How can I achieve same validation features in my two custom date fields columns like we have in default fields StartDate & EndDate in angular Gantt chart Dialog/inline Editing?
For example: By default Startdate & Enddate of a task will be automatically validated(like Enddate can not be greater than Startdate ) in angular Gantt chart Dialog/inline editing by default.
So I want this same feature in my other two custom date fields(CustomStartDate1 & CustomEndDate2).
