Checkbox in a datasheet - cheating with a UNIQUES recordsource query?

I have a datasheet on a form that contains a checkbox.  

For one condition, the datasheet's recordsource is based on a UNIQUES query, thus the recordset is not updatable.  Therefore, the checkbox is not functional.  The UNIQUES query is required as the the condition produces duplicate results.  There are also two JOINS in the query and I have selected the Dynaset "Inconsistent Updates" option in the query and in the datasheet.

Can anyone suggest a method (or a cheat) to allow the checkbox to be "checked" even in this condition?  I do note that the double-click event is functional, single-click is not.

Any creative ideas?


Thanks,

Mark

The work around I see is to change the UNIQUES query into a maketable (or append) query to fill a temp table.
When checked you can use queries to manage the result in the normalized tables.
There's however the danger of intermediate updates (deletes) on the source tables, thus the only ultimate solution would be to create a main/subform to avoid the readonly recordset and to handle the rows properly.

Hi Mark,
Creative ideas huh....lol, lots.
How about this.

Seeing as how your datasheet view is acting more like a display than a selection option..Switch it's view to continuous forms. Put a button at one end beside the checkbox. put this as the on_click event of the button

Private Sub Command18_Click()
Dim strSQL As String
Dim lnID As Long
lnID = Me.ID.Value    '<----ID field of the displayed record
strSQL = "Update Orders set Check = -1 where ID = " & lnID   '<-----Replace table and field names with yours
DoCmd.SetWarnings False
DoCmd.RunSQL strSQL
   
End Sub
This will set your checkbox for that individual record.

IF you want to be able to click again and it goes back to "unchecked" then you'll want to make the code above based on an "IF"

something like this

Private Sub Command18_Click()
Dim strSQL As String
Dim lnID As Long
lnID = Me.ID.Value
blTrue = DLookup("Check", "Orders", "ID = " & lnID)
If Not blTrue Then
    strSQL = "Update Orders set Check = -1 where ID = " & lnID
Else
    strSQL = "Update Orders set Check = 0 where ID = " & lnID
End If
DoCmd.SetWarnings False
DoCmd.RunSQL strSQL
Me.Requery
End Sub
