Search form using two fields in combobox

Hi Experts,

How do I create a combobox on a form to search for records using two fields in the recordsource?  I've used the wizard but it will only bring me to the first field in the query.  Thank you for your help!

Well, normally, you would use two separate combo boxes to filter your recordset on the values in two separate fields.  I usually add two buttons (Filter and ClearFilter) next to the combo boxes.  Then in the cmd_Filter_Click event:

Private Sub cmd_Filter_Click

    Dim strFilter as string

    if me.cboFilter1 & "" <> "" then strFilter = "([Field1] = " & me.cboFilter1 & ")"

    if me.cboFilter2 & "" <> "" then
        if strFilter <> "" then strFilter = strFilter & " AND "
        strFilter = strFilter & "([Field2] = " & me.cboFilter2 & ")"
    endif

    me.Filter = strFilter
    me.FilterOn = iif(strFilter = "", False, True)
End Sub

Open in new window

This assumes that the values displayed in cboFilter1 and cboFilter2 are both numeric.  If either of those is a text string, then use something like:

strFilter = strFilter & "([Field2] = " & chr$(34) & me.cboFilter2 & chr$(34) & ")"

Then in the cmd_ClearFilter button:

Private Sub cmd_ClearFilter_Click

    me.cboFilter1 = NULL
    me.cboFilter2 = NULL
    me.filterOn = false

End Sub

Open in new window

Hi Dale,

Would an end-user be able to find a single record if both of the comboboxes were used?

I'm guessing that the single combobox option won't work?

Thanks!

Well, you could create a single combo box which would have a RowSource something like:

SELECT DISTINCT Field1, Field2 FROM yourTable ORDER BY Field1, Field2

You would then have to set the combo box to display 2 columns (when it expands), but a combo will only ever display a single value when when the combo is colllapsed.  This is why it would be preferable to use two combo boxes.
