RangeSelection and SelectedDates on ios

[jens de rijcke]

Hello

I am using a SfCalendar with RangeSelection. I am using calendar.SelectedDates.Count in my code, this works fine on android and I get the amount, but when I try the exact same thing on ios it always is 0, not null but 0. It's probably a bug, can you let me know if it is? I suspect that there are simply no selected dates.

Hi Jens, 

 

Thank you for contacting Syncfusion support. 

We have checked your query “SelectedDates property of calendar not returning correct count” in Xamarin.Forms.iOS. SelectedDates property is only for the MultiSelection SelectionMode in Calendar, not for the RangeSelection. We have mentioned the same in our User Guide documentation as well,

UG link: https://help.syncfusion.com/xamarin/sfcalendar/calendar-mvvm#binding-selecteddates

Although we have considered this behavior difference “SelectedDates property gives value for RangeSelection in Android” as a defect and internally logged the defect report for the same. We will update this behavior as common (all platforms) in our upcoming releases. 

 
Your requirement of “Getting Selected Range dates and it’s count in calendar” can be achieved in two ways. Using SelectedRange property of Calendar, you can get the Start and End of the Selected Range and DateAdded property of SelectionChangedEventArgs in the SelectionChanged event of Calendar, you can get the selected dates collection within the range. Please refer the following code snippet, 

 

[C#] 

 

calendar.SelectionChanged += Calendar_SelectionChanged;            

… 

        private void Calendar_SelectionChanged(object sender, Syncfusion.SfCalendar.XForms.SelectionChangedEventArgs e) 

        { 

            // You can get the SelectedRange Start date and End date 

            var selectedRange = calendar.SelectedRange; 

            // Using this can get the selected date collection within the range 

            var selectedDateCollection = e.DateAdded; 

           // Get the selected dates count 

            var selectedDatesCount = e.DateAdded.Count; 

        } 

 
We have attached the sample for your reference,

Sample link: CalendarRangeSelection_Sample 

In SelectionChangedEventArgs of the SelectionChanged event, you can get the DateAdded, DateRemoved and NewRangeAdded values.

We hope this helps. Please let us know, if you would require any further assistance.

Hello

I solved it with the e.DateAdded. It's just weird that it behaves different while it is multiplatform. So that makes that it is unusable in my application.

Anyway, thanks.
