Subform In A Form Doesn Show Controls When Link Child And Master Fields Derfined
Jun 13, 2005Hello,
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
Forms :: Subforms Master / Child Link
Apr 9, 2015I 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.

Oct 7, 2012I 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:
'----------------------------

' 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.

Forms :: Selecting Record In Parent Subform From Child Continuous Subform
Jan 26, 2014I have two subforms on a main form. Both use similar queries and nearly the same set of records and PK. The first subform is for data entry and the 2nd subform is a continuous form that lists the entries in order that are made from the 1st Subform. (for entering in vacation days and appointments)
The continuous form cannot be edited, it is to be a list for viewing the information only.
I have an edit button next to each record on the continuous form. When the button is clicked, I want it to take the 1st subform to that specific record as well (same PK), so the information can be edited there.
I cannot figure out how to get the 1st subform to go to the record on the continuous form when the button next to that record is clicked on the continuous form.
I tried the DoCmdSearch for record and just keep getting object is not open errors.
Modules & VBA :: Can Filter Child Subform From Parent Form?

View 1 Replies View RelatedForms :: Navigation Combobox Ignoring Subform Master-child Relationship?
Jun 17, 2015I 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.
Forms :: Subform Control Event - Identify Parent And Child Forms
Jun 20, 2013I 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.
Child/Master Problem
Feb 10, 2005HI 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?

Opinions On Master/Child Relationships
May 3, 2005Hi,
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?

Parent-Child Cascading Deletes
Nov 4, 2007I have a simple Family table:
PersonID
Name
ParentID
where, in the case of a child, its ParentID contains the PersonID of its parent.
In the Relataionships window I put two such tables, Family and Family_1 and I joined Family.ParentID to Family_1.PersonID. I set referential integrity, cascading updates and cascade deletes.
I made a Parents form (by setting the ParentID criteria to Is Null), and added a Children subform (linking the ParentID of the subform to the PersonID of the main form).
The cascading updates works when I add a new child but when I try to delete a parent I get the error: Could not update; currently locked.
Why doesn't the cascade delete work?
Update Subforms - No Parent/Child
Dec 24, 2005I 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.
Child Form Loads Before Parent?
Jan 26, 2006Hi,
I've got a parent/sub-form set up, both of which derive their data from linked tables connecting to a central database. As a result I've had to add coding to the NewRecord events to fetch the next primary keys from the database.
Unfortunately I'm finding that one loading the new record, the child form seems to be loading before the parent, ie the child form_Current event occurs before the parent form_Current event. Is this how it should be? It seems intuitive that the parent should load first.
I'm sure I can develop some cunning logic to get around this problem but I'm sure there must be a better way. Has anyone any experience of this parent/child set-up with linked, central database tables?
thanks!
Dave
Limiting Number Of Child Fields Per Parent
Sep 23, 2005I have a field in the parent table which indicates how many child tables there should be at the most. I'm uncertain about how to enforce this. I"m using access as the database to a Vb.net app. Should I do it in access or Vb.net or both.

Oct 16, 2007Hi
I have a parent-child base table (accounts) with the following fields:
- id
- parentid
- name
every record's parentid is either 0 ( which means it is in the most upper level) or another record's id (which means it is the other record's child)
different levels of records are being used. I mean some accounts are used in the most 1st level with no childs, some in the second level, ....
I need a query to list the accounts which are not parent to any othe records, regardless of what level they are defined.
Thanks again for the help.
Duplicating Parent And Related Child Records
Dec 18, 2006I am creating a purchase request form for my company. The main form contains the PO Request # (autonumber) and general vendor and shipping information. The subform contains the item numbers on the order, the quantity and costs. What I am trying to do is make it so that users can click a "duplicate" button on the main form of an existing PO Request and have all the data replicated into a new PO Request. A lot of what we order is repetitious and it would time saving if users could just duplicate an order and modify as necessary. Can anyone help me with this one...
Thanks!:confused:

