    DataView view = new DataView(table);
    view.AllowNew = true;
    DataRowView rowView = view.AddNew();
    rowView["ProductName"] = "New Product Name";
}

Private Sub AddNew()
    Dim table As New DataTable()

    ' Not shown: code to populate DataTable.

    Dim view As New DataView(table)
    view.AllowNew = True
    Dim rowView As DataRowView
    rowView = view.AddNew
    rowView("ProductName") = "New Product Name"
End Sub
