public static class QueryOverExtensions
    public static PagedList<T> ToPagedList<T>(this IQueryOver<T, T> queryOver, int pageIndex, int pageSize)
        var rowCountQuery = queryOver.ToRowCountQuery();
        IEnumerable<T> list = queryOver.Take(pageSize).Skip((pageIndex - 1) * pageSize).Future();
        int totalCount = rowCountQuery.FutureValue<int>().Value;

        return new PagedList<T>(list, pageIndex, pageSize, totalCount);


public class TeamEmployeeRepository : Repository<TeamEmployee>, ITeamEmployeeRepository
    public PagedList<TeamEmployee> GetPagedEmployees(int pageIndex, int pageSize)
        return GetSession().QueryOver<TeamEmployee>()
            .Fetch(x => x.Employee).Eager
            .Fetch(x => x.Team).Eager
            .ToPagedList(pageIndex, pageSize);
