You can use <code>ICriteria</code> and manipulate the load through <code>NHibernate.ICriteria.SetFetchMode(string, NHibernate.FetchMode)</code>. Example: DetailEnt.cs: <pre><code>using System; using System.Collections.Generic; using System.Text; namespace FetchTest { public class DetailEnt { private Int32? id; /// <summary> /// Entity key /// </summary> public virtual Int32? Id { get { return id; } set { id = value; } } private String description; /// <summary> /// Description /// </summary> public virtual String Description { get { return description; } set { description = value; } } private MasterEnt rIMaster; /// <summary> /// Gets or sets the RI master. /// </summary> /// <value> /// The RI master. /// </value> public virtual MasterEnt RIMaster { get { return rIMaster; } set { rIMaster = value; } } } } </code></pre> MasterEnt.cs: <pre><code>using System; using System.Collections.Generic; using System.Text; namespace FetchTest { public class MasterEnt { private Int32? id; /// <summary> /// Entity key /// </summary> public virtual Int32? Id { get { return id; } set { id = value; } } private String description; /// <summary> /// Description /// </summary> public virtual String Description { get { return description; } set { description = value; } } private ICollection<DetailEnt> detailEntList; /// <summary> /// <see cref="RIDetailEnt"/> one-to-many relationship. /// </summary> public virtual ICollection<DetailEnt> DetailEntList { get { return detailEntList; } set { detailEntList = value; } } } } </code></pre> Forcing eager load at runtime: <pre><code>NHibernate.ISession ss = GetSessionFromSomeWhere(); NHibernate.ICriteria crt = ss.CreateCriteria<MasterEnt>(); crt .Add(NHibernate.Criterion.Expression.IdEq(17)) //here is "force eager load at runtime" .SetFetchMode("DetailEntList", NHibernate.FetchMode.Join); MasterEnt mEnt = crt.UniqueResult<MasterEnt>(); </code></pre> In this case I used "hbm". But the logic should be the same. <h2>EDITED:</h2> With "NHibernate 2.1.2" and "NHibernate.Linq" <pre><code>INHibernateQueryable<MasterEnt> nhq = null; IList<MasterEnt> masterList = null; nhq = (INHibernateQueryable<MasterEnt>)( from master in session.Linq<MasterEnt>() where master.Id == 2 select master); nhq.Expand("DetailEntList"); masterList = nhq.ToList<MasterEnt>(); </code></pre> with <code>QueryOver<T>Left.JoinQueryOver</code> from NHibernate 3: <pre><code>IQueryOver<MasterEnt> query = session.QueryOver<MasterEnt>() .Left.JoinQueryOver<DetailEnt>(m => m.DetailEntList) .Where(m => m.Id == 2); masterList = query.List<MasterEnt>(); </code></pre> These queries work this way independently if using "FluentNHibernate" or "hbm". I made some code for it, soon I'll post the links to the files. <h2>EDITED 2:</h2> I've posted the code on <a href="http://dl.dropbox.com/u/49510149/stackoverflow/dotnet/q_10303345_1350308.7z" rel="nofollow">q_10303345_1350308.7z</a> (runnable by NUnit). There are explanations about the dependencies in the "dependencies \ readme.txt". The dll dependencies are loaded by NuGet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
