Following the text till Chapter 12 Section 16.
On the codeBehind page for AddEditReview.aspx.vb

Protected Sub DetailsView1_ItemInserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertedEvent Args) Handles DetailsView1.ItemInserted
endediting()
End Sub

Get an error referring to the Endediting saying it is not declared? It is not found in intellisense. can not find reference to this anywhere. Can someone please offer some insight. Cheers

OK hold your horses, I've found the solution by reading a bit further on. Sorry for any inconvenience, guess its time for a break, Thanks.
