Critical Error when we try to move around an event in a RadScheduleView

[David]

Hi

  We get this a Critical Error when we try to move around an event in a RadScheduleView:

 

System.NotSupportedException: Specified method is not supported.
   at Telerik.Windows.Controls.DraggedAppointmentsToLocalizedStringConverter.Convert(Object value, Type targetType, Object parameter, CultureInfo culture)
   at System.Windows.Data.BindingExpression.TransferValue(Object newValue, Boolean isASubPropertyChange)
   at System.Windows.Data.BindingExpression.Activate(Object item)
   at System.Windows.Data.BindingExpression.AttachToContext(AttachAttempt attempt)
   at System.Windows.Data.BindingExpression.MS.Internal.Data.IDataBindEngineClient.AttachToContext(Boolean lastChance)
   at MS.Internal.Data.DataBindEngine.Task.Run(Boolean lastChance)
   at MS.Internal.Data.DataBindEngine.Run(Object arg)
   at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

 

  Currently we use Telerik version 2018.3.911.45 (Runtime Version V4.0.3.319).

  How can we fix this error?

Thank You,

Dave

Hello David,

Thank you for the provided stack trace but still, I will need more information so I can better understand your implementation.

Since it appears that there are some customizations applied to the RadScheduleView, may I ask you to elaborate more on which event you have subscribed for? May I kindly ask you to isolate the problem in a sample project and provide some steps which I can follow in order to reproduce the scenario on my end? This way I will be able to investigate it and further assist you.
