    <p>One way is to project what you do want first then serialise the result into a DTO. </p> <p>However by doing this you run into an issue where you are creating DTO's with lots of setters/getters. Wouldn't it be easier to create a simple anonymous type and serialise that instead? I have written a <a href="http://puredotnetcoder.blogspot.co.uk/2012/04/setresulttransformer-into-anonymous.html" rel="nofollow">blog post</a> that explains this. </p> <pre><code>//first create our anonymous type DTO var dto = new { Id = 0L, Source = string.Empty, Destination = string.Empty, Is301 = false }; //notice the ListAs(dto) extension method var model = Session.QueryOver&lt;CmsRedirect&gt;() .SelectList(s =&gt; s .Select(x =&gt; x.Id).WithAlias(() =&gt; dto.Id) .Select(x =&gt; x.Source).WithAlias(() =&gt; dto.Source) .Select(x =&gt; x.Destination).WithAlias(() =&gt; dto.Destination) .Select(x =&gt; x.Do301).WithAlias(() =&gt; dto.Is301) ) .Take(take).Skip(page * pageSize) .ListAs(dto); return Json(new { Total = total, List = model }, JsonRequestBehavior.AllowGet); </code></pre> <p>ListAs is a simple(ish) extension method. (credit goes to Filip Kinský)</p> <pre><code>public static class NHibernateExtensions { public static IList&lt;TRes&gt; ListAs&lt;TRes&gt;( this IQueryOver qry, TRes resultByExample) { var ctor = typeof(TRes).GetConstructors().First(); return qry.UnderlyingCriteria .SetResultTransformer( Transformers.AliasToBeanConstructor( (ConstructorInfo) ctor) ).List&lt;TRes&gt;(); } } </code></pre> <p>But be warned in my example I do not serialise children collections so you may need to handle this manually yourself.</p>

    1. COThe problem is with the children elements and that the entity itself is HUGE and if I create a dto object if I change the original object i would have to change it too

    2. COAFAIK this is only way as you have already found out by running into recursive calls with your NH Poco.

    3. COI am not sure but I bet the stack overflow is caused by bi-directional one-to-many relationhips. Can you not mark what you want to be serialized on the class level?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
