Not an easy way...

You can have multiple RadioGroup controls with only one element each and a handler where you uncheck the other elements when you check one element.

I can’t recall if that’s even possible or if I used a checkbox to do this some years back

In the handler you’d do like this:

Sub DLGHandler_RadiogroupClicked

Dim nCtrl, i As Integer

   nCtrl = TriggerControl()

   For i = 1 to 5

     If (BASE_CONTROL_ID + i) <> nCtrl Then

        Alter Control (BASE_CONTROL_ID + i) Value 0

     End If

  Next

End Sub

Lol that's what I was thinking as well however I was hoping, as it turns out, beyond hope :) If I select one how do I disable/gray out others?

Peter I didn't click the "More..." and missed your complete answer. Please forgive me for this oversight and disregard my follow-up question. Thank you for your reply. I will see what I can do to get this option working.

Cheers, Martin

No worries, Martin 😊
