This should give you a nudge in the right direction:

'dv is a DataView, you could use a DataSet too
For Counter As Integer = 0I To dv.Count - 1I
    If dv(Counter)("ColumnName") Is DBNull.Value Then
        'This is a null value
    End If
    If dv(Counter)("OtherColumnName") Is DBNull.Value Then
        'This is a null value
    End If
Next Counter
