Forms :: How To Update Main Form From Calculated Field In Subform
Aug 21, 2013
I have a subform embedded in a main form, the subform has a field (text box) that is doing automatic calculation so no manual entries are needed from the user. I have tried to pass automatically the final result to a text box in the main form, but all events are not working (afterupdate, On change, On Dirty), etc.
I have a button to do the above mentioned in the main form, but I don’t want to use that button, I want to do all the process from the subform.
Also, from the subform I was able to do click on the button on the main form (programmatically), however MS Access is too quick and the value extracted from the subform is always empty (zero); Acees is finishing before the calculation is done.
I am using MS Access 2010.

I have a main form with several with four subforms. On the main form I have a bound text box [ShiftTotal] I have on each subform a unbound text box that sums a field [ExtTaxIn]. I am working with just one subform till I can get it to work correctly. The code I am using on the after update event is as follows.
code
Private Sub TxtSoldQty_AfterUpdate()
On Error GoTo HandleError
Me.ExtTaxIn = (Me.TxtSoldQty * Me.TaxIn)
Me.ExtPrice = (Me.TxtSoldQty * Me.Price)
Me.InvSold = (Me.TxtSoldQty * Me.UnitOfSale)
Forms!frmShiftMain!TxtShiftTotal = Forms!frmShiftMain!TxtRunningTotal
Me.txtExtTaxIn.Requery
[code]...
This sort of works but the [ShiftTotal] on the main form is always one table row behind. I think this is because of the order the event fires.

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?.

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?

This is an employee timekeeping database. I have a main form "frmTEMain", with a tab subform named "frmGridsub" with a tab named "Grid" on the lower half. On the tab page is the "frmGridsub" a continuous form that looks like a datasheet, many horizontal rows of data. The subform works correctly with several combo boxes that auto populate. There are many different employees listed in the Grid subform. "Employee" is the name used for the field that holds the unique ID number in the tables that feed the subform. The subform populates another table "dbo_BCRC."
When I click on a row in the subform I want fields to update on the Main Form with Employee, LastName, FirstName, that come from the table that was populated when data was entered into the subform. As the person clicks on the various rows in the subform, the main form fields need to synch with the row.
Do I use "Got Focus" event? Do I need to create another subform and place it on the top half of the Main Form?
I can provide screen shots....

I have a form called CostingForm. This form has a subform called CostingSubform. The subform's data source is a table called Costing Table. The main form has a combobox that has all the "Field names" or headers from the Costing Table that populates with the on open event. I also have a non bound textbox on the main form. What I would like to be able to do is input a value in the textbox, select a field name from the combobox and with an "update" button update the corresponding fields on the subform with the value in the textbox. Is this even possible?

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.

How can I get the value from a field in one table (in the sub form) to copy/insert into a field in another table (in the main form) when adding a new record?The main form and sub form are linked using parent/child linking, and the sub form is in a tab.I have table A (Visit Dates) in the main form which is used to record the date of a visit to a church. Table B (Quarters and Peals) is used to record an event that took place at that church during that visit. Note that not all visits in table A require a record to be created in table B - but half or more do.
In tables A and B I have a field called "QuarterOrPealID" and these are both primary keys, though the field in table B is set to 'no duplicates' and in table A it's set to 'duplicates allowed', as table A has its own auto number/pk. They are both linked in the relationships.
So, when I add a new record to table A using the main form, I might then need to click on the tab in the sub form to create a new record in table B, which has to be linked to the same record in table A. When the "QuarterOrPealID" auto number/pk is generated in the sub form (table B), I need that value to update to the "QuarterOrPealID" field of the main form (table A), so that when I'm viewing these records the form pulls all the information nicely together.

I have a music database. It's somewhat over the top in terms of the information stored in it, but I like it. My issue is with getting the total number of tracks, as well as the total duration, for a given album (and for each disc, but if I can solve one that should also solve the other).
I have a lot of tables and forms, but for this problem I only need to deal with two of each. They are the tables for albums, the table for tracks, and their associated forms.
In my album table I have information such as album title, artist, release date, and album length. The tracks table contains information on each song - track title, track number, parent album, and track length.
My main form is for the album itself, and contains a subform for the tracks on said album. They correspond to the relevant tables.
What I want to do is obtain the value of the album length by calculating the sum of the track lengths for that album, and the number of tracks. Easy enough - Sum(TrackLength) and Count(TrackID) respectively, both of which can be stored in the footer of the subform.
My problem is that, rather than simply copying those values into text boxes on the main form, I want to copy them into actual fields in the album table. Furthermore, I want them to update as I add or edit the track lengths in the subform.

