vb.net - Gridview doesnt allow editing if give Column Names with Select New With () -


when using following data bind gridview in vb.net work fine , can edit cells when declare columns names doesnt allow me edit cell values reason thanks

    dim bs new bindingsource       bs.datasource = (from u in threecontext.dbcontext.skechersdeliveries u.isprocessed = false select u)      bs.resetbindings(true)     dgdeliverys.datasource = bs

this example how delcare column names instead of slect u have liek below 

       select new             {              leave.id,             leave.leave_month,              leave.leave_app_date,             leave.leave_from_date, leave.leave_to_date, emp.emplname, leavetype.leavedesc, leave.leave_day             }

i using following select

ordernumber dim bs new bindingsource

    dim cfglocation int16     cfglocation = cfb.storelocation     bs.datasource = (from u in threecontext.dbcontext.r3delivery u.isprocessed = false andalso u.location = cfglocation                     select ordernumber = u.ordernumber, barcode = u.tagbarcode, qty = u.qty, processed = u.isprocessed, notdelivered = u.isdelivered)         bs.resetbindings(true)     dgdeliverys.datasource = bs      dgdeliverys.columns(0).readonly = true     dgdeliverys.columns(1).readonly = true     dgdeliverys.columns(2).readonly =true

column 3 qtry , should changedable see stop @ 2 when declare column names above can no longer double click , edit datagrid directly

i think should have....

dim bs new bindingsource   bs.datasource = (from u in threecontext.dbcontext.skechersdeliveries                   u.isprocessed = false                   select new with{.id = u.fieldthatmapstoid,                                  .leavemonth = u.fieldthatmapstoleavemonth,                                  .......                                  .leave_day = u.fieldthatmapstoleave_day})  bs.resetbindings(true) dgdeliverys.datasource = bs
