SMART datagrid v.1 > Classes > DataSet
Return the State of data row which is located in parameter row. 
If the row is the value beyond the range, that is, if it is less than 0 or greater than rowCount, it will throw an exception.
    var rowState;
    for (var i = 0; i < dataset.rowCount(); i++) {
        rowState = dataset.getRowState(i);
        // If row state of row is DELETED or the CREATE_AND_DELETED row exists, it will initialize the state of all rows.
        if (rowState == DataRowState.DELETED || rowState == DataRowState.CREATE_AND_DELETE) {
            dataset.clearRowStates([DataRowState.DELETED, DataRowState.CREATE_AND_DELETED], true);
            break;
        }
    }
