I have a main form and a subform on it. I want the recordsource of the subform to change depending on the value of an ID field of the main form. This works when I do it in the Form_Load event of the parent Form. However, I also want it to update when the user switches to a new record on the main form (single form) while it is open.
The code I have atm is the followng:
Private Sub Form_Load()
'***************************************************************************
'Purpose: Switch subform recordsource based on recipe ID
'Inputs: None
'Outputs: None
'***************************************************************************
Dim strRecipeID As String
Dim strSub1QueryName As String
strRecipeID = Forms![frmMainForm]![RecipeID] 'get RecipeID
strSub1QueryName = DLookup("[QueryName]", "tblRecipeQueries", [RecipeID] = strRecipeID) 'Get name of query
Forms!frmMainForm!frmSub1Sub.Form.RecordSource = MakeSqlString(strSub1QueryName) ' Set Subform1 recordsource
End Sub
MakeSQLString() is a function that gets the SQL SELECT statement as a string from a given access query. I tried the change event, the Click event and the Current event and requerying the subform after that but none have any impact on contents of the subform (the recordsource does not change) but stays the same one that was selected when the form loaded.
I'm not sure which other events could work for this or from where I can execute the change in recordsource most effectively, maybe the subform instead? Maybe it has something to do with the subform loading before the parent form? I'm not sure, might be a rooky mistake.
I appreciate any help. BTW, the fields on the subform stay the same, so changing the recordsource just updates the calculations that are made in the query to get the values for those fields. The query names are stored in a table in my db. Again, It works in the Load event of the main form I just can#t get it to update on the fly while the main form is open and the user navigates to a new RecipeID on said main form.
In your DLookup you are not enclosing the where portion in quotes. You have:
DLookup("[QueryName]", "tblRecipeQueries", [RecipeID] = m_selectedId)
But it should be:
DLookup("[QueryName]", "tblRecipeQueries", "RecipeID =" & m_selectedId)
That should take care of your issue.

I have two forms:
InterviewMaster and InterviewDetail
InterviewDetail opens up as a subform in InterviewMaster and these two forms are linked through a common field called InterviewID
In InterviewDetail I have a textbox called Questiontype as well as combobox called InterviewDropdown.
The data in the dropdown varies based on the data on in the textbox. To make this happen, I have a next button to move to the next question. Whenever I click on next the following runs:
Dim ctlCombo As Control
Set ctlCombo = Forms!InterviewDetail!cmbInterviewDropdown
ctlCombo.Requery
The Row Source setting for my combobox is set to look up the required answers, again this is based on the value as per the textbox:
SELECT [queryAnswerOptions].[Answer] FROM queryAnswerOptions ORDER BY [Answer];
So the options are determined by my query called queryAnswerOptions
So as I cycle through my questions using my next and previous buttons, the dropdown options are updated based on the value of my textbox. This works perfectly when I open the subform from the navigation pane. However, when I open the main form and click on the next button my dropdown does not have any values. I've tried requerying the subform with no luck. I've also tried opening the subform in full screen from my main form but this also does not work. I also don't want to go that route as it does not work well with the overall flow of my form.
Any assistance will be greatly appreciated.
Problem with the query WHERE criteria parameter is when form is installed as a subform, the form reference no longer works because it must use the subform container control name. I always name container control different from the object it holds, such as ctrDetails.
Option is to put SQL statement directly in combobox RowSource instead of basing combobox RowSource on a dynamic parameterized query object - then it will work whether form is standalone or a subform.
SELECT Answer FROM InterviewAnswers WHERE QuestionID = [txtQuestionID] ORDER BY Answer;
I want to populate my ComboBox in an Access form using VBA based on data from another table. Previously to do this I did the following:
In the Property Sheet -> Data tab I filled out Row Source and Row Source Type fields with this information:
Now whenever I clicked on the dropdown for my combobox, it would populate the dropdown list with all of the names from t_people table.
This limited me however to when data changed in the t_people's name column. In order to get an updated list, I must close the form and re-open it so that the query runs again. I have limited the access to this Access file so that the user is only presented with x number of forms, and cannot close/open them or others.
My solution is to remove the query on the form load, and instead run the query every time the combobox gains focus, has a click event or something of the same sorts. I did this with the following event in VBA:
'Run when the "name" combobox gains focus
Private Sub nameCb_GotFocus()
[nameCb].RowSource = "SELECT name FROM t_people"
End Sub
I have set breakpoints and this code does run. However, the the combobox is not populated after it does. How can I get the combobox to populate with the values from a query for each time the combobox gains focus?
Set the RowSource in design and add a .Requery when entering the control.
Private Sub nameCb_Enter()
nameCb.Requery
End Sub
Imagine a form that, for demontration purposes, contains only a subform and a textbox that need to mirror each other.
I tried to accomplish this by setting the Control Source on the textbox to the value of the field in the subform and this worked to make them mirror each other, but the textbox isn't editable so this is an unsuitable solution.
