Cascading Combos On Continous Forms
May 12, 2006
Hi Guys,
I have two unbound cascading combo boxes on a form that limit the data for a stored field.
I am designing this as a subform to show software installed on a PC (hence the need to have a continuous form). As the manufacturer, software package and edition are already stored in my database, I am storing only the ID of the edition to limit duplicating data.
I would like to show the values in the cascading combos that relate to the edition ID stored as well as filtering the edition ID using the combo boxes (i guess a filter and a reverse lookup)
Please see attached pic. First record was entered as Microsoft Autoroute. New record for Manufacturer Frontier, change the previous records combos.
Thanks for you help
Ben

I have attached a copy of my database.

Hi!
I am trying to find a solution for this many to many relation and combos! I ve managed to do the one-to-many as the Mile-o example but i have trouble getting the same result right on many-to-many relations
as you know access needs us to create an extra table for many-to-many relations! but the example talks about the current an the previous table! how can i have 3 cascading combos with many to many relations to each other???
i also have a fourth but this one is related as one to many with the 3rd!
for more information i have:
Many Cars-to-many Categories of brands of parts
Many Categories-to-Many Brands of parts
One Brand-to-Many parts
the many parts combo is also a record selector!
In the beginning I had one table of parts with 4 foreign keys then i changed it to the current one with the previous chain of relation ending to parts with one foreign key! is this better???
Thanx! I hope I made my proble as clear as i could :)
Please Heeeeeeeeeeeeeeeeelp :) :)

Can anyone kindly help me with the attached
database. I need to synchronize 3 combo boxes.
based on the choice made in the previous box.
I have seen it done before using text fields but
not using numeric fields as in my case here and
without using queries.
I have set the RowSource for the 3 boxes on the
OpenForm event and have removed all my code
attempts.
Thanks for your help

I am new at programming in Access and I am writing a database for our church. I have 2 tables, one called “Donators” and the other “Donations”. In the Donators table I have their Last Name and First Name along with their address etc. In the Donations form I use a combo for the Last Name and a separate combo for the First Name. I did this so the person entering data doesn’t have to use a mouse but simply tab and type. Both combos are bound to the ID number. Without using a cascading combo, all First Names appear not just the ones relating to the Last Name. I checked the examples on cascading combos and tried them but without success. I could really use someone’s help. Thanks.

Hi All,
I have a query about cascading and combo boxes, which I was kindly, advised about previously. However, I’m stuck as to how to cascade using the selections from more than one combo box. Here are the tables involved
tblLine
fld LineID (PK)
LineDesc
tblMachine
MachineID
MachineDesc
tblLine_Machine
LineMachineID (PK)
LineMachineDesc
LineID (FK)
MachineID (FK)
tblCategory
DTCategoryID (PK)
DTCategoryDesc
tblDTReason
DTReasonID (PK)
DTReasonDesc
tblCat_Mach_Reason
CatReasonID (PK)
DTCategoryID (FK)
MachineID (FK)
DTReasonID (FK)
What I’m trying to do is create a form to enter downtime incidences and would like the downtime reason to be selected following a series of combo boxes. The first combo box selects the Line on which the downtime has occurred, using this, the next combo box selects the machine. I would like the category selected independently but then need the Downtime Reason selected based on the selections in the machine combo box and the category combo box. This is where I am having the problem.
I can get the machine combo box to display machines dependent on the Line selected and I can get the downtime reasons combo box to display machines dependent on either the machine selected or the category selected, but I don’t know how to get it to do it based on both.
e.g. the category may be mechanical, but there are reasons that are mechanical and specific to each machine.
Any help with this would be most appreciated.
Regards
Keji

Hi,I shall be grateful for any help.
My problem
Tables:
Cars
Customer
Invoice
TblMake
Tbl Model
I have used cascading combos for Make and Model. They work fine. I have set up tblMake as follows:
ID
Make
I have make tblModel as follows:
ID
Make
Model
I use these cascading combos on a form. The data from this form goes into the "Cars" table. I have set the "Column Bound", "Width" etc. to show the name of the car, not the number.
However, I have created a search form. This uses a SELECT...... case in the Row Source. The details of each car are shown in a unbound listbox. This select case is supposed to show "Make" and "Model", which it does, however - they are numbers!!!
Please can anyone let me know how to change it so it shows the actual names of the car.
Thank you

