Forms :: Subforms Master / Child Link
Apr 9, 2015
I am building a user creation form. I have built it with 3 subforms
Subform 1 is voor general information about the user.
Subform 2 is some more specific information about the user
Subform 3 is more info about the same user.
Now when I create a user (record) in subform 1 it gets the primary key lets say 14. Then when i add information in subform 2. I want it to grab the Primary key 14 from subform 1. So that the information which is inputted in subform 2 will be related to information from subform 1. I get it working if I make a Main form and then put subform 2 and 3 in a subform and then let them grab the primary key from the main form. But how does this work with 3 subforms and no mainform.

Hello,
I have a form and a subform in MS Access 2003. I have made some changes to database structure, so I decided to change the subform also. When I changed the Link child and link master fields, the controls of the subdatasheet dissapear- they show only in design view. If I clear the contents of Link child and link master fields they appear again, but the records are not binded.
Is there a setting on the parent form that also has to be changed, to make the new binding?
Thanks,
Aleksander

How to structure some MS Access 2007 Forms for the following scenario.
My table structure is as follows:
Product
++++++
ID (pk)
ProductName
...
Tag
++++
ID (pk)
TagName
ProductTag
+++++++++
ProductID (fk)
TagID (fk)
I want to have a main form that allows me to search for and displays a list of all products (and the dozen or so attributes for each product) that meet that criteria (I'm thinking a continuous form view of products).
So far so good. No problems.
Now I want a "tagging" form to the right of my continuous forms product list that is linked to the product which currently has focus. The tag panel should always show a complete list of all Tags. I want a checkbox next to each tag that I can switch on and off whether that tag applies to the currently selected Product. I also want to be able to add tags on the fly (without leaving the main form).
I think I have three forms in play :
Main Form
Product Form (subform to Main) my product search criteria is probably on this form header.
Tag Form (also subform to Main)
But with this approach I'm have trouble linking the two sub forms to each other. Actually, I'm having huge trouble figuring out how to display the list of all tags with a check box that when checked on and off creates / deletes a record in the ProductTag table and I really want Access to do as much of the CRUD as possible. I would prefer to avoid writing screeds of SQL INSERTS/DELETES on events. Am I asking too much of Access?

I have a form which I am using child/master fields to create a filter (see attached pic)
For the date ranges I need these to be
>= Start Date and <= Actual Finish Date
How can I set the criteria for these two fields, so that when someone picks a date it knows it's from or before the date entered.

I have a form, frmProjects, with a continuous subform, sfrPeopleOnThisProject. They have a master-child relationship. The form shows one Project record at a time, while the subform shows all the People records for that project. This works as expected - the correct records show up in the subform as you move through the form records.
To make it easier to glance through the list of subform records (as they can sometimes be quite long), I've added a navigation combobox to the header of the subform. If I understand correctly, as the combobox is within the subform, it should obey the master-child relationship: it should only show the subform records associated with the main form's current record. It does not. Instead, the combo box collects *all* of the records from the table that the subform is based on. So, choose the record for Project 1 in the main form. Up pops the 2 people on Project 1, but the combo box lists both the 2 people on Project 1 and the 3 people on Project 2.
The row source for the subform combo box is:
SELECT tblPersonOnProject.PersonOnProjectID, tblPerson.Fullname FROM tblPersonOnProject INNER JOIN tblPerson ON tblPersonOnProject.PersonFK=tblPerson.PersonID ORDER BY Fullname;
I can make the combo box perform as required by adding "WHERE Project=Forms!frmProject!ProjectID" to the row source and placing a hidden textbox on the main form for ProjectID (the autogenerated primary key) to sit. Have I misunderstood the point of the master-child relationship in the subform? This hidden textbox thing can't be correct.

HI everyone, I have a Sales Invoice form with a Receipts subform showing what receipts have been lodged against that invoice. It works fine as long as there is one receipt or more.
The problem is when no receipts have been lodged and there are no receipts to show in the subform. When I open the Sales invoice form I get a "you entered an expression with no value" error, then the Sales invoice form opens. I tried suppressing the warning with DoCmd.SetWarning False, but that hasn't worked.
Anyone know a workaround?

Hi,
We all know we're not supposed to duplicate data right? So was wondering how people deal with the deletion of Master records.
For instance let's say I have 3 tables.
tblSales
tblSalesSub
tblProducts
tblSales - lists the sales summary - stuff like SaleId, SaleDate, SaleTotal
tblSalesSub - lists the products contained within the sale.
tblProducts - is the Master list of products storing the product specifics
Now to prevent duplication of data I should just store the productId in tblSalesSub then reference that to tblProducts with an innner JOIN of some kind.
But what if the Master record gets deleted? The reference is broken and NULL values are returned.
How do you deal with this?
Don't allow deletion of these records?But just hide them when deleted?
Duplicate data by storing the product title and description within tblSalesSub?
Tell the user - tough cheese you shouldn't have deleted it should you?
Any other ideas?
Dan

Let's say :
1 navigation form called Nav_Main
2 subforms :
1 called master_form ( PK = id_master) (table : master_table)
1 called details_form (with id_master in it) (tables : details_table)
the relationship is still established
I want to switch from master_form to details_form and retrieve only records corresponding to the last id_master where I was in master_form
(do I absolutely need to recreate a parameter query of details_table ?) What is (are) the simple way(s) to do it ?

