Whene i try to change Syncfusion.Windows.Controls.Gantt.ScheduleType property from a button
GanntPanel.ScheduleType = Syncfusion.Windows.Controls.Gantt.ScheduleType.MonthWithHours;
i recived this error:
An unhandled exception of type 'System.ArgumentException' occurred in WindowsBase.dll
Additional information: '-960' non è un valore valido per la proprietà 'Width'.
The same if i set the value at designtime. If i set value at "DayWithHours" it works.
Why?
