SubSelects in LINQ

-
What a challenge I was facing trying to figure out how to solve this problem in LINQ.. but i did it .. and am sharing.

SQL query:
Select Distinct 
o.ConceptCode,
u.firstname,
u.lastname,
(select count(*) from callLead where calldate ='2014-09-02'  and conceptcode=O.conceptcode and userid=O.userid) 'DailyTotal'
,(select count(*) from callLead where calldate between '2014-09-01'  and '2014-09-05' and conceptcode=O.conceptcode and userid=O.userid) 'WTD'
,(select count(*) from callLead where datepart(m,calldate)=9 and conceptcode=O.conceptcode and userid=O.userid) 'MTD'
,(select count(*) from callLead where datepart(yyyy,calldate)=2014 and conceptcode=O.conceptcode and userid=O.userid) 'YTD'
from callLead Ojoin users u on o.userid=u.userid

The LINQ Conversion:

The LINQ version is much prettier actually
 var rptSummary = (from e in SalesEntities.CallLeads
                            join j in SalesEntities.Users on e.UserID equals j.UserID
                              group e by new{  e.ConceptCode,e.UserID,j.FirstName,j.LastName}  into g
                         
                           select new
                             {
                                 Concept = g.Key.ConceptCode,
                                 UserID = g.Key.UserID,
                                 FirstName = g.Key.FirstName,
                                 LastName = g.Key.LastName,
                                 DailyTotal = g.Count(e=>e.CallDate == datesent),
                                 WTD = g.Count(e => e.CallDate >= firstdayofweek && e.CallDate <= lastdayofweek),
                                 MTD = g.Count(e => e.CallDate.Month == mo),
                                 YTD = g.Count(e => e.CallDate.Year == yr)

                             }).OrderByDescending(e => e.Concept);

Sorting Ascending and Descending

Toggling the direction of your datagrid sort is easy using a session to remember which direction you sorted last.   You will want to declare an empty string in the top of your page       Dim SortField As String Then on your sort command add this logic - Example of entire command Private Sub dgTaskExceptions_SortCommand( ByVal source As Object , ByVal e As System.Web.UI.WebControls.DataGridSortCommandEventArgs) Handles dgTaskExceptions.SortCommand     SortField = e.SortExpression If Session( "toggle" ) = True Then SortField += " DESC" Session( "toggle" ) = False Else SortField += " Asc" Session( "toggle" ) = True End If Dim orderstring As String = SortField 'REBIND dgTaskExceptions.DataSource = POTracking_Data.tracking.getSampleTasks(orderstring) dgTaskExceptions.DataBind() End Sub   In my datalayer I add this logic to my query and pass in an OPTIONAL value Dim orderbyString As String = String .Empt

Linq Query Syntax vs Method Syntax
