Prevent Subform From Updating If Main Form Data Is Invalid
Nov 4, 2005
Hi,
Mainform and Subform are linked on field "barcode".
Barcode is the primary key for the table that Mainform is based on.
When user is entering a new record, I have the BeforeUpdate event of Mainform.barcode set to check to see if the barcode already exists in the table, and if so, to give the user some meaningful error message.
Works fine, except that the subform still updates to match the invalid, previously-used barcode. I want the subform to stay blank until the user has entered valid data in MainForm.
How do I accomplish this?
Thanks for any ideas.

Hi, I have a problem I don't know how to solve it. I have a subform in datasheet view, linked to the main form. There is a running total on the main form based on a dsum on a field of the subform.
When I delete a row on the subform datasheet, the main form calculation is not automatically updated. I had to create a "update" button to do the refresh.
Is there a "on record delete" event available for a datasheet sub form?
Thank you for any help.

I have a navigation tab with 6 sections, of the 6, 5 of them are self-made split view with a form view on top and datasheet on bottom and upon adding records through a command button on form view I would like the datasheets to update.
On other forms it would (I believe) update to the bottom of the datasheet, now on the ones I've been banging my head against it either replaces the top record or doesn't show up unless I switch tabs and switch back. From my searches I assume this is in need of a requery...

Within my main form I have a combo box called "workgroup." Also in the main form is a subform called "sfrmSubmissionRecords," and within this subform is a combo box called "covermemo."
Each cover memo is assigned to a specific workgroup, so my intention is for each time a new workgroup is selected from the dropdown, the covermemo combo box in the subform becomes populated only with the covermemos associated with that workgroup. I'm almost finished except for the final step when I try to make the values regenerate...Access says that can't find the referenced form "sfrmSubmissionRecords"
This is the code that I'm using:
Private Sub cmbWorkgroup_AfterUpdate()
Forms![sfrmSubmissionRecords]![cmbCovermemo].Requery
End Sub

I'm supporting some Access/VBA code which includes the following behavior:
When an update is made in a (linked) child form, the current date/time is written to a textbox on the main form via
Me.Parent!txtMod = Now
Likewise, the BeforeUpdate event of the main form updates the same field (and then does a bunch of form validity checks, possibly followed by a Save).
When we upgraded to Access 2003 from Access 2000, a problem erupted:
When the user returns to the main form (by clicking on any control outside the subform), the following message is issued: "This record has been changed by another user since you started editing it (etc.)..."
At this point the user must choose between "Save Record", "Copy to Clipboard" and "Drop Changes".
Conceptually, I see why this is happening (though I wonder why Access 2000 didn't flag it). The subform is the "other user". When the main form is returned to, it is "Dirty" (unsaved update), so the main form's BeforeUpdate event fires, and attempts to update the field again (Me.txtMod = Now). Since there is a pending change to the field, an error dialog pops up.
As a quick fix, I replaced the code in the subform with a flag ("Hey, I've been updated!"), which the main form checks on the Exit event of the subform control. But that seems a horrible solution. Surely there's a better way?
Notes:
1. It would be preferable to have the timestamp updated right away by the subform, though having it updated when the subform loses focus is better than nothing.
2. Since a subform is a control from the main form's perspective, I'm surprised that a change to that control doesn't render the main form "Dirty". I guess from a database standpoint it makes sense (the form's table isn't getting updated at all; just the subform's). But then, how does the main form know that the subform has been updated?
3. I tried catching the error via Form_Error. I can make the dialog not appear via "Response = acDataErrContinue", but unfortunately it defaults to dropping the changes (old and new), rather than saving the new.

I have a main form and a subform.
Both forms have the field called JobID in common.
Both forms have a field called JobStatus.
Any easiest solution so that After I Update the field called JobStatus in the subform, it changes the field called JobStatus in the main form to the value which was selected from the subform?.

Hey Everyone,
I am stuck trying to figure out this problem. I have a main form "frm_tirelog_600" which has 4 combo boxes "cboleg",
"cbocar", "cbopos", "cboserial" on it. The first 3 combo boxes are used as criteria on 1 of 3 subforms that I have.
The fourth combo box "cboserial" is used for the criteria in a query on another subform that I have called "frm_mount_600_subform",
which is independant from the main form, I hope I have explained that clearly enough. What I need to be able to do is
have the subform fill in 3 of the fields on it "leg", "car", "pos" with the value from the 3 combo boxes on my main form. I
can get it to show in the fields but not write to the table. I have searched the forum and have not been able to locate anything
that would work and really need any assistance with this. Im not real strong in the coding department which is where I
beleive this could be done.
I have attached a copy of my DB which I hope will better explain it. Any help would be greatly appreciated

I have an unbound subform within a main form that i add data to.
Once I click save to save all the data the subform data will save itself into tblPerson and the main form data will save itself in tblSupplier.
The tblPerson will have an autonumber for the whole record, i need this autonumber to save in tblSupplier, only this autonumber.

