dhtmlxGrid provides users with the ability to interactively undo and redo editing operations performed on data items. But note, modifications caused by API calls cannot be undone.
The stated functionality requires PRO version of the dhtmlxGrid (or DHTMLX Suite) package.
An operation can be undone only when a user has performed at least one edit operation. The redo command is unavailable unless you have used the undo command.
