Batch Editing in ASP.NET CORE Tree Grid Component

21 Dec 20222 minutes to read

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