Excel VBA - open a DataValidation dropdown

Posted on 2016-11-22
Last Modified: 2016-12-01
I have a cell which gets a DataValidation list when a button is clicked. See attached.

I'd like to make the List dropdown end up opened after the DataValidation is created in the cell. I understand it requires 'Send Keys'. Can someone please show me how it's done?

The keyboard shortcut for opening a dropdown is Alt + Down arrow.

SendKeys ("%{Down}")

When I do this nothing happens (having disabled the Worksheet_Change in the example)

Sub FillTheDropdown()
    With Selection.Validation
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
        xlBetween, Formula1:="Tom, Dick, Harry"
        .IgnoreBlank = True
        .InCellDropdown = True
        .InputTitle = ""
        .ErrorTitle = ""
        .InputMessage = ""
        .ErrorMessage = ""
        .ShowInput = True
        .ShowError = True
    End With
    'open the InCellDropdown
        Application.SendKeys ("%{DOWN}")

End Sub

Open in new window

Shouldn't that fill the InCell DataValidation list AND leave it 'Open'?

Just that script on its own works for me, I guess it must be something to do with the fact that you have disabled Worksheet_Change event.

Try adding

Open in new window

in a line before the SendKeys

DoEvents is not needed, but use the Selection_Change event, instead of the Change event
Then select the cell and the list is shown.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If Target = Range("H16") Then
    End If
End Sub

Open in new window

I think my problem was, the code was in a Module instead of the Sheet Module.
I have since decided not to use SendKeys as it is known to be unreliable.
