The DataGrid only updates the dataField (status_code in your case). If
you want to update the other fields based on the value of the
status_code field, you can listen for the itemEditEnd event and update
it there.
For example:
<DataGrid id="dg" itemEditEnd="foo()" ...
function foo() {
dg.dataProvider[dg.editedItemPosition.rowIndex].status_description = "xxx";
// xxx will be based on the value of status_code
}
