Question

Limiting Records in Combo box?

Asked by: 4charity

I am looking for a good way to structure the relationship between 2 forms. The first form has a button on it that opens the second form. I would like to limit the records that open on the second form. That is easy, using the button wizard. However, on the second form, I need the user to pick the correct record to work on (and load into the form.) Right now, I have a combo box that lists all records, and they choose which one they would like, and that populates the form. But it lists *all* records... Is there a way to limit the list in the combo box? I tried setting the criteria in the underlying query to the field in the previous (first) form, but it doesn't seem to like that. Or, is there just a better way to accomplish this task?

Two easy ways to filter the records to show only the record selected:

1) With the bound column of the list/combo box is the record ID field.

Private Sub List/ComboBoxName_AfterUpdate()       'Use the name of your list/combo box
Me.Filter = "txtRecordID = " & List/ComboBoxName       'Use the name of your list/combo box and text box
Me.FilterOn = True
End Sub

2) Again, the bound column of the list/combo box is the record ID field.

In the query that is the record source for the form, create a criteria like this:
[Forms].[YourFormName].[ComboBoxName]       'Use the name of your list/combo box and form name

OK. In response to the nelson, I have a combo box that works, and populates the form nicely. That is not the problem. The problem is that there are over 35,000 records in the entire DB, and it takes too long to load the combo box. I want to limit the results of the combobox to the several records which fulfill the [ClaimNumber] criteria, which is defined on the previous form. I have tried setting the combo box [ClaimNumber] criteria to [Forms]![frmClaimInformation].[CorrectedClaimNumber], which refers to the [ClaimNumber] on the previous screen. As I stated, I get a popup, asking me to enter that data, to run the combobox. Is there a different syntax I should be using?

Or, is there just a better way to do this?

[Forms]![frmClaimInformation].[CorrectedClaimNumber]
You are my mixing up your bangs and dots.  In your query, either use
[Forms].[frmClaimInformation].[CorrectedClaimNumber]
or
[Forms]![frmClaimInformation]![CorrectedClaimNumber]


Also look at

BTW:
"As I stated, I get a popup, asking me to enter that data..."
First time you mentioned that.

thenelson,

Thanks for the response. Sorry for the snarky "as I stated" --- I guess it was more of an "as I thought, but did not state." =D

The syntax in the last example you gave works -[Forms]![frmClaimInformation]![CorrectedClaimNumber]. But not in using the info from the first form. Still does not like that. I worked around it by also setting the [CorrectedClaimNumber] as a field on the second form, and reference that field in my underlying query for the combo box. Works fine, but still begs the question if it is possible to pull this value from a different form (not the current one.)
Thanks.

Solution gave correct syntax, but did not work in method requested. Please read my follow-up response to get the complete solution.

Forms and reports have controls.  Tables and queries have fields. So when you stated "I worked around it by also setting the [CorrectedClaimNumber] as a field on the second form,", did you mean you created a control with the name of CorrectedClaimNumber?   Using [Forms]![frmClaimInformation]![CorrectedClaimNumber] refers to a control in the form so that control must exist. It can be invisible if you don't want users to see it. The syntax [Forms]![frmClaimInformation]![CorrectedClaimNumber] will get the value of any control of any OPEN form.

For more info, see:

Glad to help and thank you very much for the points with "A" grade!

Happy computing!

Nelson

Yes, I put a control with the name of [CorrectedClaimNumber] on the form with the combo box. Still had some issues trying to get the value from the other form (I'd have to go back and look - perhaps I am closing that form on opening the new one.........)

Thanks for the help.
