I'm setting the control source of text fields to return the value of a function (multiple fields with different filtering conditions). The form has a combo box with a list of years: when the user selects a specific year, the on change event triggers a refresh of all the fields.
My problem is the fields don't show any values unless after combo box's On Change events. I have to click on the form/fields before the values start showing up.
I tried to do form refresh & field's requery but doesn't work.
The text field's Control Source is set to:
=SummaryReport("Projects","G","1",[Forms]![frmSUMMARY_REPORT]![cmbYEARS])
What I'm trying to do is when the user selects a year from a drop down, the fields values are updated & displayed by the On Change event - currently they seem to be updated but are not showing unless I click on the screen and that's when values start showing up in each field.
The method to update calculated fields is Me.Recalc (or myForm.Recalc):
https://learn.microsoft.com/en-us/office/vba/api/access.form.recalc
Try this instead of .Refresh.
Also I think the better event to use is After Update instead of On Change for a combo box.

I am trying to filter a subform based off a value selected in a listbox.
My list box is called cboCurrentListName and this is populated using a select query
The subform is called Form_subform_ListContents
For the change event for the list box I have the following code, however no filters are applied when its executed.
Me.Form_subform_ListContents.Form.Filter = "[ListName]=" & Me.cboCurrentListName.Value
Me.Form_subform_ListContents.Form.Filter = True
I have also tried using Master/Child links to execute this using the following steps, but this caused an input box to pop up when the fom loaded:
first I set the 'link child fields' option in the properties of the subform to 'ListName' (this is the field name that populates the list box and is present in the subform
then I set the 'link master fields' option in the properties of the subform to 'cboCurrentListName' (the listbox name)
then in the listbox properties I set the control source to 'cboCurrentListName'
The above steps cased an input box to pop up on opening the form (the value typed in here does filter the subform). However I don't want an input box in order to do this, I want to use the listbox.
I have googled this and fried different methods but have had no luck. I am pretty new to access and of the control source sections aren't a strong point of mine, which is why I tried to use the VBA on the event change instead
Any help would be appricaited, I tried a few things and had no luck.
EDIT: When trying the master/hild option I also get an error 'Can'y build a link between unbound forms' if I click the 3 dots in the poperties. SO for the above steps I had to manually type in the otpions.
In access I am trying to get my total value to be equal to the sum of the all of the different values where the order number is the same.
My current code is as follows;
= SUM( Forms![OrderLine]![Total] ) Where( Forms![OrderLine]![OrderNo] = [OrderNo] )
This however gives me an error. How else would this be done?
Thanks
It sounds like you have an Order form and an OrderLine subform. Add a Form header/footer to your OrderLine form and put a text box in the footer. Put a SUM function in the Control Source of the footer text box to generate the aggregated value you need from the order line item rows.
On your main form, set the Control Source of the text box you want to display the order total equal to the name of the invisible text box in the subform. The control source on the main form text box will resemble SubformControlName.Form.AggregateTextBoxName.
You may need to play with the visibility settings of the header/footer, text box, form view mode, etc. to get the presentation you want, but this works even with the subform in datasheet view. The key is to get a text box somewhere on the subform to calculate the value you need on the parent form and then reference it inside the subform control from the parent form.
Firstly, I'm pretty new to access so I apologise if this is basic but I can't find the right answer either.
I've had some help setting this up so there are parts that have been created that I don't fully comprehend.
I have created a form that is to be used for data entry which consists of the following fields:
TEAMS - Combobox the rowsource of which is a table TEAMS; CALLREASONS - Multi-Select Listbox the records of which currently exist in a table CALLREASONS; ACTIONS - Multi-Select Listbox the records of which currently exist in a table CALLACTIONS; SUBMIT - Button with VBA which sends selected data to a number of tables.
The database works fine and things a saving where they should be and in the format they should be, the problem I'm having is with the display of the form.
I would like for the form to display blank when opened and after each time a record is submitted. However, if I set the rowsource of the listboxes to the tables all options show when the form is loaded and after each submission the options and the previous selections show.
How can I make it so that the first listbox CALLREASONS only displays possible options once a selection has been made in the combobox TEAMS and the second listbox CALLACTIONS only displays possible options once at least one selection is made in the listbox CALLREASONS ?