I have tblEmployees for employee info
tblEmployeeAbsences for employee absences
tblVacation for employee vacation info
While entering the employees hours I want an adjacent subform to show the matching employees absence and vacation days taken if any.My approach was to use a Cartesian qry for the record source for the subform and link it with a fake key from the main form.

I have a main form that has some sub forms on it linked by master child on PK. When I select a new record on the sub forms I want to take a date value from the main form and populate the value into a field in the sub form. How do I do this as I cannot see a new record event on the sub form?
help would be much appreciated.

Hello, I'm trying to use information based on items selected in a combobox in the main form. Once the user selects the desired info in the comboboxes on the main form, I want the subform to display the data that matches the search criteria in the main form. For instance, if I select a job number, I want everything that matches that job number to be displayed the subform (along with the corresponding job name, version, etc.). I also want to get more specific in a search where I could select a job number, job name, and job version from the comboboxes in the main form to where all the data that matches the search criteria in the main form will be displayed in the subform.
Attached is what I have so far. The form I'm trying to perform this in is the SearchByResults form and the subform is the qryk95 form. I'm trying to populate this using the K95-Template table. I performed a query (qryk95) to select only the fields I want to display in my subform. Any help would be much appreciated.

I'm trying to create a report that contains data from a "main" form and a subform. However, I can't get the main form data to populate no matter what I try. I've been through all sorts of queries and just can't get it to work. The main form and subform are both separate tables, and there are no redundant fields.
Basically, the main form is an inventory of assets, and the subform is designed as a way to submit trouble tickets when one of those assets requires maintenance or repair.

I have a main form titled "projects" with a subform titled "inventory". They are linked by two fields "project" and "fiscal year" with a one to many relationship. These fields are also the primary keys in the main form. I also have the referential integrity option activated.
Whenever data is entered in the subform inventory, it duplicates the main form and all the other subforms linked to the main form. (I have about 11 other subforms linked to the main form). So if I enter 2 records in the inventory tab, there will be 2 records for the same project and fiscal year in the subform and all the other linked subforms with the same data, so it is almost like it is seeing the inventory subform as the main form. I have tried deleting the duplicate record from the main form, then it deletes the 2nd entry of the subform. I have attached a pdf with a print screen of the 2 duplicate records with the same fiscal year and project name.
I have another form called Notes that has a similar relationship, but doesn't have this problem. I think it might have something to do with the conversion. I originally created the database with Access 97 and we are now using Access 2007. Am I missing something that needs to be done in Access 2007 to link the 2 forms, so I can enter records in the subform without duplications?
Also, the database is split so there is a back end and front end. I have all the tables and relationships set in the back end.

I have a main form with several linked by ID worksheet sub-forms. I would like to add a on-click function to delete the main form and all related record on each sub-form. I have tried several methods but nothing is working correctly. The cascading delete function is not available as part of the form relationships. How I can accomplish this?

I have a mainform set to data entry to add records to TABLE1. I inserted a subform that shows fields from TABLE2. I have a field in TABLE2, let's say TBL2FLD1(NUMBER). I want to add TBL1FLD2(NUMBER) from TABLE1 in the mainform to TBL2FLD1 and update said field in TABLE2.
My problem is:
(1) I get a #TYPE! error when I try to add the two fields, which I have tried many, many ways (adding them together in the Default Value; creating an unbound field to hold the calculation and then putting that field into the Default Value of TBL2FLD1; ETC), and
(2) I don't know how to get the subform to update TABLE2. It seems like the control gets stuck in the subform. Is there a way to accomplish this without coding it?

