In Xamarin Forms.
When I call Calendar.ScrollAppointmentIntoView(theItem); in Android it works fine.
In iOS when the same call is made, the calendar scrolls about 1 pixel, then stops.
I put the call into a timer just to make sure it's there.
Device.StartTimer(TimeSpan.FromMilliseconds(3000), () =>
{ Device.BeginInvokeOnMainThread(() => { Calendar.ScrollAppointmentIntoView(theItem); });
return false; // True = Repeat again, False = Stop the timer
});
If there is an all-day appointment at a certain date, navigating to a different date through the week navigation in DayView and going back to the previous date, it will not always show the all-day item.
The RadCalendar DayView.EventView get stuck in a shifted position. This only occurs on iOS.
Steps to reproduce:
1. Load calendar.
2. Slowly slide the event view (lower portion) either right or left until the time labels (1am, 2am, etc.) are no longer in their starting positions.
3. Without releasing the scroll, tap the button to change the view to Month view mode.
4. Tap the button to change back to Day view mode.
5. Observe that the entire events view is still shifted and will remain so until the RadCalendar control is destroyed and a new one is created.
Attached are pictures showing the correct view and the incorrect view. Also, a sample project is attached that can be used to replicate this issue.
I have attempted to use a custom renderer to manually reset the events view, but nothing seems to work.
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.

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". Available in the R3 2018 SP release.