Thanks in advance for any help.
You can either change the controls row sources on the Update or Enter events, or you can simply enable/disable them on the events.
Lets use 3 nested comboboxes for an example.
Combo1 Has rowsource set permanently as it is the top level.
Combo2 and Combo3 Have no rowsource set.
On the Enter event of Combo2, you can set the rowsource to
SELECT Pkey, DisplayText FROM tblOptions WHERE OptionGroupField = " & Forms!Form1!Combo1BoundField
On the Enter event of Combo3, you can set the rowsource to
SELECT Pkey, DisplayText FROM tblOptions WHERE OptionGroupField = " & Forms!Form1!Combo2BoundField
So on so forth.
I have created a form and set the form's RecordSource to a query. Below is my query:
SELECT GeneralT.*, SalaryT.[Status]
FROM GeneralT INNER JOIN SalaryT ON GeneralT.Deposits = SalaryT.Deposits;
In the form I have 4 textboxes. In the first 3 textboxes I show value from GeneralT table and in fourth textbox I show SalaryT.[Status] value. But this fourth value doesn't show in the textbox rather it show #Name?.
If I open the query in datasheet view I can see all the value properly. I don't understand what is wrong here. Please help me to show the result properly in the form.
Displaying #Name? for a field says that field has a control source that does not match with the query linked to the form. Some things to check:
Make sure Status is a selection from one of the pre-existing options in the Control Source drop down combo box. Click on the combo box to make sure.
Double check to make sure it is a "Text Box" and not a custom
control.
Make sure there isn't another text box named Status
Try chaning the control source to just Status instead of SalaryT.[Status]. If the field name does not conflict with the naming of a field in GeneralT, the selected SalaryT.[Status] will actually be displayed named Status.
I have a standard form in MS-Access which lists a bunch of orders, and each row contains order no, customer, etc fields + a button to view notes and attached document files.
On request from our customer we should gray out the button btnAnm (or check or uncheck a checkbox) depending on a calculation from two queries to two other tables (a SELECT COUNT WHERE and a check if a text field is empty).
I've tried btnAnm_BeforeUpdate(...) and btnAnm_BeforeRender(...) and put breakpoints in the subs, but none of them trigger. The same if I use the control Ordernr instead of btnAnm.
I'd like a function in the Detail VBA code to be triggered for each "Me." (row) so to speak, and set the row's control's properties in that sub.
What do I do? I've looked at the help file and searched here.
*Edit: So I want to do something that "isn't made to work that way"? Ie. events are not triggered in Details.
As an alternative, could I base the value of a checkbox on each line on a query based on the 'Ordernr' field of the current row and the result of a SELECT COUNT from another table and empty field check?
Do I do this in the query the list is based on, or can I bind the extra checkbox field to a query?
A description of how to do this (combine a COUNT and a WHERE "not empty" to yes/no checkbox value) would be perfectly acceptable, I think! :)*
You cannot do much with an unbound control in a continuous form, anything you do will only apply to the current record. You can use a bound control with a click event so that it acts like a button.
Presumably the related documents have a reference to the order number that appears on your form, which means that you can create a control, let us call it CountOrders, with a ControlSource like so:
=DCount("OrderID","QueryName","OrderID=" & [OrderID])
The control can be hidden, or you can set it up to return true or False for use with a textbox, you can also use it for Conditional Formatting, but sadly, not for command buttons.
Expression Is [CountOrders]>0
You can also hide the contents and add a click event so that is acts in place of the command button. Conditional Formatting will allow you to enable or disable a textbox.
As I understand your question, you have a continuous form with as command button that appears on each row - and you'd like to enable/disable the button conditionally depending on the contents of the row.
Unfortunately you can't do that. It seems that you can't reference the individual command buttons separately.
Having wanted to do something similar in the past I came up with two alternate ways of setting up my interface.
Put a trap into the onClick code for the Button. Which is icky, because it is counter intuitive to the user. But it gets you that functionality now.
Move the command button (and editable fields) up into the form header, and make the rows read only. Your users then interact with the record only in the header, and select the record they want work with in the list below. As I recall this is known a Master-Detail interface.
