another idea is use VBA, I've updated the byundt's code.
It's not possible to show immediately the autofill, but you can type some characters and when you play enter the code check the list and if is one match, autofill the data, otherwise ask user if validate the missing name and add it to the list o delete the last value entered.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cel As Range, match1 As Range, match2 As Range, rg As Range, targ As Range
Set targ = Intersect(Target, Range("C:C")) 'Watch the cells in column C
Set sh = Worksheets("registry") 'the sheet2 where you have the list of names
Set rg = sh.Range("A2", "A" & sh.Range("A1").End(xlDown).Row)
If targ Is Nothing Then Exit Sub
Application.ScreenUpdating = False
Application.EnableEvents = False
On Error GoTo errhandler
For Each cel In targ
If Not IsError(cel) Then
If cel <> "" And cel <> " " And Right(cel, 1) <> Chr(10) Then
Set match1 = Nothing
Set match1 = rg.Find(cel & "*", lookat:=xlWhole, MatchCase:=False)
If Not match1 Is Nothing Then
Set match2 = rg.FindNext(after:=match1)
If match2.Address = match1.Address Then
cel = match1
Else
cel.Activate
Application.SendKeys ("{F2}")
End If
Else 'No matches found. The value will be added of the end of range list
msg = "The value """ & Target & """ is not in list, " & vbCrLf & "do you whant to add this item??"
response = MsgBox(msg, 4, "Update list")
If response = 6 Then
sh.Range("A" & sh.Range("A1").End(xlDown).Row + 1) = Target
Else
Range(Target.Address) = ""
End If
End If
Else
If cel <> "" And Right(cel, 1) = Chr(10) Then cel = Left(cel, Len(cel) - 1)
End If
End If
Next cel
errhandler: Application.EnableEvents = True
On Error GoTo 0
Application.ScreenUpdating = True
End Sub
