.NET error happening when user right clicks inside of the UltraWinSchedule control while in UltraDayView mode
posted

Hello,

Our product uses the UltraWinSchedule control.  When a user is using the UltraDayView mode and they right clicks the user will sometimes get a .NET error.  It's erratic and we are unable to recreate the issue on our end.  Have you guys heard of this issue or do you know what's causing it?  The following is the exception text from the .NET error:

System.NullReferenceException: Object reference not set to an instance of an object.
at Infragistics.Win.UltraWinSchedule.UltraDayView.RestoreAppointmentsToPreDragPositions()
at Infragistics.Win.UltraWinSchedule.UltraDayView.OnDragOperationEnded(Boolean hadStarted, Boolean canceled)
at Infragistics.Win.UltraWinSchedule.UltraDayView.Infragistics.Win.ISelectionManager.OnDragEnd(Boolean cancelled)