OK, here is the problem. I have the following tables:
Customers
Consignment
ConsignDetails
Employees
Products
Suppliers
CompanyColors
CompanySizes
and I am creating a form to view the items currently on consignment with the customer. I have the main form 'Consignment' that holds the CustomerID, ConsignID, DateStarted, Employee (SalesPerson), Inventory Interval, and Closed (Y/N)... The subform lists in datasheet view the records in form 'ConsignDetails' that have the same ConsignID. The controls on the subform are :
ProductID
UnitPrice
Quantity
Color
Size
The ProductID is selected in a combobox from all products. The UnitPrice defaults to a DLookup() from the products table based on the ProductID, but can be changed and stored. The Quantity is a manual entry field. Color and Size are both supplier-dependent fields, in other words, the supplier of the product has unique Size and/or color codes or descriptions. I have no problem creating a combobox either in the AfterUpdate event of the ProductID or in the MouseDown event of the Color or Size field to limit the drop-down list to only those Colors/Sizes from the CompanyColors / CompanySizes tables with the same SupplierID as the Product in the first control.
So far so good, but here is where I am beating my head against the wall. Every time I choose a product from a different supplier, the Color and Size controls display ONLY the items from the current Supplier, not the items from the Supplier of the Product on their individual records. I have seen ways to make the combo popluate a locked textbox, hide the combo, and display only the text, but in a data entry application the user will be primarily on the keyboard, and the solutions seem to make it almost impossible to do without using the mouse over a continuous form.
I am using Access 2002 (ver 10.6501.6735) SP3 to create an ADP using MSDE to link to SQL7 tables....
Any help will be appreciated, I have spent almost two weeks trying different approaches and may be too close to the forest to see the trees.
Thanks,
Bruce Davis

OK ive got my 2 vaguely working combos which select the surgery, and the staff.
On the same form I want a couple of tickboxes which show for example, whether a person attended the course, if they had to pay etc (all yes/no answers).
How do I get the tickbox to update? i have tried to requery it but nothing happens, it just stays as what the last thing done to it was.
SHould i be using a subform here do you think?

Heya
Ive got my combos working fine now (thanks to all you kind folk on this forum!) but now that I have opened the main form (in which the combo box form is nested), once I have selected an item in the first one, and then click on the 2nd combo, a parameter box comes up saying "Forms!Training Record!Course_title_combo" and wants a value.
I cant see why this doesnt work when the form is nested, any ideas?

Hello to all !
I have this db where i wantto include 4 and if possible 5 cascading combos where the user can select records from a table and view them in a subform which is in datasheet view.
All is going well until i try to add the 4th combo.Then when i select the 4th combos selection the subform displays nothing.
If someone could point me to the right direction i would be most thankful.
I have attached the db.
Thx for all replies :)

I have set up a form which has 2 combos.
Combo A pulls from a query which gets surgery address1, address2, and surgeryID. It displays only the first 2 fields.
Combo B gets info from a query getting staff firstname, surname, title, staffID and surgeryID, and shows the first 3 fields.
I have the following code in the afterupdate of box A (surgery_combo)
Private Sub surgery_combo_AfterUpdate()
staff_combo = 0
staff_combo.Requery
End Sub
HERE IS THE PROBLEM:
The queries seem to work fine, as box B displays the staff that work at each surgery. However on selecting a staff member, you can only SELECT the ones who have a salutation (mr/mrs etc) in the first column. And when you DO select this - the combo shows a most unhelpful "Mr" whereas I want the name there.
How do I change the column that the combo displays once selected?

Hi
I would like to be able to create a continous form that different type of inage depending on values set in a given field. I have found that if I put an image field in my table and use this idea it works ok. The problem I am getting is to change the image based on the value in the given field. To make this easier to expalin. record one is a yes or no value record two is an image value that could be image one or image 2. I tried storing the images in a seperate table. Could someone help with making this work with vb code.
Thanks Paul

I've asked this question before, but no one's answered it yet. How do I create a form where I can enter many records for projects (from tblProjects) and associated workstreams (from tblWorkstreams), so that I can select a project from a combo and then pick a workstream from a filtered list?
With help from Colm, I've been able to set up the combo's and get the filter to work, but unfortunately, the Project combo (cboProjectSelect) filters the cboWorkstreamSelect for ALL records! This means that only one project can be selected for ALL records.
The way it's been set up so far, is there is a query which lists Workstream, WorkstreamID and ProjectID, and the criteria for ProjectID in that query is: [forms]![frmTshtEntry]![frmTshtProj]![cboProjectSelect]. The cboWorkstreamSelect combo is then based on this query.
I am really stuck on this, and any help would be greatly appreciated!

I'm trying to filter a combo based on the selection in another combo.The twist is that I need the row source of both combos to include an "*", "(All)" selection, as I am using these combos to filter a listbox. When I add the Union query with "*", "(All)", the row source in the 2nd combo is ignoring the where clause.
After making a selection in the Comp combo, the Emp combo should be filtered. It works with no Union in the row source, but does not work with the Union in the row source.