I have a main form with 2 subforms. Subform 1 shows the results of query 1, subform 2 shows the results of query 2.
Query 2 uses query 1 as a starting point. Query 1 is updated with an option group on the main form. In other words, when I select an option on the main form, qdef for query 1 is updated and query 2 will also be affected.
If I select an option the subforms don’t update. If I close and reopen the main form, the subforms show the correct information so the queries are being updated but the subforms are not showing the updated information.
I’ve been trying to requery the subforms using the following code in the OptionGroup_Click() event:
Forms![MainForm].[Subform1].Requery
Forms![MainForm].[Subform1].Requery
By the way, I don’t have any parent/child relationships.
Am I missing something simple.

I need help! I've set up a database with a subform that worked until recently. I get an error message that says: The LinkMasterFields property setting has produced this error:'Invalid outside procedure'
I had added a date and time stamp for when something gets modified it changes the date/time. I even backtracked and took all that out from tables, forms, queries etc. but the error keeps appearing when I'm trying to update my subform.
Thanks,
supan

I have a master table with about 40 fields. In addition, I created eight child tables with read only datasheet views of limited fields from the master table. The child table views are based on certain critera in the master table and are being refreshed by using delete and append queries tied to the On Current property of a form. By double-clicking a specific child record, a form is opened to allow editing of the master record. Also, I am using Referential Integrity and Cascade Update Related Fields to update the child table when a change is made to the master. However, I do not know how to add a record to one or more child tables when a record is added to the master table. The new child record would have to be based on the same critera that the append queries use so it gets added to the correct child table or tables.

I was wondering if it was possible to have a master table where say 10 of my regulatory tables and their data once inputted from the forms will appear there? Is this possible? Because right now, each of my regulatory tables has a form where the data is inputted and appears within said table.
All these tables are separate, obviously. I want to consolidate all the information into one spot, is this a possibility within access?

I downloaded a sample treeview application I have modified most of its to suit my need, except one thing. I want link parent/child node the main form to the main form through a subform on the CategoryID.
The following is the original code where when a child not is clicked only pops up a "linked" msgbox. I need to modify the part of the code on the Select Case "C" in red:
Code:
'----------------------------
Sub DisplayForm(i As Integer)
'----------------------------
' for this Treeview I do not want a double-click on a parent node
' to open the applicable Category form, but pressing the shift key
' should open the marriage form applicable to the parent node. Shift
' or double-click on a child node should open the applicable
' offence form.
Dim strKey As String
Dim strTag As String
Dim strFilter As String
[Code] ....

I am trying to create a database for a cub scout pack that just keeps scouts information, medical info, parents info, and parents medical info each is a seperate table. I have created a Tab controlled form with 4 tabs. On each tab the ONLY thing I have is a subform that contains the appropriate information. Each table has it's own form with the table as it's record source. I link the scouts table to the medical table by SID which is a primary key in the Scouts table. I link the Scouts table to the Parents table with a PID which is the Primary Key in my Parents table, and I link the Parents with the ParentsMed with a PMedID, key in the ParentsMed table.
Question #1 - Using a Tab Control you can only have 1 record source. What should I use? I have tried the tblScouts and I have also created a query with every field from every table.
#2 - When I try to use the parent and child links on the subform I get the error "Can't build a link between unbound forms" but each form is bound to the table and the record source on the tab control has had a table and my qryEverything, neither work. I can type in SID but it still doesn't function properly.
Any suggestions or comments on a better relationship method or any insight on how tab controls are supposed to be setup or anything would be greatly appreciated.
Thanks a lot
Rick

Hi there. I need a way to pass data between forms, and subforms. I have "form1" which simply contains a text box requiring the user to input an ID which I will call "PID". it also has a button which has the following code:
Private Sub Command5_Click()
On Error GoTo Err_Command5_Click
Dim stDocName As String
Dim stLinkCriteria As String
stLinkCriteria = "[PID]=" & Me.PID
stDocName = "TestExam"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Exit_Command5_Click:
Exit Sub
Err_Command5_Click:
MsgBox Err.Description
Resume Exit_Command5_Click
End Sub
On the form testExam, I have a page control with 3 separate tabs. For each tab, I've embedded three separate subforms. All forms involved, including the container form (testExam) are bound to separate tables. All tables have one common field - PID
I'd like the user to only have to input the PID on one form, and have it trickle down to all subforms.
In the FOrm_Current sub of the testExam form, I have the following code:
Private Sub Form_Current()
[PID] = Forms!frmForm1.PID
End Sub
Using this code, I am able to pass the data from Form1 to testExam, have the PID on testExam filled in and on tab 2. But tab 1 will not populate automatically. I have no idea why. I don't know where to start troubleshooting this.
Please help.
Is this even a good way to pass data between subforms?