I have an entry form with a field(combo box) called cboGetCode. I also have a sub form (continuous form) with number of fields, also an entry form. Now, I have added a code behind the cboGetCode AfterUpdate event to populate the result to relevant fields in the main form.
PHP Code:
Me.lngSCode = DLookup("[lngSchoolCode]", "[qrReadingFirstSchools]", "[lngSchoolCode]='" & Me.cboGetCode & "'")
This is working very well.Now, what I would like to do is get code as shown in the cboGetCode field to my sub form lngSCode field.

I'm using Access 2007. I have a few problems:
1. I have a switchboard. I want to click a button, that opens a form with a dropdown list, when I make my selection, it opens a subform in add mode, but the linked field in the subform isn't empty, but filled with the mainform's field value that I selected?
OR
2. Is there a way for me to open a form in add mode, add data to it, click the add button (I will add an add button) that allows me to add again, but this time a particular field is not empty, but filled with selected info from previous selection?
Say for instance, I have 2 fields (both combo box fields), I click add, made selections for both fields, I click add again, but this time one of the fields stays constant like it's already been selected. It's filled with what was selected from before.
Either of those 2 - which ever is simpler.

I have a Main form with a sub form.The main form is a customer record (form view), and the sub form is all other customers (same fields) datasheet view.I have a navigation bar to filter (using different queries) the results in the sub form
same postcode
Same company (different location)
everyone except Main form customer
I cannot get a different filter (Query) to show only customers whose name begins with the same letter as the customer in the main form?I have been trying Like but think I am referencing it wrong, as it prompts me to enter a value rather than using the value in the field in the main form.This is what I have in the query (of the subform)
Customer ID: <>[Forms]![NewAllCustomerListF]![CustomerID]
Customer Name: Like "[Forms]![NewAllCustomerListF]![CustomerName]" & "*"

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.

I created a main form containing list boxes and a subform. What I want to do is to select items in the list boxes. Then, by clicking "Search" button, the data filtered by the selected items will be shown in the subform. But the subform cannot work and show the query results. I think I miss some VBA codes.

I'm trying to sum a couple of columns from a subform datasheet and carry them onto the main form.
My main form, [frm_tours_details], holds subform [sbfTours] which is a datasheet.
On [sbfTours], I've got a couple calculated fields within the datasheet, one, called "txtStudentSum", which calculates number of people total ([students]+[adults]+[numfreeteachers]) and one, called "txtptotal", which calculates fee for the program based on the following formula:
Code:
=IIf([txtMonth]>=10 Or [txtMonth]<=4,([Students]+[Adults])*7,([Students]+[Adults])*8)
(The fee is $8/person in season, and $7/person out of season.)
I've been following online directions I found to put a text box in the form footer which then sums each of these calculated fields ("txtStudentSum" & "txtptotal"), and then reference these text boxes from my main form.
However, the main form text boxes just come up as #Name? or #Error when I try to reference these boxes on the subform. Or, sometimes, the one calculating total students will show the total of ALL students, adults in the database, not just those for this particular record-but only, it seems, if I have the subform open separately first, then load the main form. I also tried putting the whole original calculations into text boxes on the main form, but they will only reflect either the current record selected in the subform, or they will only show the first record, regardless of what you've selected, depending on which way I tried.
I've attached a copy of the database ... click on the tab 'tours', then click on, say, tour #6 (since this one is multiple programs and needs to calculate) to open the tour details form.

