excel dropdown with address as result

Posted by: admin May 14, 2020 Leave a comment

Questions:

A normal data validation dropdown in Excel results in the selected value being put into the cell. In my case though, I am referencing another list in my sheet whose elements can change. My goal is to make those changes apply to already selected dropdown items.

Example:
Referenced list in dropdown (sheet “List”):

  • A
  • B
  • C

User selects A from the dropdown in sheet “Selection”:

  • A

Now the user changes A to Y in sheet “List”:

  • Y
  • B
  • C

The user’s selection in sheet “Selection” still shows A, but it should now show Y:

  • A

Is this possible in any way? Can I e.g. make the dropdown result in an address to the value, instead of the value itself?

Thanks!

How to&Answers:

There unfortunately isn’t any way to do this with a formula or build-in function (that I’m aware of)

Here is something simple you could apply and work with:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target(1, 1), Range("A1:A3")) Is Nothing Then
        ActiveWorkbook.Sheets("Selection").Range("A1").Value = Target(1, 1)
    End If
End Sub

Assuming Range("A1:A3") is the list you are refering to. Paste this under your List sheet.

Answer:

Drop Down feat. Worksheet Change Event

  • To ‘copy’ your setup, in worksheet List I have created a name
    Drop1 which refers to the column range containing the values. Then
    I have created a Validation Drop Down in B2 in worksheet
    Selection and chose the name (Drop1) as the list.
  • Change the constants (Const) to fit your needs.

    vntVal = rng
    vntNew = rngList
    Nor = UBound(vntList)

    For i = 1 To Nor
        If vntList(i, 1) = vntVal Then
            If vntVal <> vntNew(i, 1) Then
                rng = vntNew(i, 1)
            End If
            Exit For
