Sorting in Vue TreeGrid component

24 May 2022 / 3 minutes to read

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 TreeGrid, set the allowSorting to true. Sorting options can be configured through the sortSettings.

To sort, inject the Sort module in the treegrid.

TreeGrid columns are sorted in the Ascending order. If you click the already sorted column, the sort direction toggles.

You can apply and clear sorting by invoking sortByColumn and clearSorting methods.

To disable sorting for a particular column, set the columns.allowSorting to false.

Initial sort

To sort at initial rendering, set the field and direction in the sortSettings.columns.

Sorting events

During the sort action, the treegrid component triggers two events. The actionBegin event triggers before the sort action starts, and the actionComplete event triggers after the sort action is completed. Using these events you can perform the needed actions.
