Subject Lookup List

It's been a long day, and I'm dropping, but I am so nearly
there with this one.

I have a now addition to a project, which is actually using
the grid to add the order items. One of my first <g>

I have all the pop-up's working except for one, and I am not
quite sure what I should be using.

I want a drop down list populated with a set of values which
is contained the the product code table. I have had it
working with it displaying the DESCRIPTION while updating
the PARTNO, but in this instance I only want to display the
PARTNO list and update PARTNO in the order items table, so I
don't need the cross reference to a different display field.

What component should I be using to drop onto the IB_Grid
into which to put a simple list of PARTNO values?
