Hi Marc,

The only thing that will allow you to do a similar kind of thing is the DataTable.ImportRow() method. Depending on how much you have to do this sort of thing, it may or may not be helpful. It would work something like this:
    Public Sub testDatarows()
        Dim oDt As New DataTable
        oDt.Columns.Add("Field1", GetType(String))
        oDt.Columns.Add("Field2", GetType(String))
        oDt.Columns.Add("Field3", GetType(String))
        Dim odr As DataRow = oDt.NewRow
        odr("Field1") = "value 1"
        odr("Field2") = "value 2"
        odr("Field3") = "value 3"
        oDt.Rows.Add(odr)

        ' will add a new row
        oDt.ImportRow(odr)
        ' then change the newly added row
        oDt.Rows(dt.Rows.Count-1).Items("Field3") = "value 4"

        For Each odr In oDt.Rows
            Debug.Print(odr("Field1") & "- " & odr("field2") & "-" & odr("Field3"))
        Next
    End Sub
