Called when user changes an editable records but it restores to its original value. You can add event listener during the object creation: let grid = new w2grid({ name : 'grid', show : { toolbar : true, toolbarAdd : true }, columns: [ { field: 'recid', text: 'ID', size: '50px' }, { field: 'lname', text: 'Last Name', size: '30%', editable: { type: 'text' } }, { field: 'fname', text: 'First Name', size: '30%', editable: { type: 'text' } }, { field: 'email', text: 'Email', size: '40%', editable: { type: 'email' } }, { field: 'sdate', text: 'End Date', size: '120px', editable: { type: 'date' } } ], records: [ { recid: 1, fname: 'John', lname: 'doe', email: 'vitali@gmail.com', sdate: '1/3/2012' }, { recid: 2, fname: 'Stuart', lname: 'Motzart', email: 'jdoe@gmail.com', sdate: '2/4/2012' }, { recid: 3, fname: 'Jin', lname: 'Franson', email: '--', sdate: '4/23/2012' }, { recid: 4, fname: 'Susan', lname: 'Ottie', email: 'jdoe@gmail.com', sdate: '5/3/2012' }, { recid: 5, fname: 'Kelly', lname: 'Silver', email: 'jdoe@gmail.com', sdate: '4/3/2012' }, { recid: 6, fname: 'Francis', lname: 'Gatos', email: 'vitali@gmail.com', sdate: '2/5/2012' } ], onRestore: function(event) { console.log(event); } }); or after the object has been created: w2ui.grid.on('restore', function(event) { console.log(event); }); The record will restore to its original value if user clicks ESC button. The event handler is called before the default action of the event is triggered. You can cancel the default action by calling event.preventDefault(). To perform an action after the event is fully processed, define event.onComplete function. See events page in utilities for more details.