I have a listbox on a subform (or a subform within a subform).
When it is clicked I want all other listboxes to unselect.
There may be listboxes on the mainform, on other subforms, on other subforms of subforms.
I imagine I'm looking at a recursive function of some sort, but I'm not entirely sure of syntax to identify parent and children forms...
pseudocode so far:
loop all controls
if control = listbox, unselect all
if control = subform - recurse: loop all subform controls
if control = parent... err... Fail.

I have done this by linking the relationship between a person and a company (company-personID) with the table "alternates". In a subform for the information about the company itself, it shows the people associated with the company, as well as their alternates (assuming they're a director). It works just fine when I view a director's alternate, as John Tong here has his alternate as the person with relationship number 7. However, the whole thing is made useless when I view it from an alternate director's point of view, like Peter Chan, where he's displayed as the director, and the alternate is null. After poking around for a bit, it turns out that the child field is ALWAYS director.
What I want is for it to show the alternate or director based on who's being shown in the subform, i.e. Peter Chan is filled as alternate with the director being shown as "1". I've tried setting up expressions and putting up multiple master and child fields, but they just mess up Access.how I could display the names instead of the company-personID in the "alternates" subform,.

I have a relationship between two tables; the parent table is "Client Information" with a primary key of "Client_ID", the child table is "Event Information" and the foreign key is "Client_ID".
I know that within the Event Information table I can select which Client_ID to use as the link. I want to have that done within a form, however. I have a form for Client Information with a subform for Event Information. If I go into the table and manually set the Client_ID then everything displays fine.
How can I set the Client_ID in the subform to automatically match the Client_ID in the main form? I can only assume that these solutions require the parent/child relationship to already have been established.

I have an unbound new contact data entry form that adds records to many different tables. I have no problems adding one record to a child table at a time, but one of the things we are collecting is a list of online networks a person belongs to, and I want to be able to stick a "check all that apply box" on my form and have it add multiple records to the child table. Here's the basic set up, I have a parent table with the main contact information with a primary key field "IID", a lookup table with "Facebook, LinkedIn, Twitter..." etc in it with a primary key field "online_id", and a bridge table to link the two which should have multiple entries for IID, one for each online_id. I want to use a listbox (or something like it) that the user can select multiple online networks and then have records added to the bridge table. I can figure out how to add the listbox on the form, what I can't figure out is how to get the values out of the listbox. T

I have a form, a subform and a master unique table. I need the unique table to updated in the following manner: Form has certain fields that need to be assigned to every record created in the subform[id] and [info1] Subform has a unique [caseid], and contains further [info2] but needs to be bound into [id] in the main form. Example of the master unique table:
id info1 caseid info2
1 aaa 1001 asd
1 aaa 1002 dfg
2 bbb 1003 fff
3 ccc 1004 ffg
3 ccc 1005 ggh
I've managed to accomplish this with a linked table&subform structure, but the master unique table looks like crap because it collapses the subform values into sub-records in the master table when the [id] is similar. The data is in the rigth place, i just want it not to be collapsed/expanded, but every unique recors shows in the table in the regular format

I have several Suppliers, each of whom holds several SalesEvents. At each SalesEvent I might buy none, one or more Bundles. Each Bundle then contains one or more Items. These relationships are all reflected in my Access 2013 desktop db as one-many relationships with cascaded updates.
My form structure for data entry reflects the Relationships, in that I have a Supplier form with a SalesEvents subform. On that subform I can enter data about each of that Supplier's SalesEvents, and each SalesEvent row has a button to call up a SalesEvent form which has a Bundles subform. Then each row of that subform has a button which calls up a Bundle form containing an Items subform. That Bundle form identifies the Supplier, Sales Event and Bundle number, and within its Items subform I can then enter the data for each Item.
Problem : All used to work fine, but I've clearly changed something because now when I select the Items button on the Items subform in the Bundle form, the system gives me the data for the first record in the SalesEvents table, rather than the one selected. I have checked the raw data and that's as it should be. I have tried to undo all the steps I took since it last worked properly, but to no avail. Restoring the last backup (taken when I'm sure it worked properly) still has the problem.how do I find what data is actually being passed between forms and subforms ?
