I have a FutureQuery and a sortexpression like
var sortOn = sortSpec.PropertyName;
var param = Expression.Parameter(typeof(TestPieceDto), "tp");
var parts = sortOn.Split('.');
Expression parent = param;
foreach (var part in parts)
{
parent = Expression.Property(parent, part);
}
var sortExpression = Expression.Lambda<Func<TestPieceDto,
DateTime?>>(parent, param);
var test = futureQuery.OrderByDescending(sortExpression);
I get the following error:
Unable to cast object of type
'DataAccess.NHibernate.Linq.FutureQuery`1[Measurement.Model.Test.TestPieceDto]'
to type
'System.Linq.IOrderedQueryable`1[Measurement.Model.Test.TestPieceDto]'.
Is OrderBy supported on FutureQuery ? If so, then how do we do it ? Any
examples ? All I see in the internet is all about OrderBy in linq
statements and IQueryables on direct property access. In my case, I want to
OrderBy based on a *PropertyName string in runtime*.
