How can I put a listbox on a form that shows the value of a specific field all records deep?

How can I make clicks on this ListBox navigate in the database?

I want this ListBox to change if I change the database.

Can it be done at all?

Isn't it what you're trying to do just a single dbgrid with only one field in the Fields Editor??

This is a suggestion seeing that I really have no clue what you are attempting.  It seems to me though that you could accomplish this by making a DBGrid pretend to be a ListBox.  Set the grid up so that the DBGrid displays only one field, the field you are interested in.  Set its width accordingly. You could also get rid of the grid lines, etc.  You would think it was a list box when it was done.  Let me know if this is what your after and I can help.

Other words, check this out.

Add records to listbox

with Table1 do
begin
while not EOF do
begin
 ListBox1.Items.add(fields[0].asString);
end;
end;


now, in you listbox onClick event you can reference the item using ListBox.Items[ListBox.ItemIndex]

Use this string to perform a search and place the cursor on the
record.

There would be some table functions and maybe some sql's here, however, it could be done.

I think that's what I told before sholmes. But it'll be really slow if you try to navigate through the database using a search for each record you move to. Definately it's very slow. Just use a DBGrid, make it appear however you want and make it show only one record by means of its editor. This way you'll be able to move through the database just as if you had a listbox.
If you really need a more elaborated answer let me know, but I think there's not too much to elaborate here.

Hope this help