The next thing I decided to try was using the AfterUpdate event on both controls to run code that sets the value of the other control.
This is easy for the textbox:
'Set value of Notes field on subform whenever value of the corresponding textbox
Private Sub Notes_Textbox_AfterUpdate()
Me.subform.Form![Notes] = Me.Notes_Textbox.Text
End Sub
However, this isn't as simple for the subform field. I don't know how to reference an event on a field in a subform in a way that will still allow me to reference controls outside that subform.
As a demonstration, I need a way to do this:
Private Sub subform_Notes_AfterUpdate()
Me.Notes_Textbox.Text = Me.subform.Form![Notes]
End Sub
I can access the subform fields AfterUpdate event within the scope of the subform but if I do that, then I can't access the Textbox because it is in the main form, not the subform.
So I either need a way to define an event function on a field in a subform from within the scope of the main form, or a way to make the textbox part of the subform while maintaining the subforms ability to open in datasheet view.
Not sure I get the whole problem (how does datasheet view come into play?), but this should do what you want:
(in the subform)
Private Sub Notes_AfterUpdate()
Me.Parent!Notes_Textbox.Value = Me![Notes].Value
End Sub
Edit from comment: By far the easiest solution would be a continuous form instead of a datasheet in a subform.
You can have two textboxes, a one-liner in the Details section, and a large one in the form header or footer. Both have the same control source and are automatically updated when the other one is edited. No code required.
If it must be a subform-datasheet, you can use a similar approach: bind the main form to the same recordsource, and in On Current of the subform, move the main form to the same current record.
I have a subform within a form.
In this subform I enter line per line the mail-addresses of customers.
I want to set a mailstring like this into the parent form of the subform.
Example in Subform:
mail1#test.com
mail2#test.com
mail3#anothertest.com
whenever I leave the field "mail" on subform a string such as
mail1#test.com; mail2#test.com; mail3#anothertest.com
should be put into field "Parentmail" on mainform.
It is not the problem to CREATE the mailstring (3 mailaddresses) but on WHICH EVENT on the subform (or field on subform) can I run the function??
I tried
Form_AfterUpdate
(subform !) but it only works when I add new mail-addresses or when I update an existing one, not when I delete one.
Which event will fire when I have maybe 3 mail-addresses and delete one?
Form_Delete
did not do the job.
Thx Michael
Try the subform BeforeDelConfirm event: Replace(mainformfield, subformfield & ";", "").
I've built an unbound form which allows a user to select from two combo boxes that contain related information (Zone and Watershed Unit -- each Zone contains multiple watershed units) in order to see what regulations apply to each. Based on these selections (stored in txtZone and txtWU on the main form) a subform would show the existing regulations (sfrmRegsbyZWU based on qryRegsbyZWU). This serves as a reference for the user, who picks a new regulation to add from another subform, clicks a button, and the selection is added to the regulations for the Zone/Watershed Unit selected. I had this successfully built with a workaround in the OnCurrent event of the subform (which was undesirable because the user couldn't click on a record and delete it) and everything worked until I added inserted code to change the query definitions for the query which is the basis for the subform as opposed to having it in the "On current" event of the subform.
At that point the requery syntax in the main form which had previously worked stopped working. This is in all embedded in a navigation form in Access 2010, so the previously working syntax was:
Forms!frmNav!NavigationSubform.Form.sfrmRegsbyZWU.Requery
I've tried every permutation of Requery I can think of, and I can not get it working. The underlying query has been changed, but the form doesn't update to reflect it. Can anyone explain to me what has gone wrong, and how to fix it? The code (attached to the _After Update() event of the combo boxes) is:
Private Sub cboZone_AfterUpdate()
'Changes WU combo box as well as the underlying text boxes
Me.cboWU.SetFocus
Me.cboWU = ""
'Blank out other selections
Me.txtWU.SetFocus
Me.txtWU = ""
'Update text box with combobox selection
Me.txtZone.SetFocus
Me.txtZone = Me!cboZone.Column(0)
'Change the query underlying the Existing Regs panel (frmRegsbyZWU, qryRegsbyZWU) to reflect selection
Dim strZSQL As String
Set qdfZ = CurrentDb().QueryDefs("qryRegsbyZWU")
Dim myZVar As Variant
myZVar = Forms!frmNav!NavigationSubform.Form.txtZone
'MsgBox (myZVar)
If IsNull(myZVar) Then
strZSQL = "SELECT * FROM tblRegulations WHERE FALSE"
Else
strZSQL = "SELECT * FROM tblRegulations WHERE Zone_No=" & Forms!frmNav!NavigationSubform.Form.txtZone
End If
'MsgBox (strZSQL)
qdfZ.SQL = strZSQL
'DoCmd.OpenQuery ("qryRegsbyZWU")
Forms!frmNav!NavigationSubform.Form.sfrmRegsbyZWU.Requery
Thanks in advance for any help!