So I am creating a Complaint Tracking Database with Access 2013. In my 'complaint entry form' I have added to ability to "Open" and "Close" the complaint. While the complaint is open the user is able to enter/edit data in the complaint (new or old). When the complaint is "Closed" (done so with a button on the form that prompts the user to enter a date of their choice) the user should not be able to enter/edit data in the given complaint. In my original thinking, I placed checks on various events (on load, after update, on click) that checked to see if the current complaint had a date in the "Close date" field.
If the close date field was null then that meant that the complaint was open and the the controls would NOT be locked. If the close date field was NOT null (i.e. a date was present) then the complaint was closed and the main form fields were locked but the data was still viewable and unless they "re-opened" the complaint they could not change the data.
Now, in the complaint entry form, I have a subform that acts as a action tracker that is used by the user to keep track of the actions taken on the complaint (i.e. they requested documentation from such and such on this date..etc). My problem through all of this is upon closing the complaint and locking the main form controls, my subforms data just vanishes! At first I figured the problem might be with the linking of master and child fields, so I made sure that I left the ID in the main form unlocked when I loop through my controls during the locking process. This did not solve my problem. Code below:
Private Sub Form_Load()
Dim ctl As Control
If Not IsNull(Me.close_date) Then
Me.FormHeader.Visible = True
Me.btnClosed.Enabled = False
Me.btnOpen.Enabled = True
For Each ctl In Me.Controls
[Code] .....

I have a form that request the User to enter a Parcel ID number (99-9a-99-99aaa-aaa-aaaa). The sub form asks for the subdivision number, block number, and lot number. The subdivision number, block number and lot number are normally part of the Parcel ID number but sometimes they can be different. I want the sub form to fill in the Subdivision number, block number, and lot number as a default but allow the user to change the value if needed. currently the sub form will only show what is entered into the table itself if a change is made on the main form the sub form does not reflect the change.

I have a pretty simple form that includes subform. Subform's table is linked to main form's table with parent/child relation. Connecting fields are main table's ID field and corresponding field in child table. Subform is in datasheet view. This is pretty basic stuff so there should not be any problems, but every time I apply a quick filter in main form it causes data in subform become invisible. There is single row in subform, but all it's fields are empty.

I have a form with subform (datasheet) .
On my subform i have one field which shows the
productId ( which is filtered from combo boxes on main form) .
productId contains two columns
1 bound column(id) ( hidden with width 0 )
2 column (desription) ( shown with width 2 )
Now after entering the data when i come back to the form again . It hides the data from the productId field on subform , because data in combo box (on main form) doesn't match. Although the row is showing up , only the text in field (productId) is hidden.
Now when i change data in combo box on main form to match the ProductId , then the productId field text shows again. after changing combo box it hides . What i need is the existing data should not hide when i change the combo box selection.
see pic 1 where product matches and pic 2 where not. please note i am using master child relationship on the form/subform.

Hello all,
I have 5 check boxes on a form and one of them must be checked in order to get the correct result.
If the user does not check any of the the five checkboxes he gets a msgbox telling him that he must checks one of the checkboxes.
What i want to ask is if is possible to prevent the form from updating? Because the user gets the error message but after that the form is being updated even though he hasn't check any of the fields.
Thank you in advance!

I have a subform which makes a change to a field on the main form. When focus is returned to the main form, the BeforeUpdate and AfterUpdate events fire. Why? I thought from the form's perspective, the subform is just another control.
BTW, I get the same behavior if I modify the field from within the Exit event of the subform control.
In either case, the main form's Dirty event is NOT triggered.

I am working on a web database with a form which is bound to an underlying web table where the submissions occur.My challenge is that the fields on the form get submitted to the table even before the submit button is clicked regardless of whether the form was completely filled.
My request is that I want the form to only submit to the submission table only when the submit button is clicked.When I searched on the net, the only solutions I got are VBA written code but my web database cannot use VBA code.
VBA code:
Option Compare Database
Option Explicit
Private blnGood As Boolean
Private Sub cmdSave_Click()
blnGood = True
Call DoCmd.RunCommand(acCmdSaveRecord)
blnGood = False
End Sub
[code]....

Here's the issue: I have a main form with a subform on it. The main form's record source is called "tblMainForm" with one field in it-MainFormPK-the primary key. The subform's record source is another table called "tblSubform" and it has three fields-SubformPK (the primary key), MainFormPK (foreign key) and DataEntry-a standard text field.
I want to create a new record so I open the main form and am immediately brought to the subform's text box whose control source is DataEntry. I enter something into the text box and close the form. What I entered into the text box is saved in tblSubform but the main form did not create a new record therefore MainFormPK was not automatically entered as the foreign key in tblSubform and there is no link between the forms. (By the way, the Master and Child fields are set properly.)
My question: Is it mandatory that the main form containing a subform have a data entry field? If not, does anyone know of a way around it? Thanks for any help.
