Batch Editing in JavaScript TreeGrid control

08 Feb 2023 / 1 minute to read

In Batch edit mode, when you double-click on the Tree Grid cell, then the target cell changed to edit state. You can bulk save (added, changed and deleted data in the single request) to data source by click on the toolbar’s Update button or by externally invoking the batchSave method. To enable Batch edit, set the editSettings.mode as Batch.
