How To Refer To Continuous Subform Contol
I have an Access 2003 form with one subform, set to continuous forms, in a subform control. For one record in the main form, 1 to many records will appear in the sub form. The data displays properly.
The main form is named Widgets and the sub form is named Transactions. There are 5 textbox controls that display the data in the subform. The one in question is ReceiptDate.
What I would like to do is look at the values and determine if there was a receipt for the year 2009, and if so then change the background of that row to yellow so it stands out when the user encounters that condition. Maybe even change the date field's font to boldface..
I tried many ways of referencing the subform's controls. When I have tried Me.Transactions.ReceiptDate I have only received the first record in that subform. I'd like to be able to loop through them and see if the condition is met. I tried Me.Transactions.ReceiptDate(1) and Me.Transactions.ReceiptDate(0) and so forth.
I tried the For Each ctl In Form.Controls route as well. It worked for a few iterations and then I received a run-time error 2455 "You entered an expression that has an invalid reference to the property Form/Report".
I had the subform in "datasheet" mode but thought that was causing me not to be able to read through an array of subform controls. So I changed it to "continuous" mode. I get the same errors for either.
Is there a way to reference specific "rows" in the subform and do something based on a value found? Also, I am performing this in the On Current event as I dont know where else to put the code. The subform loads before the parent form so its possible that these controls arent even fully "there" but then I do get the first row's date when I try it in the Immediate Window.
UPDATE 12.23.2010:
With the gracious help of @Remou I am able to debug.print the ReceiptDate fields from the RecordSet. This is great because now I can evaluate the data and do certain things based on the values.. The @Remou's code helped me put this into the OnCurrent event:
Dim i As Long
Dim frm As Form
Dim rs As DAO.Recordset
' Get the form and its recordset.
Set frm = Me.Form
Set rs = frm.RecordsetClone
' Move to the first record in the recordset.
rs.MoveFirst
' Move to the first selected record.
rs.Move frm.SelTop - 1
' Enumerate the list of selected records presenting the ReceiptDate field
For i = 1 To rs.RecordCount
Debug.Print rs![ReceiptDate]
rs.MoveNext
Next i
So now that I am able to know which row in my subform has a receipt from 2009, I need to be able to highlight the entire row or rows as I come across them in that for loop. How can I reference the actual row? Datasheet view or Continuous Forms view - I have tried both.
Conditional Formatting is great but it only allows me to highlight one particular record and I'd much rather be able to do this via VBA because...... from here I will want to give the use the ability to click on any record in the subform and get the receipt details and potentially print them.
Any ideas?
Answer
In this situation, it is best to use conditional formatting.
To refer to a control on a subform, refer to the subform control by name, then the form property to get the form contained, then the control by name:
Me.MySubformControlName.Form.MyControl
