"I'm curious, though, why you want to use the ObjectDataSource" - why not?

I'm surprised you got that far, since the ObjectDataSource does not generally handle anonymous projections or projections into a type well.   Since you did get this far, removing the orderby from your query and instead defining a SortDescriptor should get you past the problem.
 
I'm curious, though, why you want to use the ObjectDataSource.  If you don't need paging, and also apparently not grouping or filtering, it would probably be much easier to just load the query results directly into your grid and not bother with the ODS in the middle.

Exception text like: "There is no 'ThenBy' method in System.Linq.Queriable that can deal with same arguments.

ProblemDetails:

//resiltFileDds is a ObjectDataSource: <ib:ObjectDataSource x:Name="infileDds" AutoLoad="False" PageSize="65000" LoadSize="65000"/>

  resiltFileDds.Query = (from resf in _dbCtx.ServiceTaskResultFileTemp
                                  join fd in _dbCtx.FileData on resf.FileDataId equals fd.Oid
                                  where fd.GCRecord == null && resf.ServiceTaskId == _someId
                                  orderby resf.ServiceTaskResultFileId   //!!
                                  select new DBTaskFileInfo  //this item shared (add as link) between SL and asp.net project
                                  {
                                     .....//see in logs//
                                  }).With(QueryStrategy.DataSourceOnly);

resiltFileDds.Load(); ....



Log:

Fetch ... value(IdeaBlade.EntityModel.EntityQueryProxy`1[CivilizationWeb.Models.ServiceTaskInitialFileTemp]).Join(value(IdeaBlade.EntityModel.EntityQueryProxy`1[CivilizationWeb.Models.FileData]), inf => inf.FileDataId, fd => Convert(fd.Oid), (inf, fd) => new _IB_f__AnonymousType3`2x2127173938() {inf = inf, fd = fd}).Where(<>h__TransparentIdentifier1 => ((<>h__TransparentIdentifier1.fd.GCRecord == null) AndAlso (<>h__TransparentIdentifier1.inf.ServiceTaskId == 305))).Select(<>h__TransparentIdentifier1 => new DBTaskFileInfo() {FileName = <>h__TransparentIdentifier1.fd.FileName, Title = <>h__TransparentIdentifier1.inf.Name, Oid = <>h__TransparentIdentifier1.fd.Oid, ServiceTaskId = <>h__TransparentIdentifier1.inf.ServiceTaskInitialFileId, Date = <>h__TransparentIdentifier1.inf.Date}).OrderByDescending(ti => ti.Date).ThenBy(Param_0 => Param_0.Oid).Take(65000)
