Sorting
The Kendo UI Gantt for Angular enables you to sort single or multiple data fields.
Getting Started
To enable sorting, set the sortable option of the Gantt to true.
Clicking a column header sorts the content by a column field. A second click toggles the sort direction; a third one reverts to the unsorted state.
Sorting by Multiple Fields
The Gantt supports sorting by several fields. The Gantt indicates displays a number next to the sorting indicator to indicate the sorting order.
To enable multiple-column sorting, set the sortable option to a SortSettings object which contains { mode: 'multiple' }.
Setting the Initial Sort Order
To set the initial sorting configuration, bind the sort property of the TreeList to a collection of sort descriptors. For more information on how to process data collections, refer to the article on the process helpers for bulk data operations.
You can set the sorting direction of each field to ascending or descending by configuring the dir property of the SortDescriptor to asc or desc respectively. If dir is not set, the descriptor will not be processed.
The following example demonstrates how to set a sortable Gantt with initially applied sorting configuration.
Disabling the Unsorted State
The Gantt allows the user to remove a field from the sort order after cycling the sort direction. To disable this behavior and ensure that the fields are always sorted, set the sortable option to a SortSettings object which contains { allowUnsort: false }
