  4. NullReferenceException on GridDateTimeColumn's Calendar popup

NullReferenceException on GridDateTimeColumn's Calendar popup

Hello

I had a problem with GridDateTimeColumn's calendar editor.

I can popup it ones and set the day. After that I press on the button opens a calendar again and get the following NullReferenceException:
System.NullReferenceException
   в Syncfusion.Windows.Controls.DateTimeHelper.CompareYearMonth(DateTime selectedDate, DateTime dateTime, Calendar calendar)
   в Syncfusion.Windows.Controls.SelectedDatesCollection.InsertItem(Int32 index, DateTime item)
   в System.Collections.ObjectModel.Collection`1.Add(T item)
   в Syncfusion.Windows.Controls.Calendar.OnSelectedDateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
   в System.Windows.DependencyObject.OnPropertyChanged(DependencyPropertyChangedEventArgs e)
   в System.Windows.FrameworkElement.OnPropertyChanged(DependencyPropertyChangedEventArgs e)
   в System.Windows.DependencyObject.NotifyPropertyChange(DependencyPropertyChangedEventArgs args)
   в System.Windows.DependencyObject.UpdateEffectiveValue(EntryIndex entryIndex, DependencyProperty dp, PropertyMetadata metadata, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, Boolean coerceWithDeferredReference, Boolean coerceWithCurrentValue, OperationType operationType)
   в System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata 


I tried different options: change UpdateTrigger, change MappingProperty on not nullable, change Pattern e.t.c.

Could you help me handle this?

Hi Vladimir,

Sorry for the inconvenience.

We were able to reproduce the "NullReferenceException while opening Calendar in DateTimeEdit control" issue only when we apply style through SfSkinManager. This issue had been fixed in our latest version [14.1.0.41]. So could you please upgrade to our latest version in order to get the issue fixed?

Regards,
Durga S.

I have completed the update. After the upgrade I get the same result in Syncfusion.Shared.Wpf, Version=14.1450.0.41

I have noticed that exception thrown is not really оn second calendar popup but on second calendar popup after value selected. If i use some default value i catch echeption on first popup.

Last rethrow exception is
System.NullReferenceException was unhandled
  HResult=-2147467261
  Message=Object reference not set to an instance of an object.