Continuous forms error.
Hi,
I have a database which displays one form as a subform of another form. Originally the subform was displayed in datasheet view, but now due to changes I am trying to make to the system I want to display this subform as continuous forms. Unfortunately in datasheet view, when a record of the main form has several records (ie enough to require scrolling down the list) in the subform I get errors when scrolling through these subform records.
The error message that access is displaying is "The Value you entered isn't valid for this field. eg you have entered text in a numeric field or a number that is larger than the FieldSize setting permits."
I thought ok, maybe the subform design was duff (I am taking over a system designed by someone else) and so created a new subform, but the error still occurs with a totally fresh subform. The error occurs even when viewing the subform on its own. With a lot of records displayed on screen in the continous forms view I get numerous occurances of the abopve mentioned error message box and access eventually crashes. Yet in datasheet view everything is fine.
It's incredibly annoying as I can't fathom out what is causing the problem and how to fix it and to go about what I am doing in another way (ie without using continous forms) will mean scrapping a whole days work. I also don't like to do things a different way just because I can't get it to work the way I'd like to.
If anyone has some solutions to this problem I would be eternally grateful!
Thanks in advance!
John

I'm trying to follow Allen Browne's - Combos with Tens of Thousands of Records [URL] ....
However, I keep getting the error...
Compile Error:
Invalid use of Me keyword
(This being a new module)
That's how it shows in his code (the use of me.comboname.rowsource) but it's not working for me.

I am trying to get get 2 comboxes to refresh from one when cascading. The first combobox (Location) works, but the second one (Catches) doesn't. All I get are the Key values of the catches rather than the values...
I am wondering if it my relationship set up of if my VBA needs to be altered to accommodate the requering the two comboboxes.
Code:
Private Sub cboCategory_AfterUpdate()
Dim sCatchLocation As String
Dim sCatch As String
sCatchLocation = "SELECT [tblLocation].[Location_ID], [tblLocation].[LocationCategory_ID], [tblLocation].[Location] " & _
"FROM tblLocation " & _
[Code] .....

I think I've solved a method to have cascading comboboxes on a continous subfrom.
The after update on the first box sets the query the drives the secondbox's rowsource, and blanks out all the boxes below it. And so on.
Dim EventTP As String
EventTP = Me.cbxClass1
Me.cbxClass2.RowSource = "SELECT distinct Class2 FROM tblEventTypes WHERE (((class1)='" & EventTP & "'));"
Me.cbxClass2 = ""
Me.cbxClass3 = ""
Me.cbxClass4 = ""
All of the comboboxes are fed by one table.
Comments?

We've got an Access Database that I've edited in the past, I've got the cascading combo boxes set up so that, depending on which employee is selected, different "rate" options appear as work done. If I open the database afresh and select an employee (for example, employee 9 in Image 1 and employee 19 in image 3) the rates given to that employee are correct.
However, if the database remains open, I can't get the rates to update with the selected employee - even if the employee is clicked, rentered, etc.
Image 1: Freshly opened database, - Correct Rates
Image 2: Database remains open, - Incorrect Rates
Image 3: Freshly opened database, - Correct Rate
Image 4: Database remains open, - Incorrect Rates
I've tried to make it requery when clicked... or before the event... or on form click... or anything, but it doesn't want to know.

I have a cascading combo box that successuflyl returns data from sql server tables venue and date, when I save the record it saves the values but when I re open the record for a particular patient the combo box values are cleared and do not display patients appointment venue and date although it is saved in the database. How can I return the values in the combo boxes which were saved.

I have built several combo boxes in other DB's but haven't had this happen before. I am adapting a template DB to work for me. The form is continuous and I added a field [CategoryID], I want the [ProductID] to filter based on CategoryID choice. Pretty straight forward and it works, but the [ProductID] field will not hold the text value. It's a number field to hold the ID value, and bound column is 1(Select query is ID,ProductName,StandardCost) with ID and StandardCost column widths set to 0cm. I can choose CategoryID, the ProductID combo filters correctly, then when I proceed to the next record, the ProductID goes blank.

I have a form with various input boxes, three of which are combo boxes. These combo boxes need to affect one another. So let's call these cmb1, cmb2 & cmb3.
Hypothetically let's say:
Within cmb1 the list is A, B, C & D
If the user was to choose A, cmb2 would show the options 1, 2, 3, 4, 5 etc..
If the user was to choose B, cmb2 would show the options 2, 4, 6, 8, 10 etc..
if the user was to choose C, cmb2 would show the options 1, 3, 5, 7, 9 etc..
(So, it is possible that if the user chooses A from cmb1, cmb2 would show 1 and if the user chooses C from cmb1, cmb2 would also show 1)
Using the example in the brackets above:
If the user chose cmb1 - A then chose cmb2 - 1, cmb3 would then show the options Option1, Option2, Option3 etc..
BUT
If the user chose cmb1 - C then chose cmb2 - 1, cmb3 would then show the options Random1, Random2, Random3 etc..
At the moment I have a table with 3 columns. Within the table is every possible combination of the drop down, i.e:
-A l 1 l Option1 l
-A l 1 l Option2 l
-C l 1 l Random1 l
-C l 1 l Random2 l
Etc...
I have tried to use the example shown on this website but i've had no luck: fontstuff.com/access/acctut10 (If you look at "Example 2", thats what I tried to do)
