Hi beb54,
You can do it by two way.
1) When your IsStock return false then you can show ModalPopup where you can give option Yes or No to confirm user answer. Onclick of Yes call the saving code which you used to save in current code on No just hide ModalPopup so no any action will perform.

Protected Sub Save(sender As Object, e As EventArgs)

mpe.Show()
Else
' call saving method
SaveDetails()

mpe.Hide()
' call saving method
SaveDetails()
End Sub
Private Function isInStock() As Boolean
' your code based on that you can return true or false
'return true;
Return False
End Function

2) Add one link button with Onclick Event will be hidden. When your IsStock return false you can call JavaScript confirm message box based on selection yes no you can perform action.
On click of yes just call __doPostBack('<%= LinkButtonId.ClientID %>', 'OnClick'); so it will call the Onclick event of Link button which will save the rest part also add EnableEventValidation="false" in Page Directive.