How To Add New Record From A Form To All Parent And Child Tables
Jul 27, 2015I have one parent table with 6 child tables (all child tables are linked to the parent table in the relationship through the BoardID autonumber field, and they are all one-to-one relationships). All of the tables feed into one form. I have added the "add new record" button to the form, but when I click on it, it only adds a record to the parent table. The only way I have found to solve this is to go into each individual table and add a new record. Is it possible to have a new record added to every table when I click the "add new record" button on the form?
View 7 Replies View RelatedForms :: Creating Parent / Child Relationship Within Form
Apr 3, 2013I 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.
Forms :: M2M / Master Child Form Design - Trigger Event?
Oct 14, 2013How 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?
Trouble Updating Parent Tables With Child Table/form
Jul 6, 2006Sorry this is so long but I am trying to make it as detailed as possible...
The Setup
My database is similar to the sample "Service Call" db. I have a main table called "tblTT" which has an autonumber primary key. The table also contains several foreign keys such as UserID (not an autonumber) from "tblUser", TechID (also not an autonumber) from "tblTech", etc. I have the relationships setup with "Enforced Referential Integrity" for both updating and deleting records. Each relationship has a RIGHT OUTER JOIN ("Join 3" in access) so that all records from child (tblTT) and only equal from parent (tblUser, tblTech, etc.) will be included. I have a form for nearly every table which serves different purposes but the main function of the DB is to create new Trouble Tickets (TT's), a.k.a. service calls. Therefore the main form used is my "frmTT" form in add mode. The form contains all the fields from my "tblTT" table and contains (directly) no fields from any other table (I guess indirectly it contains fields from all the parent tables...).
The Problem
When I pull up "frmTT" and try to create a new Trouble Ticket for a user that does not yet exist in the table "tblUser" I get the error "You cannot add or change a record bcause a related record is required in table 'tblUser'".
What I want is for my users (the "Techs") to be able to create a new Trouble Ticket without having to worry about populating the "tblUser" table (and other parent tables) first.
My Solution
I was going to (and unless someone can find an answer for me still will) fix this using VB script by setting up a query to check all the parent tables for the values in their corresponding fields in the form. If the query returns no results an "INSERT INTO" statement will run to populate the parents tables so that the form will save itself into the Trouble Ticket table ("tblTT").
I feel that this is a huge work around and not the proper fix. I would prefer to do this the right way both to have a correctly setup DB and for future reference. Can anyone help me with this?
Thanks,
Andy
Queries :: Parent Child Query - Sum Images In Main Record
Oct 15, 2014I'm trying to create a capacity report for my database. Originally, I only had the one table, which summed the number of Packs and number of Images, worked out percentage capacity used and then put it in a report, showing for each week of the year. However since then, I've added a child table to this, allowing me to create subrecords. The reason we did this was so we could easily group together multiple mailings under one single master record, so to speak.
Going back to the capacity, I've managed to work it so the Pack capacity is worked out from the mailing quantity in the subrecord. However, the number of Images is only entered onto the Parent record. Now my capacity query is summing the same number of images as there are subrecords, where in reality I only want it to sum the Images in the main record. I know I could add an Images field to the child table and work it out the same way, but I'd rather not do that (because that's not how our business works).
So essentially the question is, how can I sum the Images from the parent table without repeating the sum and massively overexagerating the sum?

Tables :: Developing Related Multi Level Child Parent Tables?
Jan 14, 2013I have created a table that acts as a header for my data and a second table that acts as line item data. What I need to do now is add a second child table that uses the line item data as its parent table and stores associated line items for each record. Is this possible?
This is a skeleton view of what I'm going for:
Master Table:
tlbAuditReportHeader
- AuditDate
- AuditArea
- Auditor
Sub Table:
tblDiscrepancy
- Discrepancy
- CorrectiveAction
- ActualCompletionDate
- VerifiedDate
- Notes
Sub table to Sub Table
tblFollowUp
- FollowUpDate
- AssignedTo
- SpokeWith
- EstimatedCompletionDate
- Notes
Sometimes tasks change hands or are pushed back depending on work load. It would be nice to be able to track something like this.
