Точнее вот так:

void selectGridLine(FormDataSource _formDataSource, int _ineNum)
{
    int     lineCountLocal;
    ;

    lineCountLocal = 0;

    while(_formDataSource.queryRun().next())
    {
        lineCountLocal++;

        if(lineCountLocal == _ineNum - 1)
        {
            _formDataSource.findRecord(_formDataSource.queryRun().get(_formDataSource.table()));
            break;
        }
    }
}
