Unselects all selected records in the grid.
selectNone()
Returns undefined.

#### Description

Unselects all records in the .records array and refreshes them on the screen. The record is identified by the .recid property, which is a required property for each record object. Some records might be not shown, but they will still be unselected. For example, if you have a local data source and in the list you see only first page, .selectNone() will still unselect all records.
If you have grid defined in the following way: $('#grid').w2grid({ name : 'grid', columns: [ { field: 'recid', caption: 'ID', size: '50px' }, { field: 'lname', caption: 'Last Name', size: '30%' }, { field: 'fname', caption: 'First Name', size: '30%' }, { field: 'email', caption: 'Email', size: '40%' }, { field: 'sdate', caption: 'Start Date', size: '120px' }, { field: 'sdate', caption: 'End Date', size: '120px' } ], 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' } ] }); You can unselect all selected records: w2ui['grid'].selectNone(); There are two events related to selection of records: onSelect and onUnselect. Calling .selectNone will trigger onUnselect event for each record it unselects.
