[RESOLVED] access a DataTable which created at runtime

[iRoN_RoCK]

Hello guys,
I created a Datatable at runtime, added data to it succesfully but now i cant access it. For example, I can't filter by nationality

Public DtPlayers As New DataTable("PlayerNames")

Private Sub frmMain_Load(...)
 Do Until cnt=playerCount
   ...
   DtPlayers.Rows.Add(New Object() {cnt, PlID, PlName, vbNullString, _
   PlAge, PlNationality,  PlHeight, PlWeight, PlPosition})
   cnt=cnt+1
 Loop
end sub   

Private Sub TestGrid_ColumnHeaderMouseClick(...)
        Dim myQuery = From Player In DtPlayers _
                    Where _(what should i add here?)_ = "Turkey" _
                    Select Player
    End Sub

Thanks in advance,
