DataGridView

Please sir, how can i implement the linq code below in a data bound DataGridView. My DataGridView is bound to a Dataset but I have one unbound column which I want to display the output postion from the linq code. My DataGridView look like this

Names Total score position

The Names are coming from the database, user will input the score on button click I want the linq code position result to display on the Position
column. Thanks.

What I have tried:

' Example user scores
    Dim userScores = {
        New With {.Score = 65, .Name = "Linda"},
        New With {.Score = 65, .Name = "Paul"},
        New With {.Score = 64, .Name = "John"},
        New With {.Score = 63, .Name = "Yoko"}
    }
    ' Transform user scores to a high score table
    Dim table = _
        userScores _
        .OrderByDescending(Function(user) user.Score) _
        .Select(Function(user, i) New With {.Index = i + 1, .User = user}) _
        .GroupBy(Function(row) row.User.Score) _
        .SelectMany(
            Function(group)
                Dim position = group.First().Index
                Return group.Select(
                    Function(row)
                    Return New With {.Position = position, .User = row.User}
                End Function)
            End Function)
    ' Print results
    For Each row In table
        Console.WriteLine("{0} {1} {2}", row.Position, row.User.Score, row.User.Name)
    Next
