Hi Marcia

If column 1 has a columnWidth of 0, it will still be used for the display value
===============================================================================

Exactly, the field the combo works off is column 1 (steetname) but I want to display column 2 (streetno) before column 1 (streetname). Hence by duplicating column 1 as column 3 (street name) in my fields(columns) list and giving column 1 (the display value) a '0' width (ie. hide it) I can have a streetno-streetname dropdown on a streetname field. (eg.

. Universal Street. ¥

. 12 Universal Street
. 159 Universal Street
. 267 Universal Street
. 569 Universal Street



How many address???
===================

The Work Order system is being designed to track and follow maintenance on customers houses (customer's clients). In the instance under consideration this can be 5000+ hence the desire to quickly reduce the quantity that the user has to choose from.

It was my intention to hold the key range to a null set until about two or three characters and then 'pop' the combobox with the remaining set. This could still be quite large 50+. The user can also put in partial street number to further filter the combobox.

It may be that I should perhaps be using a list box but this would require a significant amount of extra code and at this stage I have no prototype to work off.
