Hi Tyson,
Thanks for contacting Syncfusion support.
Currently we don’t have support to calculate and highlight the
critical path internally. It can be done only if you provide the collection which
contains the critical tasks in GanttControl.HighlightedItems in prior.However
we logged a feature report regarding this and will let you know once this
feature got implemented.
Please refer the below UG link to know more about
Highlighting task.

Please let us know if you need any other assistance.
Regards,
