Multiple address rows with state list based on country - ms-access

Question

I have multiple address rows with a state and country combo box. I limit the state list based on the country. It looks like
However, when I change the value of the state and this detail row loses focus, it saves and clears the value of the other state like
I have an event on the state field to set the list when it gets focus.
Private Sub cboState_GotFocus()
MsgBox ("Country: " & Me.cboCountry.value)
If Nz(Me.cboCountry, 0) = 0 Then
MsgBox "Please select a country first"
Me.cboCountry.SetFocus
Else
If Nz(Me.cboCountry.value, 0) = 0 Then
Me.cboState.RowSource = ""
Else
Me.cboState.RowSource = "SELECT id, stateCode, stateName FROM state where country_id = " & Me.cboCountry.value
End If
End If
End Sub
I tried setting 'Limit to List' to No, but it gave an error
I tried setting Column Widths to 0.001";0.3938";1.1806", but then it displayed the id field instead of the state code. Here are the current values
Column Count 3
Column Widths 0";0.3938";1.1806"
Row Source SELECT id, stateCode, stateName FROM state where country_id = [country_id]
Bound Column 1
Limit to List Yes
How can I have multiple state combo boxes, each with a different restricted list based on the country?

Answer 1

An Access combobox whose LimitToList property is set to Yes can only show values returned by the RowSource property, even if the ControlSource is set to another value.
The workaround is to put a textbox on top of the combobox (but not covering the arrow) and show the text value in the textbox, using =Dlookup("textvalue","tbl","Id = " & numericvalue) in the ControlSource property. That way you can show a value that is not in the list.
