Sorting in React Gantt component

Sorting enables you to sort data in the ascending or descending order. To sort a column, click the column header.

To sort multiple columns, press and hold the CTRL key and click the column header. You can clear sorting of any one of the multi-sorted columns by pressing and holding the SHIFT key and clicking the specific column header.

To enable sorting in the Gantt component, set the allowSorting property to true. Sorting options can be configured through the sortSettings property.

To sort, inject the Sort module into the Gantt component.

  • Gantt columns are sorted in the ascending order. If you click the already sorted column, the sort direction toggles.
  • To disable sorting for a particular column, set the columns.allowSorting property to false.

Sorting column on Gantt initialization

The Gantt component can be rendered with sorted columns initially, and this can be achieved by using the sortSettings property. You can add columns that are sorted initially in the sortSettings.columns collection defined with field and direction properties. The following code example shows how to add the sorted column to Gantt initialization.

Sorting events

During the sort action, the Gantt component triggers two events. The actionBegin event triggers before the sort action starts, and the actionComplete event triggers after the sort action is completed.
