adding rows to dataset table manually after retrieving from DB

[Wokawidget]

I return a dataset from a function.
This has 3 fields.

Month, WorkHrs, ContractWrkHrs

So the data may look like:

1, 45, 234
3, 23, 98
11, 19, 101

So, the months are January, March and Novemeber.
before I pass this data to a datagrid to bind I would like to add all the other months. so the data in the dataset will be:

1, 45, 234
2, 0, 0
3, 23, 98
4, 0, 0
5, 0, 0
6, 0, 0
etc

How would I do this?
I basically want to show Jan to Dec in a grid whether they exist or not in the DB.

Here's what I have so far, and it works:

Public Function FetchDisplayAFRs(ByVal DivisionKey As Integer, ByVal OperatingUnitKey As Integer, ByVal BusinessUnitKey As Integer, ByVal Year As Integer) As DataSet
        Dim ds As System.Data.DataSet = New DataAccess.AFR(_ConnString).FetchDisplayAFRs(DivisionKey, OperatingUnitKey, BusinessUnitKey, Year)
        Dim CurrentRow As Integer
        Dim MonthNum As Integer
        For MonthNum = 1 To 12
            Dim Woof(6) As Object
            Woof(0) = DivisionKey
            Woof(1) = OperatingUnitKey
            Woof(2) = BusinessUnitKey
            Woof(3) = MonthNum
            Woof(4) = Year
            Woof(5) = 0
            Woof(6) = 0
            ds.Tables.Item(0).Rows.Add(Woof)
        Next
        Return ds
    End Function

Hope that helps.
