calendar-selection

- iOS Range Selection: https://docs.telerik.com/devtools/xamarin/nativecontrols/ios/calendar/selection

Add pinch/zoom support to the RadCalendar control.

Enable grouping the appointments in the view according to their assigned resources

Provide the option to assign resources to appointments, so users could associate additional information to each appointment from a list with available options.

Available in the R3 2018 SP release.

When the phone language and region are set to "Russian", for example, first day of week should be Monday. Currently it stays Sunday on iOS.

By default, the RadCalendar in DayView mode starts at midnight which is not very intuitive for all scenarios. The native controls expose APIs to control the starting time so we can consider exposing StartTime/EndTime properties for the users to control.

Ref# 1106424. We are using Kendo Scheduler in our Web application to show the recurring appointments. Similarly, We need the Recurring appointments to the RadCalendar for Xamarin.Forms in Mobile to aligned with Android and IOS.   

When in MonthView, you're navigating to WeekView on CellTap event, and DisplayDate and SelectedDate are bound to the same value, DisplayDate is not updated on iOS (works properly on Android)

Hello Telerik Team,

I would like to report a bug I found on Android (not iOS).

If you use a RadCalendar inside a content page which is inside a TabbedPage, you can't swipe on the RadCalendar when it is in ViewMode=Week.

You have to draw a diagonal to make it works otherwise, the swipe (on the RadCalendar) is handled by the TabbedPage and it changes the current page being displayed.

 

If the RadCalendar ViewMode is set in MultiDay, the Swipe is well handled by the RadCalendar (instead of the TabbedPage).

 

Expected behavior : swiping on the RadCalendar in ViewMode=Week should change the displayed week (like it does in ViewMode=MultiDay).

Current Behavior : swiping on the RadCalendar in ViewMode=Week should change the selected page of the TabbedPage.

 

Why I think it is a bug : in ViewMode=MultiDay, the swipe isn't handled the same way : it actually change the displayed day and doesn't change the current page of the TabbedPage control.

PS : if the RadCalendar ViewMode is set to Month, the swipe to change the displayed month is from top to bottom or bottom to top unlike the Week mode which handle swipe from right to left or left to right.

 

I wish you a happy new year and a lot of bug fix with a lot of new feature released :)

Hi!

I've tried your TKCalendar and it looks really good. But unfortunately, there is an issue on iOS(Xamarin). I set MaxDate = DateTime.Today and SelectionMode == Range. When I tap on date grater than today they don't selected, as expected. But when I select dates by drag gesture I can select every days in month.The worst thing is that it seems that there is no way to turn off drag selection on iOS in Range selection mode. I could provide you with any files if it's necessary. 

Available in the R3 2018 SP release.

After changing the calendar's view mode on Xamarin.Forms on iOS from month to year and subsequently returning to month using the TryNavigateToUpperView and TryNavigateToLowerView calendar methods, the header with day names does not get displayed anymore.

We are using "UI for Xamarin R1 2017".
