Set Controls Default Value from another Control

I am working on a form for data entry where the user enters many records that
may have similar information, i am trying to create a tab that would have all
of my "Default" values so that for example if the user was going to enter 40
items from a PO they could go to the Defaults tab and enter the PO# and every
record they enter on the subform would by default have the PO number entered.

I have done this before where my data entry textbox controls default value
is =me![DefaultNotestext] where [DefaultNotesText] is on my Defaults Tab and
it is bound to a 1 record table so the value is there if i close and reopen
the form.

The 1 record table seems excessive can the [DefaultNotesText] be a Unbound
text box that can somehow be set to store the value indefinately

or on activate get the current default value from my NotesText control and
with the afterupdate set a new Default value to my notesText property?

Any help would be greatly appreciated
Thanks

Barry,

Stop amd review the design of your tables. You should have something like:
TblPO
POID
PODate
VendorID
<other fields pertaining to the whole PO>

TblPODetail
PODetailID
POID
POItem (might be ItemID if you have a TblItem)
ItemQuantity
ItemCost

TblPO records data about the PO as a whole. TblPODetail records each item on
a PO, its quantity and its price. Data entry is by a form/subform. The main
form is based om TblPO and the subform is based on TblPODetail. You set the
Linkmaster and LinkChild properties to POID. You don't need to enter POID
for each item in the subform. Access automatically enters POID for each item
in the subform. This ensures each item in TblPODetail is associated with a
specific PO (POID).

...every record they enter on the subform would by default have the PO
number entered.
The data of the subform should be the many side of a one-to-many
relationship and the Master/Child links between the form/subform set on the
primary/foreign key fields with cascade update so that the PO number does not
need to be entered at all.
No need for a table to hold your default information as once it is loaded
into the form fields as default it stays there. What you could do is to
have an event such that after change to set current values as default for
those fields that are expected to be repetive.

me using "PO" as an example may have been misleading. I am looking for an
easy way for the User to set a fields "Default" value based on their
preference or current project..

the best i could come up with is a "Defaults Tab" on the form with duplicate
controls to hold the "default values" I think your After Change event is
what i am after. how would i code the following? I guess it would have to
be in the "Defaults Tab"'s On-Click event.

Me!NotesDefaultTextbox = Me!NotesTextbox(How do i get the current default
value?)

then in the NotesDefaultTextbox On-Change?? (if its unbound what event do i
want to use??)
Me!NotesTextbox(How do i set the new default value?) = Me!NotesDefaultTextbox

Im there just not thinking right on the details..

Thanks

Hi Barry,

I have faced similar requirements - actually concerning default amounts.
Let me relate my experience.

Rule: Do not prefill fields with default values. Sloppy users [:-)] will
occasionally not check to see whether the default value is actually
appropriate in this case.

There are now two design decisions to make:

1. How to signal to your application that the field should be filled with
the default value;
2. Where to store and how to maintain default values.

For 1 I used the double click event. However you hint that this is a volume
data entry situation and I would suggest a keyboard trigger (or detection of
a null) is more appropriate

For 2 the world is your oyster! Where to store user defaults and
preferences has to be determined. For a single machine/multi-user
environment then the registry is as good a place as anywhere. For a split
application (client/server) then something serverside is required.
(Performance issues?) As for maintaining the default values, I see nothing
wrong with your idea of developing a user form for the purpose.

Finally I found it a useful visual aid to colour the fields differently when
filled by a default value whether retrieved automatically or typed directly.