I've got a subform (simple table view) inside a main form, the subform (sfrmRecipes) just has an IngID field (which stores ingredient ID's) and a percentage field
I've added a few calculated fields to this subform, to assist users in making decisions, however each of these fields needs a sum total
So far my percentage field (which is an actual stored field in tblRecipes) is the only one with a functioning sum
for some reason the two calculated fields (which are both plain numbers, no text) do not give me a sum total option, i am only able to use the count function on them
Why calculated fields dont sum up and if there is an easy way to get it working (tried creating my own text field in the footer and manually typing SUM(fieldname), but it does not work).

hi, i would like to be able to prevent a user from being able to change a field (lock a field) in a main form if a field in a subform is complete. (the field in the subform is named: "new_weekly_base" if this is complete then i would like the field: "weekly base" to be locked on the main form. is this possible?, please help.
the main form is named: "SCREEN-MAIN"
the subform is named: "SCREEN-SUBFORM"
(the main form has a button on it which loads the subform.)
ive tried the below code but it doesnt work, any help would be excellent.
-------------------------------------------------------
Private Sub Form_BeforeUpdate(Cancel As Integer)
If [NEW_WEEKLY_BASE] >= 0 Then
With Me.WEEKLY_BASE
.Visible = True
.Enabled = False
End With
End If
End Sub

I have a database to track temporary decertification's. I have the expiration and max dates calculated out from the original dates at the top of each box. The temp expiration date is calculated by adding 267 days from the first date . When we enter an extension, the new expiration date is 30 days from the extension date. My question is, how can I make the expiration date update when a new extension is put in.
For ex.
Temp Decert Date: 05 Dec 2014
Temp Decert Extens 1:
Temp Decert Extens 2:
Temp Decert Extens 3:
Temp Experation Date: 31 Aug 2015
Max Temp Date: 04 Dec 2015
how can I make the expiration date update to go 30 days from what is in the extens field 1, 2, and 3 (respectively) instead of 267 days from the original date?
So I want it to look like this after updating a field
Temp Decert Date: 05 Dec 2014
Temp Decert Extens 1: 30 Aug 2015
Temp Decert Extens 2:
Temp Decert Extens 3:
Temp Experation Date: 29 Sep 2015
Max Temp Date: 04 Dec 2015

I have a "Main" form called frmProjects that sports multiple tabs. One of those tabs is labelled "Milestones", into which I inserted a datasheet subform called frmSubMilestones. The table that feeds the subform is tblMilestones. I established the parent / child relationship between frmProject and frmSubMilestones, and everything is working just fine...
To summarize: frmProject as main form -> Milestones Tab on main form -> frmSubMilestones as datasheet subform on the Milestones Tab (there are other tabs that are not subforms).
I have been asked, for each milestone in the frmSubMilestones subform's datasheet, to capture the number of days spent by employees on a monthly basis. The Milestones table and the PersonDays table have a primary key and a foreign key that are similar.
To summarize: frmSubMilestones as subform -> txtAggregatePersonDays as calculated Textbox fetching data from tblPersonDays -> OnClick event -> FormLoad of frmPersonDays as datasheet PopUp form.
DoCmd.FormLoad is supplied with the usual parameters to make the PopUp form appear, filtered on the currently highlighted milestone. Everything works fine so far... well almost.
Problem 1: When I introduce new rows in the frmPersonsDays datasheet, everything seems fine at the surface, BUT the primary key of the calling form (i.e. frmSubMilestones) does not appear in the tblPersonDays table; this is normal because there is no form-based parent / child relationship between the two forms. As one might expect, I am trying, from frmPersonDays, to get the primary key value from the "parent" frmSubMilestones using the Forms collection. No dice. I surfed and surfed, tried the bang and the dot operators, drank scotch, but nothing worked. I had to add foreing keys manually in tblPersonDays to further my tests. I can't figure out how to reach any control on the calling form, which is a subform.
Problem 2: The calculated txtAggregatePersonDays on the frmSubMilestones works wonders for existing data in tblPersonDays. However, when I introduce new rows in the PopUp form, I also realized that the calculated Textbox in frmSubMilestones is not updated when I close the frmPersonDays PopUp. I have to close the PopUp form and move the cursor in the Main form (frmProjects) to refresh its associated milestones.

I've read over and over that calculated data is bad, that's fine with me... but here is my dillema...
I have four fields that interact with my calculation in a single form. There is only one table in the database.
AmountF (The stored data in the table) (amount financed)
FC (calculated by =[amountf]*.25) (finance charge)
Amount Paid (used in calculation of total due)
total due (calculated by =[amountf]+[fc]-[amount paid])
The math already works, everything works. I can choose to print the form and it looks great. However, I would like for it to (when I'm done printing the form) somehow save the total due data to the AmountF column in the table. AmountF is in the same line as all the other information, so I would like it to not create a new record just update the old one.
All four of these fields have a text box in the form for themselves.
