Question

Is there a way to remove/undo .SetMaxResults() / .SetFirstResults() from a already constructed DetachedCriteria?

Can it be done without changing the original DetachedCriteria?

Answer 1

yes you can remove/undo this by setting its value to “-1”, nHibernate internally uses the static value NHibernate.Engine.RowSelection.NoValue

criteria.SetMaxResults(NHibernate.Engine.RowSelection.NoValue);
criteria.SetFirstResult(NHibernate.Engine.RowSelection.NoValue);

if you want to keep your original DetachedCriteria you need to create a clone before changing .SetMaxResults / .SetFirstResult

 DetachedCriteria clonedCriteria = NHibernate.CriteriaTransformer.Clone(originalCriteria)
                 .SetMaxResults(NHibernate.Engine.RowSelection.NoValue)
                 .SetFirstResult(NHibernate.Engine.RowSelection.NoValue);
