I am new to KENDO UI Gantt Chart, using it for the first time, and facing lots of issues in adding new columns and calculations.
My client's requirement is to have a Duration column based on Planned Start Date and Planned End Date, column should be editable and when I change either PSD or PED duration should be updated, and vice versa that is if I update the duration my Planned End Date should also get updated accordingly.
Requesting help on this, I have attached the code.
