Xamarin iOS SelectedDate Bug

[Andrew Jabbour]

Hello,

I'm working with SfCalendar and noticed what appears to be a bug with the SelectedDate property. When I open an appointment list for a date without closing it and select another date, this property gets updated with the correct selected date value. However, when I open a list, collapse it, THEN open another dates list, the value for the selected date property is still set to the previous date. I've replicated this bug on not only my project, but also a couple of solutions posted on earlier forms including the one attached.

Steps to replicate issue:

Step 1: Open June 22 2017

Step 2: Close June 22 2017

Step 3: Open June 11 2017, notice the appointment info from the previous date remains the same

Thank you in advance for your help.

Regards,

Andrew

Hi Andrew

Thank you for Contacting Syncfusion Support.

Based on the provided sample, we have checked your issue with “SelectedDate is not updated properly in SfCalendar on iOS”. As per the current implementation the OnInlineLoaded event will be raised before the SelectionChanged event which is an expected behavior of SfCalendar Xamarin. We have modified the sample to get TempCollection using Appointment`s Start Time (Not applicable for spanning appointments which is started and ends in different date), please find the modified sample from the below link.

Sample Link: http://www.syncfusion.com/downloads/support/forum/140196/ze/CalendarSample-530401984.zip

Code snippet to get SelectedDate Appointment details and Today Date Details:


 

 

void HandleSelectionEventHandler(object sender, SelectionChangedEventArgs args) 

            { 

                vm.Today = (sender as SfCalendar).SelectedDate.ToString("yy-MMM-dd ddd"); 

            } 

 

            void HandleDrawInlineEventHandler(object sender, InlineEventArgs args) 

            { 

                if (args.appointments == null || args.appointments.Count == 0) 

                    return; 

                // Not applicable For spanning appointments (Started From Different Date) 

                TempCollection = GetSelectedDateAppointments(args.appointments[0].StartTime); 

                if (vm.Collection != null) 

                { 

                    vm.Collection.Clear(); 

                } 

                for (int i = 0; i < TempCollection.Count; i++) 

                { 

                    vm.Collection.Add(new Model() { Subject = TempCollection[i].Subject, Start = TempCollection[i].StartTime.ToString("t"), End = TempCollection[i].EndTime.ToString("t"), Location = TempCollection[i].Location }); 

                } 

                CustomInlineView inlineView = new CustomInlineView(this) { BindingContext = vm }; 

                StackLayout stk = new StackLayout(); 

                stk.HeightRequest = 150; 

                stk.Children.Add(inlineView); 

                args.View = stk; 

            }
