MoveToDate causes iOS to crash

[Davide Accogli]

Hi support,

in my project I use sfCalendar instead of the standard calendar of iOS (which is ugly) and Androd.

I use bindable properties to set and get the selected date to and from the sfCalendar.

I recently added a bind to the property MoveToDate alongside other properties, such as SelectedDate:

                        <sfl:SfCalendar IsVisible="{Binding IsPopupStartDate, Source={x:Reference popuplayout}}"

                                        SelectedDate="{Binding TempStartDate}" MoveToDate="{Binding TempStartDate}"

                                        MinDate="{Binding MIN_BOOKING_DATE}" MaxDate="{Binding MAX_BOOKING_DATE}" />

On iOS, as soon as the sfCalendar is shown, the app crashes, meanwhile on Android I have no problems.

If I remove MoteToDate it works on both platform, but obviously the sfCalendar doesn't move to the SelecttDate if it is not today.

I'm using SyncFusion controls version 19.4.0.56, Xamarin Forms 5.0.0.2478 and Xamarin iOS 4.0.30319.

I tried SyncFusion controls version 20.1.0.47 but the problem remains.

Any suggestions?

Thank

Hi Davide,

#Regarding SfCalendar crash when setting the MoveToDate and SelectedDate property

We could not replicate the reported scenario from our end. We have prepared the sample as per the given information and checked the sample with iPhone 8 simulator with iOS 16.1 version by binding the same date for the selected date and MoveToDate property from our side. Please refer to the tested sample and video in the attachment.

Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us back with the following details,

.

• Share the issue replicated steps or videos.

• Share the issue replicated device configuration.

It will be helpful for us to check on it and provide you with the solution as soon as possible.

I saw the code and the video.

Can you please test using SyncFusion version 19.4.0.56 instead of 21.1.35?

I was able to find the problem and a workaround for this.

If the bound DateTime object to MoveToDate has value default(DateTime), it causes a crash on iOS, meanwhile it doesn't on Android. I sorted out the problem by initializing the DateTime object to a valid date.

As often, I have a different behavior on different platforms.
