Events in Blazor GanttChart Component
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.
