Sorting Query Trouble

Question

Try as I might I cannot get sorting to work on my screen.
I have an child entity "orders" that shows the orders made for the parent entity when a specific parnt name is selected.
On the screen I have several tabs showing the grids for orders but none of my table or screen queries is sorting the grids properties in the order defined by a query.
I am trying to sort by a boolean "Reviewed" check box and put the ones checked in order alphabetically by string "name".
Then the ones that are not checked or null in alphabetical order. Since no query would even function for some unknow reason.
I tried just hitting the sort at the top of the "reviewed" column but it only orders them by True false null and not alphabetically.
Note too Name comes from a related table one "Name" to many "Orders".
Can you think of anything I might be doing wrong?

I think you are on the right track here. I want to edit the child entity manually but I don't know how. I went to the edit query for the child entity on the screen but there is no option to add code to manually sort or filter for a screen query in VS LS
2012. Ideally I would like to sort all instances of the grid control by Monogram or MonogramC(a calculated field) AND by Reviewed(a boolean) OR just filter the specific Grid under one of the tabs the Grid is named MedicationOrderDetails5.
How do I do this I am not sure about even the code to use I have thought of adding the following to the screen code. How would you code something like this?
using System;
using System.Linq;
using System.IO;
using System.IO.IsolatedStorage;
using System.Collections.Generic;
using Microsoft.LightSwitch;
using Microsoft.LightSwitch.Framework.Client;
using Microsoft.LightSwitch.Presentation;
using Microsoft.LightSwitch.Presentation.Extensions;
//added to alow OLE DB data set code
using System.Data;
//using System.Data.OleDb;
//added for Process Start statement
using System.Diagnostics;
using System.Linq.Expressions;
namespace LightSwitchApplication
public partial class TimesAndMARs
partial void TimesAndMARs_InitializeDataWorkspace(List<IDataService> saveChangesTo)
// Write your code here.
//MedicationOrderDetails5
partial void Reviewed_Filter(ref Expression<Func<MedicationOrderDetail, bool>> filter)
filter = e => e.Reviewed != true;
partial void OrderedByMonoramCalculatedField_PreprocessQuery
(short? MonogramC, ref IQueryable<MedicationOrderDetail> query)
query = (from myOrder in query
where myOrder.MonogramC.Count() > 0
orderby myOrder.MonogramC ascending
select myOrder);
