How to write OrderByDescending and where clause in single LinQ query

Hope that helps You need to put parenthesis for you predicate i.e where clause.
Either use query syntax or lambda expression completely. The following should work:
code :
(from a in Attendances
where a.Deviceid == 1 
select a)
Attendances.Where(a =>  a.Deviceid == 1) 
.Select(a => a.UpdatedDate);
var latestDate = Attendances.Where(a =>  a.Deviceid == 1)

fixed the issue. Will look into that further Measure Measure Measure. Strip everything out to the simplest query and measure it. Then add in bits at a time until you find 'the hole.'

LINQ - How to make a linq query with left join, group by, where clause and order by in a single query

Date : March 29 2020, 07:55 AM
This might help you I have googled for four days but not found a single example which contains all three keywords in a single linq query.
code :
Dim query = (From n In tblNseFo.AsEnumerable _
                            Where n!client_id = intClientID _
                            Group Join c In tblClient _
                            On n!client_id Equals c!client_id Into cs = Group _
                            From c In cs.DefaultIfEmpty _
                            Group n, c By _
                            c!client_name, n!instrument_group_id, n!trade_date Into gs = Group _
                            Order By trade_date _
                            Select New With { _
                                .client_name = client_name, _
                                .instrument_group_id = instrument_group_id, _
                                .trade_date = trade_date, _
                                .TotBuyQty = gs.Sum(Function(x) x.n!buy_qty), _
                                .TotSellQty = gs.Sum(Function(x) x.n!sell_qty), _
                                .TotBuyVal = gs.Sum(Function(x) x.n!buy_value) + gs.Sum(Function(x) x.n!buy_brokerage), _
                                .TotSellVal = gs.Sum(Function(x) x.n!sell_value) - gs.Sum(Function(x) x.n!sell_brokerage), _
                                .ProfitLoss = (gs.Sum(Function(x) x.n!sell_value) - gs.Sum(Function(x) x.n!sell_brokerage)) - _
                                              (gs.Sum(Function(x) x.n!buy_value) + gs.Sum(Function(x) x.n!buy_brokerage))})

How to query in linq using orderbydescending?

I wish this helpful for you You're a little bit off here. First of all, if you reorder the list 4 times, the first 3 will have been a waste of time. I'm not sure what your logic is there, so I'll leave it at that. You need to rethink your filtering logic.
Secondly, the Func that you pass to OrderByDescending gets the key to order by; it doesn't perform filtering. So when you do:
code :
data = data.OrderByDescending(c => c.UploadDate >= query.startDate)
data.Where(c => c.UploadDate >= query.startDate)
    .OrderByDescending(c => c.UploadDate)

OrderByDescending before AddRange Linq Query

fixed the issue. Will look into that further The outcome of OrderBy is a new enumerable that you need to assign and evaluate. You don't do anything with the outcome.
You need this:
code :
promolist = promolist.OrderByDescending(o =>  o.packagelevel.level)
                     .ThenByDescending(o => o.totalclick)
