Thank you jgravois, I did it.In the grid, add the formatter function as below.<th field="Request_Date" width="75px" formatter="formatDate">Request Date</th>Then, add the conversion function.function formatDate(value) { var inputDate = new Date(value); return dojo.date.locale.format(inputDate, { selector: 'date', datePattern: 'MM/dd/yyyy' }); }
