19 Dec 202224 minutes to read
In this section, the list of events of the Gantt Chart component has been provided which will be triggered for appropriate Gantt Chart actions.
The events should be provided to the Gantt Chart using the GanttChartEvents component. When using events of the Gantt Chart, TValue must be provided in the GanttChartEvents component.
OnActionBegin
OnActionBegin event triggers when Gantt Chart actions such as sorting, filtering, editing etc., starts.

NOTE
We are not going to limit Gantt Chart with these events, we will be adding new events in the future based on the user requests. If the event, you are looking for is not on the list, then request here.
