Question

Is there a way to populate a TListbox control with items from a database column?

I know the proper way to do this is to simply use a DBLookupListbox control and set it up to access the column I want, but the problem with that is when I click on one of the items in the lookup control, it changes the current row in the dataset (expected behavior) but I do not want this to happen.

Instead, I would want the current row to be changed only on a double click event in the lookup control and since I do not think this behavior is possible to change, I thought it would be easier to simply use a normal TListBox instead, but as I stated above, I am not sure how it’s done.

So once again, I have come to the experts for some advise on how to populate a normal Tlistbox control with items from a database column.

There are a myriad of ways to solve your problem. You could create a hacked control of a TDbLookupListBox and override the Click method to do nothing. You could also create a second dataset to be used for your lookup. But as you wish, to populate a TListbox, you simply iterate the dataset and add the field value to the listbox as:

tLogin.first;
while not tLogin.eof do
begin
  Listbox1.Items.Add(tLogin.fieldbyname('fullname').asstring);
  tLogin.next;
end;

If you need a key value based on a selection, then this won’t solve your problem entirely. You’d be better off hacking the TDbLookupListbox control, imo.
