Hi Jose,

Thank you for the logged feature request. Indeed, at the moment there isn't such example demonstrating the required batch editing functionality.

Let me provide a brief guideline as to how such functionality can be achieved. Generally, in the TreeList editing examples of our documentation like the following one a request is sent on each data operation such as adding or editing when the save button is clicked:

https://www.telerik.com/kendo-angular-ui/components/treelist/editing/reactive-forms/

What could be done in order to achieve a batch editing approach is instead of sending a remote request for each action (as soon as the save button is clicked) to store these in an array. Then there can be a separate "Save changes" button placed in the toolbar template of the TreeList and when it is clicked all actions that have been previously saved in the array can be implemented by sending the respective server requests. Such similar approach is demonstrated for the Kendo UI for Angular Grid at the following article:

https://www.telerik.com/kendo-angular-ui/components/grid/editing/in-cell-editing/

I hope the provided information helps. We will track the demand for this feature request and consider providing an example accordingly.
