SFSchedule crashes when the collection appointment collection is empty for today

[Michael]

It seems like a new problem or I haven't encountered it yet. 

When switching to the view I'm greeted with an exception...

**System.ArgumentOutOfRangeException:** 'Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index'

here is my xaml and I'm starting the view in weekView Mode. MonthviewMode works

                            ScheduleView="{Binding ViewMode}" DataSource="{Binding Items}"

                            SelectedDate="{Binding SelectedDate, Mode=TwoWay}"

                            FirstDayOfWeek="2" VisibleDatesChangedCommand="{ Binding ScheduleVisibleDatesChanged }"

                            CellTapped="Schedule_CellAppointmentTapped" 

                            ShowAppointmentsInline="false" MonthInlineAppointmentTapped="Schedule_MonthInlineAppointmentTapped" 

                          

                          

                            Grid.Row="1"

                            ViewHeaderHeight="40" HeaderHeight="40"  >

               

                   

                        FontFamily="Arial"

                        FontSize="12"  />

               

               

                   

                        DayFontFamily="Arial"

                        DayFontSize="10"

                        DateFontFamily="Arial"

                        DateFontSize="10" />

               

               

                   

                                        WorkStartHour="{Binding CourseStartHour}"

                                        WorkEndHour="{Binding CourseEndHour}">

                       

                           

                       

                   

               

               

                   

                   

                                            ShowAgendaView="true" 

                                            />

Hi Michael,    

   

Thank you for contacting Syncfusion support.   

   

We have checked the reported issue “System.ArgumentOutOfRangeException occurred while changing the ScheduleView in Schedule” and we are unable to reproduce the issue from our end. We checked by changing the ScheduleView dynamically and checked with CellTapped and MonthInlineAppointmentTapped events, it is working fine as expected. We have attached the tested sample and video for your reference.   

 

Please find the sample and video from below link.  

   

Tested Versions:   

·       Syncfusion update version 17.3.0.19   

·       Xamarin.Forms version 3.6.0.344457
