>>>I am wondering what is the best approach to take when we have a listbox of type 1 - Value where we enter our own values in RowSourceType property. It's not like a listbox of type 3 - SQL where we can bound the control source to field on BoundColumn 2. Basically, what is the best approach to bound the control source when entering the values manually at the form designer level?

For example, we have a full description 1 and a full description 2. But, we only save a small description 1 and a small description 2.


michel -

i see this is an old thread, and you may well have gotten your answer by
now, but i didn't see a complete answer to your actual question, so ...

if you specify 1-Value for rowsource type for a listbox, you can
include a code that corresponds to the description that you actually
display to the user. you can also hide or display the code, as you
wish.

your row source could look like this:

1,Apple,2,Pear,3,Orange,4,Banana

set column-count = 2
set bound-column = 1
set column-widths = 20,100

your listbox will look like
1 Apple
2 Pear
3 Orange
4 Banana
'value' of Orange will be 3.

(or of course you could use a "short description" instead of a number).

to hide the first column,
set column-widths = 0,100
