React Tree List - Batch Editing
You can use batch edit mode to defer saving multiple cell changes. Changes are stored in a buffer and can be discarded before a user clicks the Save button.

To enable batch edit mode, configure the following properties:
- Set editing.mode to "batch".
- Assign true to the editing object's allowUpdating, allowAdding, and allowDeleting properties.
This demo also shows how to populate cells of a new row with default values. The values are assigned within the onInitNewRow event handler.
If data is stored on a server, the TreeList sends multiple requests to save edited objects - one request per object (this is because most servers only process one edit operation at a time). If your server supports batch update, you can configure the TreeList to save all changes with a single request. Refer to the following demo for more information: DataGrid: Batch Update Request.
