Reply To: onCellUpdate

Hi Fabio,
Please, refer below to a sample implementation of the onCellUpdate callback function. It provides information about old and new cell value, the cell that is edited and also a confirm callback function which you may use to cancel the changes. In the example, when “test” is entered, the value is not saved, otherwise it is saved after editing.

Smart('#grid', class {
    get properties() {
        return {
          onCellUpdate: function(cell, oldValue, newValue, confirm) {
            oldValue = cell.value;
            alert(cell.row.id + "/" + cell.column.dataField);
            if (newValue === "test") {
              confirm(false);
            }
            else {
              confirm(true);
            }
          },
            dataSource: new Smart.DataAdapter(
			{
			    dataSource: generateData(1000),
			    dataFields:
				[
					'id: number',
					'firstName: string',
					'lastName: string',
					'productName: string',
                    'available: bool',
					'quantity: number',
					'price: number',
					'total: number'
				]
			}),
            editing: {
                enabled: true,
                mode: 'cell'
            },
            columns: [
			{
			    label: 'First Name', dataField: 'firstName'
			},
			{ label: 'Last Name', dataField: 'lastName' },
			{ label: 'Product', dataField: 'productName' },
			{ label: 'Available', dataField: 'available', template: 'checkBox', editor: 'checkBox' },
			{ label: 'Quantity', dataField: 'quantity', editor: 'numberInput' },
			{ label: 'Unit Price', dataField: 'price', editor: 'numberInput', cellsFormat: 'c2' }
            ]
        }
    }
});

Hope this helps.
Regards,
Peter
