Re: Cascading Combo boxes using CASE command



Douglas,

Based on your suggestion I have designed a Table containing all information:
Countries, Cities and Colleges ( tblAll ).

The Country combo is in Main form and Cities and Colleges combo are in
Subform.
The idea is based on the country i select the appropriate cities need to
display and based on the cities I select the appropriate colleges need to
display.

I ran the following code in 'after update' of country but it did not work. I
guess the error is in addressing the combo in Subform. Please do have look at
the code below:

Private Sub Country_AfterUpdate()
On Error Resume Next
Me.[College Subform].[Form].City.RowSource = "Select tblAll.City " & _
"FROM tblAll " & _
"WHERE tblAll.Country = '" & Country.Value & "' " & _
"ORDER BY tblAll.City;"
End Sub

Note: College Subform is the control name of Subform in my Main form.

Any help?

Did you try it? Did it work?

I may be reading too much into your variable names, but if you've actually
got tables named "Tbl_London_college", "Tbl_Amsterdam_college" and
"Tbl_Sydney_college", odds are your design is incorrect.

You should have one table that contains all of the colleges, with a field
indicating the city to which the college is linked. Your RowSource would
then be a query with an appropriate WHERE clause, and you wouldn't have to
go through this machinations.

Hi Jeanette,

I have sorted that out - combo cascading from 'countries'[main form] to
'cities' [subform] based on the code u gave below.

Now I need to combo cascade 'cities' [sub form] to 'Colleges' [sub form].
Could I use the same code below as long as I indicate that 'cities' and
'colleges' are Sub Form eg:

Private Sub cboCity_AfterUpdate()
On Error Resume Next
Dim strTableName as String
Select Case cboCity.Value
Case "London"
strTableName = "Tbl_London_college"
Case "Amsterdam"
strTableName = "Tbl_Amsterdam_college"
Case "Sydney"
strTableName = "Tbl_Sydney_college"
End Select

Me.[NameOfSubformControl].Form.cboCollege.RowSource = strTableName

End Sub

Will this work?

Hi Agnelo
you need the correct syntax to 'talk' to the subform.
The name of the subform control is important.
A subform is always inside a subform control on the main form.
The name of the subform control can be, and often is, different from the
name of the subform inside it.

To talk to cboCity when it is on the subform you use syntax like this:
Me.[NameOfSubformControl].Form.cboCity
instead of just cboCity

Code something like this:

Private Sub cboCountry_AfterUpdate()
On Error Resume Next
Dim strTableName as String

Select Case cboCountry.Value
Case "France"
strTableName = "tblFrance"
Case "United Kingdom"
strTableName = "tblUnitedKingdom"
Case "United States"
strTableName = "tblUnitedStates"
End Select

Me.[NameOfSubformControl].Form.cboCity.RowSource = strTableName

End Sub

I tried setting up a cascading combo box between countries and cities
i.e
based on the country u select , you can view the appropriate cities in
the
other combo box.
I tried using CASE command in 'after update' of country combo box:

Private Sub cboCountry_AfterUpdate()
On Error Resume Next
Select Case cboCountry.Value
Case "France"
cboCity.RowSource = "tblFrance"
Case "United Kingdom"
cboCity.RowSource = "tblUnitedKingdom"
Case "United States"
cboCity.RowSource = "tblUnitedStates"
End Select
End Sub

This works fine but now I need 'cities' combo box to be in SubForm. So
based
on the option I select in Countries [on MainForm] I should get the
appropriate cities [on SubForm] by using CASE function...Any help
