If you protect the worksheet in code, you can do it:

Option Explicit
Sub auto_open()
With Worksheets("Sheet1")
.Protect Password:="hi", _
DrawingObjects:=False, Contents:=True, Scenarios:=True, _
userinterfaceonly:=True
.EnableAutoFilter = True
End With
End Sub

(The worksheet has to have the dropdown arrows already applied.)

It needs to be reset each time you open the workbook. (excel doesn't remember
it after closing the workbook.)

But there are some things that macros can't do even with
userinterfaceonly:=true. You'd have to unprotect the sheet, do the work and
reprotect the sheet.

(you could use the workbook_open even under ThisWorkbook, too.)

If you're new to macros, you may want to read David McRitchie's intro at:
http://www.mvps.org/dmcritchie/excel/getstarted.htm

That said, worksheet protection is very weak. There's code posted here every
day/week that would unprotect the worksheet.

Hello,

I have a list in Excel 2000, the values in the list are derived from
formulas in the cells of the list. I use an autofilter to sort out the
blank cells in the list. The problem: I would like to protect the list to
keep the formulas intact, but when I protect the list the autofilter won't
function. I've tried unlocking the cell with the filter button, no good. I
tried each one of the switches on the protect (password) window, no good.

Is it possible to protect the list and keep the filter functional?

Thanks!
